Research and Analysis of Equivalent Circuit Model for Core Snubber

Journal of Physics: Conference Series, 2023
Abstract The ion source is the key to the NBI. It is very sensitive to overvoltage and overcurrent, and the breakdown frequently occurs between the acceleration grid. The core snubber is the most suitable surge suppression device to achieve DC fault protection.

Design of the resistor-capacitor snubber network for a d. c. circuit containing an inductive load

, 2023
In most of the power electronic circuits, it is necessary to minimize the effect of the excessive rate of increase of the voltage across the devices due to which they could be overstressed.

Recent Advances in Hybrid, Plug‐In, Battery, and Fuel Cell EVs: Control Schemes, Modes, Converter Topologies, and Pros and Cons

IET Electrical Systems in Transportation, Volume 2026, Issue 1, 2026.
Direct current (DC)–DC converters are the backbone of electric vehicle (EV) power trains, enabling efficient and bidirectional energy flow between the battery, high‐voltage (HV) DC link, and auxiliary rails under tight isolation, gain, ripple, and electromagnetic interference (EMI) constraints.

Multi‐Layer MTDC Protection: Design and Simulation Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...

Harmonic elimination of a fifteen‐level inverter with reduced number of switches using genetic algorithm

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This article presents a Fifteen‐level inverter topology that has a lesser number of switches (12) and can accommodate isolated DC sources. The total harmonic elimination (THD) of the proposed topology using genetic algorithm is within the IEEE 519 standards. Further, the fifteen‐level inverter is implemented in Hardware and firing pulses were generated
