Optically Triggered Self-Adaptive Zero Voltage Switching
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 Converters
Contact is the principal method of applying loads between deformable solids,and therefore is present in a wide variety of mechanical components. In addition,contacts usually act as stress concentrations,and are thus probable locations for mechanical failure.

Zero voltage switching double-ended converter
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 ...
