چکیده
Coupled inductors can effectively optimize the THD, loss, current ripple, and power density of multiphase interleaved totem-pole PFC converters. However, a coupled inductor will also worsen zero-crossing distortion process. This paper first introduces working principle converter with based on detailed analysis modes, then analyzes influence process caused by inductor. To eliminate inductor, an improved control strategy its digital realization method is presented through system model. Finally, validity correctness proposed circuit are verified in 7.7 kW converter.

متن کاملHigh-conversion-ratio Bidirectional Dc–dc Converter with Coupled Inductor
Abstract—In this paper, a high-conversion-ratio bidirectional dc–dc converter with coupled inductor is proposed. In the boost mode, two capacitors are parallel charged and series discharged by the coupled inductor. Thus, high step-up voltage gain can be achieved with an appropriate duty ratio. The voltage stress on the main switch is reduced by a passive clamp circuit. Therefore, the low resist...
