摘要：

A gate driver with efficient energy recovery based on bidirectional buck/boost converter is proposed. The proposed gate-drive circuit is constructed by power supply, energy storage module and energy converter. Instead of discharging directly in conventional gate drivers, gate charge Q(g) in the proposed gate driver is released to the storage capacitor during turning-off transition of power MOSFET. Principle of the proposed gate driver is analysed, and design consideration of key parameters are also suggested. The gate-drive losses of the proposed gate driver and resonant gate driver are, respectively, tested as 0.102 and 0.125 W at 100 kHz. The test result proves that power consumption of the proposed gate driver is significantly decreased.
