N2 - In this work, based on the duty-cycle-shifted-PWM half-bridge converter, a zero-voltage-switching-PWM (ZVS-PWM) half-bridge converter is proposed. Both main switches of the proposed converter achieve zero-voltage-switching and the converter uses constant-frequency operation. The small-signal mathematical model for the ZVS-PWM half-bridge converter is derived. Notably, it is verified that the dynamical behavior of the ZVS-PWM half-bridge converter is better than that of the conventional PWM half-bridge converter from a system point of view. The accuracy of theoretical results is verified by simulation and experimental results. A classical controller is then designed to achieve fast output voltage regulation despite variations in line voltage and load resistance.
