摘要
Currently, the gate driver design method of SiC MOSFET is mostly inherited from the Si MOSFET and IGBT. However, since SiC MOSFETs have higher switching speed than Si devices, it is also worth exploring the gate-source voltage interference caused by gate internal resistance, gate driver inductance and power circuit inductance. In this paper, the process of gate-source voltage interference is analyzed, and then the method of driver parameter per-united design based on interference dynamic response mechanism is summarized and extracted. This paper deduces the transfer functions of the power loop and the driver loop according to the equivalent circuit of the junction capacitance. Then, the interference dynamic response mechanism is revealed. Furthermore, a per-united parameter expression form is introduced to quantify the influence of gate driver parameters on the interference conduction path of gate-source voltage. The SiC MOSFET gate driver design principle is proposed based on the interference dynamic response mechanism. Finally, a double-pulse experimental platform was built to verify the rationality of the driver design principle. © 2021, Electrical Technology Press Co. Ltd. All right reserved.
