A novel dead-time generation method of clock generator for resonant power transfer system

Abstract

This paper presents a novel dead-time generation method of the clock generator for the resonant converter system. The new dead-time generator, which is incorporated to implement the accurate dead-time independent of the output frequency of the clock generator, is designed to prevent cross conduction problem for half-bridge type resonant converter circuit. Dead-time variation range is from 50 ns to 2 μs.
