Abstract :
High-voltage bipolar-mode static induction transistors (BSITs) are applied to a zero voltage switched (ZVS) pulse width modulated (PWM) power converter to increase efficiency and reduce volume and weight. The BSIT switches have significantly less power loss than conventional switches such as MOSFETs and IGBTs. Efficiency of 95% in a 40 kHz, 10 kW (53 V/200 A) converter is achieved by applying a ZVS PWM DC/DC power converter, high-voltage BSITs and a new BSIT driving method.<>
