摘要： The present invention is a system, apparatus and method of a PFC rectifier having a programmable output voltage that does not incur a drastic penalty in the overall size or volume of the device, or a significant degradation in efficiency. The PFC rectifier of the present invention may incorporate a two-stage solution for output voltage regulation. The present invention provides a topology of a small-size/volume PFC rectifier with a variable (i.e. programmable) output voltage and a complementary control method. The two-stage system of the present invention incorporates a smaller and lower cost capacitor than the bulky size and costly energy storage capacitors required in conventional prior art. The present invention also achieves tight output regulation. The two-stage topology of the present invention further achieves on-line efficiency optimization and significantly reduces the volume of the downstream stage over the prior art examples through dynamic adjustment of the downstream stage supply voltage.
