Abstract

This study investigates an active gate driver (AGD) for an SiC-MOSFET. The source current feedback type AGD utilizes the induced voltage of the source wire inductance as a negative feedback signal to regulate the source current di/dt. Recent improvements in the switching performance of the AGD is limited due to the feedback system bandwidth. In this paper, a high bandwidth current feedback type power operational amplifier is applied as the gate drive circuit. Switching characteristics of the conventional resistive gate driver and AGD are experimentally investigated via a double pulse test setup. The switching setup condition is 700 V / 80 A. This paper describes the development of the AGD circuit and experimental results. The over-shoot and ringing of the Vds and Is are reduced using the AGD. Moreover, the switching loss is simultaneously reduced.

同时降低开关浪涌和开关损耗的高带宽有源栅极驱动器

本研究研究了用于SiC-MOSFET的有源栅极驱动器(AGD)。源电流反馈型AGD利用源导线电感的感应电压作为负反馈信号来调节源电流di/dt。由于反馈系统带宽的限制，最近AGD开关性能的改进是有限的。本文采用高带宽电流反馈型功率运算放大器作为门驱动电路。通过双脉冲实验装置，对传统阻栅驱动器和AGD的开关特性进行了实验研究。开关设置条件为700v / 80a。本文介绍了AGD电路的研制和实验结果。使用AGD可以减少Vds和i的超调和振铃。同时降低了开关损耗。
