Abstract :
Single-stage AC/DC power converters are an advisable solution to meet the regulations for low frequency harmonics (such as EN61000-3-2) at lower cost compared with the two-stage approach. The main challenge is the use of this type of converter in universal line voltage applications. In this paper, a single-stage AC/DC power converter capable of operating with a universal input voltage range is proposed. The main difference with other proposals is that the storage capacitor of this converter holds a voltage equal to the line voltage and it does not penalize the voltage stress on the circuit. An experimental prototype confirms this result
