ABSTRACT
The unidirectional AC–DC boost converter is realized as a bridgeless PFC converter. This can be used for power quality improvement by mitigating its indices. Conventional boost PFC converters are composed of a full-bridge AC-to-DC diode rectifier followed by a boost converter. The bridge rectifier suffers from high conduction losses, which lower the system efficiency. The control strategy for PFC control is explained in this chapter. RPC, HCC, and combined RPC and HCC are explained in detail. Simulations and their corresponding results for PFC are illustrated in this chapter.
