Switching characteristics and efficiency improvement with auxiliaryresonant snubber based soft-switching inverters [PDF]
, 1998 The auxiliary resonant snubber inverter (RSI) has demonstrated superiority in reduction of switching losses and dv/dt. It was found that the overall inverter system efficiency might not be improved if the resonant current was not controlled in accordance

Ultra High Step‐Up Soft Switching Converter Based on the Interleaved Structure
Energy Science &Engineering, Volume 14, Issue 1, Page 540-556, January 2026.The proposed topology provides high voltage gain and enhanced efficiency at low duty cycles, thereby reducing conduction losses in the switches. Its interleaved structure ensures current sharing, while the switches experience both low voltage and low current stress, further decreasing conduction losses.

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 ...

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
