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 ...
