N2 - In this paper, a three phase isolated buck-boost derived power factor corrected (PFC) converter with a novel clamping circuit to limit the voltage spikes across the switches is proposed. The converter is operated in Discontinuous Conduction Mode (DCM) to achieve PFC at AC mains, thus the input current shaping circuit can be eliminated. It requires only one simple voltage control loop to regulate the output voltage, hence only one output voltage sensor. This makes the system cost effective, more reliable and robust. By using the proposed clamping circuit, the transformers leakage inductance energy is successfully captured in a clamping capacitor, and thereby it is fed to the load through a forward converter to improve the efficiency of the converter. The converter steady state operation and detailed design calculations are presented. The converter and its design is validated through the simulation and the experimental results.
