Abstract

A series voltage compensator is proposed for power factor corrector (PFC) in power conversion systems. The introduced concept can reduce the dc-link capacitors used for balancing input and output power, limiting voltage ripple and maintaining certain period of hold-up time if required. Therefore, it allows replacing aluminum electrolytic capacitors by alternative ones with long lifetime while achieving high power density and cost effectiveness. The voltage compensator processes the ripple voltage of the dc-link and supplies reactive power only. It can be implemented by low voltage switching devices and passive components. Simulated and experimental results of a boost PFC converter verify the theoretical predications.
