Abstract EN
This paper proposes a zero-voltage-transition (ZVT) pulse-width-modulated (PWM) synchronous buck converter, which is designed to operate at low voltage and high efficiency typically required for portable systems.
A new passive auxiliary circuit that allows the main switch to operate with zero-voltage switching has been incorporated in the conventional PWM synchronous buck converter.
The operation principles and a detailed steady-state analysis of the ZVT-PWM synchronous converter implemented with the auxiliary circuit are presented.
Besides, the main switch and all of the semiconductor devices operate under soft-switching conditions.
Thus, the auxiliary circuit provides a larger overall efficiency.
The feasibility of the auxiliary circuit is confirmed by simulation and experimental results.
