This paper presents the comparison of two gate driver boards, which are operated with the same power module. One solution is realized using a gate current control driver IC, while the other solution uses a conventional gate driver IC with external buffer. The power module is a 1200 A / 1200 V module designed for high power applications. The paper compares the functionality of both boards and analyses the switching performance. As comparative condition, the turn-on collector-emitter slew rate of dvCE/dt = 5 V/ns is used. Particular interest is in the evaluation of the turn-on energy.
