A New Asymmetrical Current-fed Converter with Voltage Lifting
Advances in Electrical and Computer Engineering, 2011 This paper presents a new zero voltage switching current-fed DC-DC converter with high voltage gain. In this converter all switches (main and auxiliary) turn on under zero voltage switching and turn off under almost zero voltage switching due to snubber

Optically Triggered Self-Adaptive Zero Voltage Switching
IEEE Transactions on Power Electronics, 2023 Zero voltage switching (ZVS) is useful to increase power electronics efficiency but difficult to achieve due to the nonlinear parasitic capacitance of the power semiconductors and varying load current. This letter proposes a self-adaptive ZVS method by using the intrinsic electroluminescence (EL) property of SiC mosfets to automatically adjust the ...
