Quadrilateral Current Mode Paralleling of Power MOSFETs for Zero-Voltage Switching
IEEE Transactions on Power Electronics, 2021 This paper proposes a generic zero-voltage switching (ZVS) scheme for parallel power MOSFETs. Uncoupled or inversely-coupled differential-mode (DM) commutation inductors are added to the midpoints (AC terminals) of parallel MOSFET half-bridges (HBs), and a time-delay-based control scheme is applied, generating a circulating current flowing through ...
