Abstract
The commutator for a bridgeless PFC circuit is characterized in that a synchronous half-wave rectifier is connected between a bridgeless PFC boost circuit and an AC power source and is coupled to the two terminals of the AC power source. The synchronous half-wave rectifier contains a first synchronous transistor, a second synchronous transistor, and a control circuit.
