This paper presents the experimental validation, using the opposition method, of a high-power three-phase Wireless-Power-Transfer (WPT) system for automotive applications. The system under test consists of three coils with circular sector shape overlapped to minimize the mutual cross-coupling, a three-phase inverter at primary side and a three-phase rectifier at receiver side. In fact thanks to the delta configuration used to connect the coils of the electromagnetic structure, a three-phase Silicon Carbide (SiC) inverter is driving the transmitter side. The resonance tank capacitors are placed outside of the delta configuration reducing in this way their voltage sizing. This WPT system is used as a 100 kW–85 kHz ultrafast battery charger for light delivery vehicle directly supplied by the power grid of tramways. The adopted test-bench for the WPT charger consists of adding circulating boost converter to the system under test to perform the opposition method technique. The experimental results prove the effectiveness of the proposed structure together with the validation of fully exploited simulation analysis. This is demonstrated by transferring 100 kW with more than

Nowadays, the demand for high power converters for DC applications, such as renewable sources or ultra-fast chargers for electric vehicles, is constantly growing. Galvanic isolation is mandatory in most of these applications. In this context, the Solid State Transformer (SST) converter plays a fundamental role. The adoption of the Medium Frequency Transformers (MFT) guarantees galvanic isolation in addition to high performance in reduced size. In the present paper, a multi MFT structure is proposed as a solution to improve the power density and the modularity of the system. Starting from 20 kW planar transformer model, experimentally validated, a multi-transformer structure is analyzed. After an analytical treatment of the Input Parallel Output Series (IPOS) structure, an equivalent electrical model of a 200 kW IPOS (made by 10 MFTs) is introduced. The model is validated by experimental measurements and tests.

Introduction: Antimicrobial resistance is a worldwide problem accounting for the reduction or in some cases absence of drugs effectiveness normally used in infections treatment. In the light of the even more spread ability of microbials to develop resistance, there is an urgent necessity to find novel and alternative routes to fight infections. Natural compounds or extracts can be a valid alternative either as monotherapy or as adjuvant in order to improve the effectiveness of the failing drugs. Areas covered: This review provides a comprehensive update (2018-2020) on the development state of innovative antimicrobial agents based on natural compounds and extracts, also describing their compositions, methods of production and use, mechanism of action, along with anti-microbial data when available. Expert opinion: Owing to the pivotal role that natural compounds often cover in the finding of novel drugs, their in-depth analysis could pave the way to the discovery of new antimicrobial agents. Most of the alternative approaches reported in this short review were validated through in vitro and in vivo (animal as well as human) models. The employment of natural derived compounds and extracts, alone or in combination with classical antimicrobial drugs, as antimicrobial agents could represent an important achievement to challenge pathogens resistant mechanisms.

A large library of saccharin and acesulfame derivatives has been synthesised and evaluated against four isoforms of human carbonic anhydrase, the two off-targets hCA I/II and the tumour related isoforms hCA IX/XII. Different strategies of scaffold modification have been attempted on both saccharin as well as acesulfame core leading to the obtainment of 60 compounds. Some of them exhibited inhibitory activity in the nanomolar range, albeit some of the performed changes led to either micromolar activity or to its absence, against hCA IX/XII. Molecular modelling studies focused the attention on the binding mode of these compounds to the enzyme. The proposed inhibition mechanism is the anchoring to zinc-bound water molecule. Docking studies along with molecular dynamics also underlined the importance of the compounds flexibility (e.g. achieved through the insertion of methylene group) which favoured potent and selective hCA inhibition.

In this paper a strategy for charging process control of a dynamic wireless power transfer system is introduced. The control scheme is composed of both transmitter and receiver controls. A current control is employed in the transmitter side in order to control the transmitter current in misalignment condition. In the receiver, a power control is used. According to the power demanded by the vehicle, the control in the receiver, regulates the transmitter voltage using an active rectifier. The operation of the control in both transmitter and receiver is without any communication link between two sides. The behaviors of the quantities of the system in different reference powers, mutual inductances and frequencies are investigated. Furthermore, the proposed control scheme is simulated in order to validate the theoretical analysis.

These rules aim at the construction of down-scaled prototypes allowing the study and the design with benefits in terms of costs, time consumption and flexibility. The theoretical results are experimentally validated by comparing a 1.1kW system with its down-scaled version.

The paper presents a particular Pulse Width Modulation (PWM) strategy to reduce the (Direct Current) DC-link capacitor stress for multi-n-phase drives. A multi-n-phase drive is composed of multiple independent systems of n inverter supplying a multi-n-phase electric machine. The paper focused on the investigation of the best phase shifting between carriers for a triple-3-phase drive compared to the 3-phase counterpart in order to reduce the capacitor bench design point. Simulation and experimental results show as the control technique proposed is able to reduce the value of the DC-link capacitor current in any operating condition including fault case. In this sense, the PWM carrier displacement appears like an additional degree of freedom that can be exploited in multi-n-phase drives but also in multi-motor application.

This paper proposes a technique for the control of the charging process in a dynamic inductive power transfer system for automotive applications. This technique is based on an impedance control loop on the receiver side. The proposed control allows different phases of the charging process to be carried out in the absence of a communication link between the ground and the vehicle side. The charging process starts with a sensorless procedure for the identification of the actual presence of the vehicle over the receiver. The same control technique introduces several advantages of interoperability between systems having different requirements in terms of the power demand. A 11-kW prototype has been implemented based on a transmitter 1.5-m long as compromise solution between the long track coil and the lumped one. The power management of the receiver side is provided by a nine-phase interleaved boost converter. The experimental results prove the effectiveness of the proposed control together with a good matching with the developed theoretical equations set for the system description.

The paper discusses two wireless power transfer systems for the charge of electric vehicles during the motion. The systems are conceived to be interoperable with the same receiver structure. Both systems are supplied by means of the same power electronics architecture and are based on the series-series compensation of the coils. In one of the presented systems a high-frequency transformer is used at the transmitter side. The two solutions are analyzed and compared pointing out their advantages and drawbacks. Results of experimental tests are presented to demonstrate the operations of both systems.

The paper proposes a simple solution to a safety problem encountered during the development of a series-series compensated IPT system for electric vehicles. This problem is related to the equivalent current source behavior of the receiver side in presence of an unpredicted load disconnection. A pure analog hardware system able to manage this fault protecting the filtering elements of the system is proposed. The system is investigated by means of a circuit simulation then its physical implementation is presented. The effectiveness of the proposed solution is experimentally proven.

Over-voltage at the motor side when supplied by Voltage Source Inverter (VSI) using long cables could cause winding failure and it is known to be source of electromagnetic disturbances, both radiated and conducted. In this paper, the over-voltage prediction for such drives in industrial environment has been investigated. Minor run time execution and precise simulations are the main paper targets. A novel cable model has been considered for motor over-voltage and converter over-current estimation. Two different measurement methodologies for the model parameters have been introduced too. The first methodology is accurate and could measure both the proposed parameters needed by the application and the filter parameters needed to mitigate these problems. The second is simpler and could only estimate the filters parameters. Comparison between experimental and simulation results are presented in the paper to confirm the proposed methods.

The paper presents peculiar multi-n-phase low torque ripple permanent magnet machine solutions. It will be shown that a particular choice in the phases to poles relationship allows to obtain a low torque ripple machine. A simple parametric model allows prediction of torque ripple harmonic orders. Once a simple stator structure is chosen, different rotors topologies have been coupled in a simulation environment. The simulations compare the different multi-n-phase solutions and their corresponding 3-phase counterparts showing the better performance of the multi-n-phase one. The torque performance of the machines are also evaluated under fault condition in the multi-n-phase solutions.
