ZVT PWM Boost Converter

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 turn-off with switching loss due to hard switching condition. Therefore, the proposed converter is reducing the turn-off switching loss of the auxiliary switch by using additional circuit. All of the losses for the switches are minimized, and high power density system can be realized.
