Abstract
This paper presents an active gate driver with variable gate resistance for use in SiC-driven inverters. Motivated by the negative effects that fast switching transients of SiC MOSFETs may have on the insulation and bearings of electrical machines, the operation theory of the active gate driver and its hardware concept are explained. Measurements with both the active gate driver and a reference gate driver are presented. A method is proposed to mathematically determine the optimal control pattern for the active gate driver. The measurements show that an active gate driver can achieve an optimal tradeoff between dv/dt and losses. In a modified control scheme, the voltage overshoot during turn-off can also be decreased. The benefits of using an active gate driver in an inverter when adjusting the control patterns to the switched current are outlined.
