Synchronous Rectifier Spike Reduction During Continuous Conduction Mode Operation of a Power Converter
An active switch QAUX is used to reduce the voltage spike on a synchronous rectifier (SR) QSR which may occur during continuous conduction mode (CCM) operation of a power converter. The use of the active switch QAUX also provides zero voltage switching (ZVS) for the turn-on of the primary switch Q1 and reduce primary side switching losses.
