Soft-switching Methods and Optimization of Output Stage of MOSFET Driver

Abstract

This paper focuses on design and comparison ofoptimization methods for the output stage circuit of MOSFET gatedriver. Optimization methods aim to reduce voltage swing inducedon parasitic series inductance of package terminals. In order todetermine the effectiveness of proposed optimization methods,individual designs are compared with original MOSFET gatedriver circuit designed by Onsemi company. These optimizationmethods should improve performance of MOSFET gate driver inthe field of high-frequency use, where induced parasitic voltagecan cause false signals, interference or even breakdown ofunprotected structures.
