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.
