摘要

This paper describes the design of a fast response zero-voltage-transition (ZVT) pulse-wdith modulation (PWM) boost converter. The techniques employed in the design include a combination of a PWM variable gain control and zero-voltage switching (ZVS), to improve the switching speed and efficiency of the converter for high frequency operation. A prototype was built to verify the design and to compare the proposed variable gain controller and the conventional controller using PWM. It is shown that with the proposed controller, the ZVT boost converter has a much faster response than the conventional PWM control. Moreover, the proposed controller is easily realized with simple analogue circuitries.
