The research on the driving technology for SiC devices has always been a hot issue for scholars both at home and abroad. The existing active drive technology realizes the regulation of switching transient by changing the drive resistance, drive voltage or current. It requires many components, and the drive board is bulky and costly. Therefore, a full-bridge active drive technology based on resonant drive is proposed. By switching on and off the drive switch tube only, different drive circuits are constructed to form different drive currents, thus realizing the switch transient adjustment. First, the 1/4-period full-bridge resonant drive is taken as a reference drive mode for the power tube. Then, a specific design method for active drive switch timing is given by analyzing various stages during the switching on process of the power tube. Finally, through simulations and experimental verification, it is found that the drive mode can reduce 87.0% of current overshoot during the switching on process and 4.2% of voltage overshoot during the switching off process, and it can also achieve flexible speed regulation in a wide range of specific stages.
