A nanosecond pulse generator (NSPG), with a high peak voltage, short-duration pulsewidth, high repetition rate, and fast rise/fall times, has gained traction and is now used in several applications such as plasma, biomedical, and industrial. The pulse characteristics vary with the type of application and these are affected by the choice of the switching devices in any topology and other elements of NSPG. Therefore, a variety of NSPGs have been researched, which makes the selection of any particular topology for NSPG development a challenging task. Thus, to address this gap, the literature presents a review of several conventional and state-of-the-art topologies of NSPG with high-power (HP) switching devices such as spark gap, solid-state switches, magnetic switches, and other elements for various applications. It also presents the pulse’s duration, voltage, current, power, rise/fall time, and repetition frequency for different applications. Furthermore, strategies for minimizing switching losses and other losses that substantially lower pulse generator efficiency are also discussed. Finally, a concise evaluation of available switching devices and other elements of NSPG, their pros and cons, and future directions are discussed to provide a clear understanding to designers and researchers.

Robust and intelligent control algorithm design is very essential in the development of power electronics converter to maintain constant output voltage regardless of the variations in input voltage and load. In this article, simulation and analysis of interleaved DC-DC converter for electric vehicle charging applications using adaptive neuro-fuzzy inference system (ANFIS) are presented. The ANFIS based control algorithm for the DC-DC converter is designed to stabilize output voltage and enhance the performance of the system during transient operations. To verify the design, two-phase interleaved synchronous DC-DC buck converter is simulated in MATLAB-Simulink based environment and simulation results on resistive load are presented.

In this article, the design and development of a fast rise time high-voltage bipolar impulse generator (HV-BIG) system for a dielectric barrier discharge (DBD)-based coaxial 222 nm excimer radiation source has been carried out for effective plasma generation. Full bridge topology utilizing silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors (MOSFETs) along with a step-up transformer has been realized for the development of the HV-BIG system. Sectionalized windings were designed to realize the primary and secondary winding of high-voltage transformers. The fabricated high-voltage transformer features a uniform distribution of the primary and secondary windings to minimize leakage inductance. A control algorithm has been implemented to generate 180 $^{\circ}$ phase-shifted gating pulses with suitable pulse repetition frequency and pulsewidth for the full bridge converter. The developed laboratory prototype of the HV-BIG system was experimentally verified with the DBD-based Krypton/Chlorine (Kr/Cl $_{2})$ excilamp to generate 222 nm radiation with output pulse voltage ranging from $\pm$ 2.85 to $\pm$ 8.25 kV. The HV-BIG system has been experimentally tested to generate variable high-voltage bipolar pulse output voltage with a pulse repetition frequency of 31.5 kHz and tunable at two distinct pulsewidth of 1.0 and 1.2 $\mu $ s.

This article presents a model-based approach to assess the battery performance of a two-wheeler EV drive train system for various user driving patterns using the selected urban drive cycles. The battery pack is one of the most expensive parts of an EV, and its life is heavily dependent on its usage pattern. The impact of the user’s driving behaviour on the performance parameters of the EV battery pack needs to be investigated. Thus, a two-wheeler EV drive train model was developed in MATLAB with a 5 kW motor, a 4.32 kWh battery, vehicle dynamics, and the power train control algorithms for in-depth analysis of battery performance. The validity of the developed model was tested against various state-of-the-art drive cycles for a duration of 3600 s. Numerous user driving behaviours, such as aggressive, moderate, and slow driving behaviours, were modelled with modified drive cycles, which were used to assess the two-wheeler battery pack performance. An optimum speed range, which ranges from 21 km/h to 34 km/h for different drive cycles, was identified, and these speed ranges minimised the battery energy consumption for the selected drive cycles with the modified drive cycle models.

Developing a robust and reliable high-voltage (HV) pulse power system (PPS) is essential for the characterization and testing of microwave tubes and industrial applications. This paper presents the design, simulation, and implementation of a modular and versatile high-voltage pulse power supply used in microwave device characterization and testing. A microcontroller-based digitally controlled pulse generation unit is also developed to generate the trigger pulses for high-voltage switching modules to control the turn-ON and turn-OFF of the switching devices. The digitally controlled pulse generation unit provides better resolution of pulse width, pulse repetition frequency, and system protection over the entire range of operations. The pulse generation and control circuit controls the pulse repetition frequency (PRF) and pulse wide (PW). The PRF and PW can be varied from 100 to 1000 Hz and 10 to 100 µs, respectively. The experimental prototype with ten series-connected high-voltage modules is connected to achieve a 25 kV pulsed output voltage. The experimental results of HV-PPS on a resistive dummy load and 5 GHz klystron tube are presented in this work.
