IMPLEMENTATION OF FAST RESPONSE CONTROLLER FOR BRIDGELESS BUCK CONVERTER WITH IMPROVED POWER FACTOR

Active power factor correction (PFC) converters are widely applied in power electronic equipment to meet the rigorous international input current harmonics standard like IEC 61000-3-2 limits. Commonly, the boost converter is the most popular option as the PFC front-end because of its simple topology, excellent current-shaping performance, easy control and low cost.
