This paper introduces a novel active current injection circuit to mitigate harmonics and to amend the power factor of a three phase front-end uncontrolled rectifier. The high PF is achieved by injecting HF current, from the HF inverter, at the input of the front- end three-phase rectifier the inverter switches are in zero voltage switching. The front- end rectifier diodes are working in zero current transition. It results a current waveform is continuous and sinusoidal in shape and current harmonics reduced significantly . The fixed duty ratio with varying switching frequency, regulates the output voltage. The input current THD and power factor are 5.76 % and 0.99 respectively. The results are verified through PSIM simulation and compared with an experimental prototype of 2.5Kw.
