Abstract

Power factor correctin technique is an effect active to eliminate the harmonic pollution of power system. A single-stage power factor corrector basic on clamptive technique is presented in this paper. PFC and AC/DC power conversion is manipulated in one stage circuit. Due to the adoption of high frequency transformer, the electrical isolation between input and output sides can be realized. The voltage stress of each switch is reduced due to the active clamp circuit. By using soft-switching techniques, the bridge devices and the clamp switch could achieve ZVS (Zero-Voltage-Switching). Because of the characteristic of the structure, there is big current peak in the input inductor when the corrector starting-up. The scheme of soft starting-up is introduced, which made the starting-up process smoothly. Experimental results show that this converter has a good effect.
