摘要：

A small signal model for zero-voltage-transition pulse width modulation (ZVT-PWM) buck converters is proposed in this paper. It shows that the ZVT-PWM buck converter exhibits better dynamical behavior than the conventional PWM buck converter. Based on the derived model consisting of line voltage disturbances and load variations, mu-synthesis is applied for a robust controller design to achieve performance requirement. In addition, a classical controller and a sliding mode controller with modified integral variable structure are also designed for performance comparisons, Finally, simulation and experimental results are presented to verify the requirement for robust performance of ZVT-PWM converters.
