A three phase Vienna rectifier topology is proposed with a modified inductor and control models. The presented switched inductor structure works during the active switch turn on and turned off condition. So, voltage gain of the converter will be improved and the stress across the active switch due to voltage will be reduced. Here, (PSO) Particle Swarm Optimization algorithm-based control model is utilized to optimize the gain parameters of bidirectional active switch with required switching frequency. By using the capacitor voltage and the switched inductor current for gain adjustment through the light load and full load condition. So, the proposed topology reduces the (THD) Total Harmonic Distortion present in the inductor current and improves the power factor at both the continuous and the discontinuous conduction mode. The proposed circuit is applied using MATLAB/simulink and analyzed by comparing with feed forward compensation method and implemented in hardware using Field Programmable Gate Array (FPGA).
