Abstract :
Isolated power factor correction converters expose several shortcomings such as: the presence of slow-recovery diodes on conduction path leading to conduction losses and complexity in sensing circuit. This paper presents a new topology named isolated dual boost bridgeless PFC converter not only to improve efficiency by discarding of the low-recovery diodes but also to simplify the sensing circuit methodology. Additionally, a laboratory prototype with 100-140 V input, 400 V/750 W output was built and verified to demonstrate the circuit feasibility in this study. The experimental results shown that the efficiency improved by using bridgeless converter concept.
