  • Power supply with power factor correction circuit
    Patent number: 9455624
    Abstract: A power supply with power factor correction circuit, comprises three rectifier modules, receiving a first phase voltage, a second phase voltage and a third phase voltage, and further including a filter, a single power factor correction circuit, and a working voltage convertor, wherein the filter receives one voltage and produces a filtering voltage to the single power factor correction circuit, the single power factor correction circuit then produces correction voltage to the working voltage convertor, and the working voltage convertor produces direct voltage; wherein the working voltage convertor can be the full-bridge phase-shifted convertor.
