In this paper, we propose a method for the identification of the differential inductance of saturable ferrite inductors adopted in DC–DC converters, considering the influence of the operating temperature. The inductor temperature rise is caused mainly by its losses, neglecting the heating contribution by the other components forming the converter layout. When the ohmic losses caused by the average current represent the principal portion of the inductor power losses, the steady-state temperature of the component can be related to the average current value. Under this assumption, usual for saturable inductors in DC–DC converters, the presented experimental setup and characterization method allow identifying a DC thermal steady-state differential inductance profile of a ferrite inductor. The curve is obtained from experimental measurements of the inductor voltage and current waveforms, at different average current values, that lead the component to operate from the linear region of the magnetization curve up to the saturation. The obtained inductance profile can be adopted to simulate the current waveform of a saturable inductor in a DC–DC converter, providing accurate results under a wide range of switching frequency, input voltage, duty cycle, and output current values.

In this chapter, a survey of LED driver circuits is presented. The driver circuit is a crucial component in the LED light system. It provides the correct voltage and current values for the best brightness and long life. Furthermore, the driver circuits contribute to obtaining high efficiency and reliability light system. Several lighting applications need different driver topologies that meet the use requirement and the energy sources available. In actual applications, passive and active circuits are implemented to satisfy the LED driver electrical requirements and cost-effective demands. The LED driver circuits investigation evaluate the issues and the solutions in the LED lighting systems connected to a DC source such as a battery or AC line. The AC line connection requisites such as the power factor correction and the harmonic distortion are dealt with both the driver topology and control optimization. Also, the volume reduction need is examined in the circuitry choice. Moreover, the different topologies of the power converters isolated and not isolated used in the driver circuits based on both the power request and supply source are described and critically evaluated.

This paper presents a complete design methodology of a Class-E inverter for capacitive wireless power transfer (CWPT) applications, focusing on the capacitance coupling influence. The CWPT has been investigated in this paper, because most of the literature refers to inductive power transfer (IWPT). However, CWPT in perspective can result in lower cost and higher reliability than IWPT, because it does not need coils and related shields. The Class-E inverter has been selected, because it is a single switch inverter with a grounded MOSFET source terminal, and this leads to low costs and a simple control strategy. The presented design procedure ensures both zero voltage switching (ZVS) and zero derivative switching (ZDS) conditions at an optimum coupling coefficient, thus enabling a high transmission and conversion efficiency. The novelties of the proposed method are that the output power is boosted higher than in previous papers available in the literature, the inverter is operated at a high conversion efficiency, and the equivalent impedance of the capacitive wireless power transfer circuit to operate in resonance is exploited. The power and the efficiency have been increased by operating the inverter at 100 kHz so that turn-off losses, as well as losses in inductor and capacitors, are reduced. The closed-form expressions for all the Class-E inverter voltage and currents waveforms are derived, and this allows for the understanding of the effects of the coupling coefficient variations on ZVS and ZDS conditions. The analytical estimations are validated through several LTSpice simulations and experimental results. The converter circuit, used for the proposed analysis, has been designed and simulated, and a laboratory prototype has been experimentally tested. The experimental prototype can transfer 83.5 W at optimal capacitive coupling with operating at 100 kHz featuring 92.5% of the efficiency, confirming that theoretical and simulation results are in good agreement with the experimental tests.

In modern power electronics-based power systems, accurate modeling is necessary in order to analyze stability and the interaction between the different elements, which are connected to it. State space modeling seems a valid approach to study the modes of a certain system and their correlation with its states. Unfortunately, this approach may require complicated calculations and it is difficult to model advanced or emerging control techniques for grid-tied converters, such as cascaded controllers (e.g., voltage and current) and virtual synchronous generators (VSGs). Moreover, this approach does not allow an easy reconfiguration of the modeled system by adding, removing of modifying certain elements. To solve such problems, this paper presents a step-by-step approach to the converter modeling based on the Component Connection Method (CCM). The CCM is explained in detail and a practical example is given, by modeling one exemplary VSG model available in the literature. The obtained model is finally validated experimentally to demonstrate the practical accuracy of such approach.

In this article, a three-leg interleaved boost Power Factor Corrector (IBPFC) converter for energy-efficient LED lighting systems connected to the main grid was discussed. This IBPFC circuit presented features 60 kHz of commutation frequency and up to 3 kW of power rating. The controlled rectifier front-end boost PFC supplied a DC/DC converter to drive power LEDs suitable for street lighting or a lighting system for a stadium, etc. The IBPFC operated in continuous current mode (CCM). The ripple impact of the IBPFC converter was analyzed and a novel methodology of inductance design was presented. In the proposed design approach, the derivative calculation of the current ripple peak compared with the derivative of the input current was used to define a critical inductance value to ensure the CCM condition. Experimental validation was provided on a 3kW prototype.

Fuel cells (FCs) are typically low-voltage sources, they are connected in stack structures to increase the operating rate voltage. An efficient DC-DC converter is needed as interface between FCs source and a constant dc bus. In this paper a different approach is proposed. Single cells are individually considered in a connection with an suitable DC-DC converter to provide the overall stack voltage as a sum of the each power converter output voltages. DC-DC Push-Pull power converter that manages a single module fuel cell has been investigated. The proposed solution allows to reduce the mismatching of FCs in a stack arrangement and possible damage of a single or groups of FCs module. Low input voltage (0.5-1V) is the most critical parameter of the converter design. Simulation results are presented by using accurate models of the devices used for the prototype realization in order to investigate several operative conditions leading the simulations results as close to reality. Finally the experimental tests on the circuit prototype realized are performed with several transformer cores selections with different magnetic permeability value in order to individuate the better solution for the Push-Pull High Frequency (HF) transformer design.

This paper presents an analytical model of the impedance between two coils supported by ferrite shield. The new model is not restricted to round coils and applies to more complex winding geometries, as specified by the Wireless Power Consortium. The mutual inductance is derived by solving Maxwell's equations and using Bessel function of the first kind. The model results are compared with experimental data as a function of the vertical displacement between the coils. In addition, a wireless power transfer system is modeled to calculate system efficiency by adopting the above coils impedance model. Experimental results run on 5W wireless power transfer system at several displacement steps are compared against simulation data.

This paper presents a power-loss model for Lateral- Diffused MOSFETs (LDMOSs) in application-specific integrated circuits (ASICs) in the field of wireless power-transfer system applications. Both the transmitter and receiver power-stages integrated in their respective ASIC units were considered, and the total system efficiency was subsequently estimated. Layout parasitics pertaining to the primary and secondary integrated circuits (ICs) have been considered due to their impact on the total system efficiency, and a charge-sheet control model for the LDMOSs of the three power stages has been developed. Thermal effects induced by heating within the two ASICs were also included, as they exert a significant influence on the amount of both conduction and switching losses. Model results and experimental data are compared and show a satisfactory agreement.

This paper presents a multi-objective genetic algorithm (GA) for a wireless power transfer system composed of a full-bridge series-resonant inverter (FBSRI), a synchronous full-bridge rectifier (SFBR) and a buck converter. The proposed algorithm maximizes the total system efficiency by optimizing the switching frequency of the FBSRI and the SFBR output voltage, subject to their respective design constraints. Two application-specific integrated circuits (ASICs) respectively integrating the transmitter and receiver power-stages along with their controllers were optimized by the new algorithm. A discrete-time small-signal model of the system has been developed to analyze the stability of the wireless charger. Experimental results validating the above analysis are reported along with simulation data. The wireless power transfer system analyzed in this paper conforms to Wireless Power Consortium (WPC) specifications.

The main aim of this work was the analysis of the transient thermal behavior of several typologies of power MOSFET devices. The commonly used thermal model has been applied to different device families with different breakdown voltages. The large difference between the experimental results and the simulation runs, performed with the classic approach for some kinds of devices, leads to correct the traditional mathematical thermal model and to build up a new one in which the real size of the epitaxial layer is taken into account. A new model will be shown performing a better fitting with the experimental evidence and confirming its suitability for all the proofed families of devices. The mathematical process developed to build up the model is shown, and a comparison is carried out between the measured temperatures on the device and estimation by the model. The results discussed in the paper show how the developed model allows a better fitting of the achieved model with the experimental measurements and demonstrate the suitability of the proposed approach.

The thermal behavior knowledge of IGBT devices is very important to address issues related to the thermal management. Experimental measurements could provide the junction temperature of the devices in transient or steady state conditions. However, in case of short circuit, it became very difficult to get the temperatures because of the very short time in which the phenomenon happens (order of microseconds). Fortunately, thermal models represent a valid aid for the designers to predict the junction temperature but such models fail when used to study the short circuit. This paper deals with a new thermal model to address the temperature prediction in short circuit condition and it is composed by two different sub-models. The first can predict the heating phase of the phenomenon in a limited volume of the device without heat exchange, while the second is generated by taking into account a greater volume with the parameter values and physical sizes of the layers affected by the heat produced in short circuit.

The aim of this paper is to explore the switching capability of an improved high-voltage Super Junction MOSFET in half bridge resonant LLC converter. Due to suitable technological process, a considerable reduction in silicon conduction losses per area unit has been observed. Moreover, a reduction in the parasitic capacitance (i.e. gate charge) with an improved switching behavior has been obtained. In this paper, LLC resonant converter is selected because it operates at high switching frequency allowing to work with small size of the power transformer. The main benefit of this converter consists in zero-voltage switching (ZVS) of the MOSFETs. The converter is well suitable for applications such as PV systems. In this work the design procedure of LLC Resonant Converter is presented. Laboratory prototype was built to evaluate the performances of SJ MOSFET. Experimental results show an efficiency up to 94%.

Background. YKL-40 association with human disease has been the object of many years of investigation.β-thalassemia patients are affected by hepatic siderosis, which determines a fibrotic process and tissue remodelling. Chitotriosidase has been found to be increased in thalassemic patients returning to normal in patients submitted to bone marrow transplantation. YKL-40 is associated with macrophage activation in liver and in other tissues. The aim of the study was to analyse the level of serum YKL-40 and plasma chitotriosidase activity of patients with beta-thalassemia to assess whether their expression correlates with liver disease and degree of liver siderosis.Methods. Expression of YKL-40 and chitotriosidase as a marker of inflammation in 69 thalassemic patients were evaluated. We sought to investigate whether these two chitinases could be considered as a significant biomarker to evaluate therapy effectiveness.Results. Surprisingly we found normal value of YKL-40. We, also, analysed chitotriosidase activity in the same patients that was slightly increased as a consequence of macrophage activation.Conclusions. These data would suggest a good treatment for these patients.

The aim of this work is the development of an improved model for the analysis of the transient thermal behavior of MOSFET power devices in UIS conditions. The proposed modeling technique allows to achieve a higher accuracy for the estimation of the temperature of the power semiconductor if compared with classical models. The epitaxial thickness of the device is taken now into account in a bi-dimensional domain, thus accounting both for the heat flux generation and propagation on the plane (valid assumption, but only for low voltage devices) but also along the other dimensions. The new developed model presents more accurate results than the ones previously presented and doesn't make use of empirical correction factors. The mathematical process to build up the model is developed, and a comparison is carried out between the measured temperatures on the device and the estimation by the model. The results are shown and the good fitting of the simulation runs with the experimental measurements demonstrates the correctness of the proposed approach.

The plasma concentrations of SH groups were correlated to cytokines (IL-1b, IL-6, IL-8, TNF-α), plasma chitotriosidase (Chit), metalloprotease (MMP2–9), intercellular adhesion molecule-1 (ICAM-1).Results.The results demonstrated a significant reduction of SH groups within 24 hours from the onset of an acute ischemic stroke, a reduction of plasma IL-1b, IL-6, and IL-8, and an increase of Chit and TNF-αin relation to the stroke severity.Conclusion.The observation of an intense microenvironment activation that follows the stroke and the correlation between SH levels and markers of immune response suggest that, especially in stroke, is necessary to maintain the redox function to prevent the brain damage. The reduced SH levels represent an attempt to neutralize the abnormal generation of free radicals. Since the reperfusion of brain after ischemic event represents a severe oxidative stress, which must be corrected by regeneration of redox sensitive function, pharmacological intervention could be beneficial in this setting.

The paper deals with a smart load priority control strategy for Photovoltaic Uninterruptible Power Supply (PV-UPS) system. This hybrid uninterruptible power supply system achieves an auxiliary source of energy supply from photovoltaic modules, which operates in case of blackouts by providing a set of loads determined by the continuity of service during the absence of power supplied by the AC network. The proposed system is mainly designed for the field of home appliances. The proposed solution is based on a stand-alone photovoltaic system with a conventional UPS. A key role is played by an intelligent control strategy that handles both the charge of a suitable stack of batteries and the electrical loads connected to UPS. UPS enables loads to be supplied by assigning them an index of priority established by the operator, depending on their importance or safety.
