Abstract :
A circuit topologies family of single-stage parallel uninterruptible AC/DC converter with high power factor are presented. The topology includes four sections, i.e. full bridge rectifier, parallel converter with power factor correction(PFC), uninterruptible power supply and fast output voltage regulation. The converter has lots of advantages such as: single stage power conversion, uninterruptible power supply, high power factor, electrical isolation between battery and AC input, fast regulation speed of the output voltage. The operational modes, control principle, and design method of key parameters are proposed. A prototype of 1kW is designed. The performance of the proposed scheme is verified through the experimntal result.
