Abstract:  A new single-switch three-phase AC-DC boost converter is used to achieve a high power factor and low line current harmonic distortion. The single switch is used so that the voltage stress is reduced thereby switching losses are also low. PI voltage controller is used to generate the gate pulses for the switch. Based on the control scheme, the output voltage is found to be balanced, THD is also reduced and the unity power factor is also achieved.

Keywords: ICS, PI, Power Factor, Total Harmonic Distortion (THD), Power Factor Correction (PFC).
