Development and production of ZCS soft switching converter-based gate driver IC

Abstract

In this paper, design of ZCS soft switching converter-based gate driver monolithic integrated circuit (IC) is presented. The circuit is developed in B6035 high-voltage bipolar process technology of Sichuan Institute of Solid-state Circuit. It consists of voltage detection logic, switch driving, isolation transformer excitation voltage blow-down unit circuits. The circuit and the isolation driving transformer jointly comprise the driving circuit of power MOS transistor. The principle of ZCS switching resonance is used to design the circuit. The circuit can drive MOS transistor with low power efficiently, and is especially suitable for the driving circuit of high-power ZCS soft-switching power supply.
