Abstract :
This paper proposes an improved ZVT-PWM boost converter. The main switch of the conventional ZVT-PWM converter is always switched at zero voltage. But the auxiliary switch is turned-off with switching loss due to hard switching condition. Therefore, the proposed converter reduces the turn-off switching loss of the auxiliary switch by using an additional circuit. All of the losses for the switches are minimized, and high power density system can be realized
