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 ...

Zero voltage switching double-ended converter
IET Power Electronics, 2010 A new zero voltage switching (ZVS) converter with a double-ended rectifier is presented to reduce switching losses on power semiconductors, decrease voltage stresses on rectifier diodes and achieve bidirectional power delivery to output load. A buck-boost type of active snubber is connected in parallel with the primary side of a transformer to recycle ...
