Abstract

A simple current sensorless control for totem-pole boost converter is aimed to achieve superior power factor correction (PFC). In recent years, conduction loss and reverse-recovery issues have been improved by the advanced power devices, and thus the converter's efficiency and reliability are enhanced. Moreover, this converter topology has good potentiality for high-power applications. There are only two voltage sensors in both ac-side and dc-side for providing voltage information, which is an effective control strategy without current transducer. In addition, an equivalent single-switch model of totem-pole boost PFC converter is offered that is an efficient approach to analyze the converter's behaviors. Finally, some analytical results are given to evaluate the feasibility of the proposed current sensorless control method.
