Bulky capacitors are usually needed to buffer the double-frequency ripple power (DFRP) in single-phase power factor correction (PFC) rectifier. It is important to reduce the capacitance requirements for improving the system reliability and power density. In this paper a control method for capacitive idling converter based PFC (CIC-PFC) rectifier is proposed. The DFPR is diverted to the energy transfer...
Bulky electrolytic capacitor is usually needed in bridgeless power factor correction rectifiers to buffer the double-frequency ripple power (DFRP). However, it reduces the system reliability and power density significantly. This letter proposed a control method to divert DFRP to the small energy transfer capacitor. Then, the bulky electrolytic capacitor can be replaced with a small film capacitor...
