Abstract :
A new single-phase single-stage power factor correction converter with a simple auxiliary circuit is proposed. Using parallel power processing, this converter can be operated in wide line and load changes while limiting the link voltage below 400 V. Experimental results show that the measured power factor and efficiency are about 0.98 and 81%, respectively, at rated condition and the auxiliary circuit to reduce the link voltage is effective
