Abstract

To reduce the rectifier bridge conduction loss, different topologies have been developed. Among these topologies, the bridgeless boost does not require range switch and shows both simplicity and high performance. Without the input rectifier bridge, bridgeless PFC generates less conduction loss as compared to the conventional PFC. Although the circuit structure is simple, the location of the boost inductor on the AC side makes it difficult to sense the AC line voltage and inductor current. At the same time, since the AC side inductor structure makes the output floating regarding the input line, the circuit suffers from high common mode noise. Compared to the average current mode control, one cycle control shows many benefits such as no multiplier requirement, no input voltage sensing requirement, and no inductor current sensing requirement. Therefore, one cycle control gives an attractive solution for the bridgeless PFC circuit. In this paper, One Cycle Control technique is implemented in the bridgeless PFC. By using one cycle control both the voltage sensing and current sensing issues of the bridgeless PFC circuit can be solved. The experimental results show both efficiency improvement and good power factor correction function. At the same time EMI results show that the circuit noise is controllable.
