This paper presents a one stage circuit topology for a double buck chopper type single phase PFC converter with active power filtering function in a utility AC grid side and DC output power quality, which can realize much smaller in reactor size and lighter in its weight, along with two unique channel control schemes. The main advantageous point of the newly-proposed PFC converter includes that the...
In this paper, a novel common-source type boost-forward single-stage PFC topology was proposed. By adding a second wind to the transformer, and using two active-clamp switches connected in common-source type, an active-clamp ZVS (zero voltage switching) could be obtained with a simple PWM control and output voltage feedback. The proposed topology was experimentally verified through the construction...
