Three Port Full Bridge PFC Converter for Hybrid AC/DC/DC System with Fuzzy Logic Control

This paper proposes a single-phase AC-DC-DC converter circuit for charging and discharging batteries and powering loads. The battery is added to the proposed system to reduce the energy consumption caused by the primary AC input voltage. The article implies an AC-DC-DC system with a single-stage, three-port, full-bridge converter. Like a conventional single-phase inverter with H-bridge topology, the ac input is single-phase and operates on two legs. Consequently, each leg serves as both an inverter and a buck-boost converter. Furthermore, the converter only employs four switches and diodes to regulate the flow of electricity between the three ports. A thorough topological analysis and simulation results validate the proposed converter system’s benefits
