Abstract
A rectifier circuit having a power factor correction and providing a DC output is disclosed. AC power having an AC oscillation is supplied at two or more AC inputs. The rectifier circuit includes at least two power factor correction stages which are directly coupled to one or more of the AC inputs, wherein each of the power factor correction stages controls a flow of current through the one or more coupled AC inputs so that the power factor is optimized. The power factor correction stages are designed to operate during different half waves of the AC oscillation with respect to one or more of the AC inputs.
