| Abstract |
The conventional single phase PFC converter can control DC voltage to steady standard value but control system is system is complex and expensive and has rapidity problems because of controlled by detecting DC voltage, AC voltage and current. In order to solve those problems, this paper proposes senseless PFC converter circuit. The proposed circuit can control the whole system by detecting AC voltage waveform And it directly controlled DC output voltage by the controlled voltage value Kd(Ed/Ea). The fluctuation ratio of DC output voltage is changed by the circuit characteristics These characteristics are confirmed by some experimental results. |
