This paper analyzes a Digital Signal Processor (DSP) based One Cycle Control (OCC) strategy for a Power Factor Corrector (PFC) rectifier PERMED/COLOUR TREATED CONDITIONER with Common-mode Voltage (CMV) immunity.It is proposed a strategy that utilizes an emulated-resistance-controller in closed-loop configuration to set the dc-link voltage to achieve unity power factor (UPF).It is shown that if the PFC can achieve UPF condition and if the phase voltage is only affected by CMV, then phase current is free Soccer - Goalie - Gloves from CMV, as well as a lead-lag compensator (LLC) to average phase current.
