一种用于PFC变换器的电压尖峰限制与效率提升的实时可变关断电流策略

The voltage source driver (VSD) is widely used in a conventional gate drive circuit of the power factor correction (PFC) converter. However, the fixed drive current of the VSD circuit could not optimize the switching losses, and the turn-off voltage spike across the power switch is freewill. In this letter, a real-time variable turn-off current strategy of a power switch for the PFC converter is p...
