As per international agency regulation (IEC 1000-3-2/EN 61000-3-2) and market expectation, it is important to reduce current harmonics in the AC line current drawn by SMPS/ UPS connected to AC Mains as source and also it is desired by the user to deliver maximum power output by achieving unity power factor. To achieve the above objectives in SMPS/ UPS, APFC is required to be implemented as front end power interface between SMPS/UPS and AC Mains source. This study explores low cost design solution - DSP based APFC for Industry involved in manufacturing/supply of SMPS/UPS.
