A new compact, isolated and integrated gate driver using high frequency transformer for interleaved Boost converter

Résumé

This paper deals with the design and the implementation of an integrated gate driver for interleaved converter. It is based on a novel gate driver topology for power switches like MOSFETs and IGBTs. Composed of two legs of a CMOS inverter, a high frequency pulse transformer and two Zener diodes connected with the gate of power switch, this driver topology provides an optimal bipolar gate driver waveform with greater positive and negative gate bias to switch ON and OFF. It represents a simple, ultra-compact, isolated gate driver. We have integrated several driver systems in CMOS technology (Austria Micro System 0.35 μm) in order to reduce power consumption, system size and to increase the robustness of gate driver. Therefore, this integrated driver circuit can be used for any multi-transistor applications. The operation principle of the proposed driver topology is detailed in this paper. The integrated gate driver is able to control a three phase interleaved Boost converter; the results show the effectiveness of the proposed driver system.
