Abstract
A PFC rectifier comprises a first converter having a first output capacitor and a second converter having a second output capacitor. The he first and second capacitors are coupled to each other to increase the output voltage of the PFC rectifier. Fore example the first or second output capacitors can be serially coupled to each other. At least one or both of the first or second converters comprise buck or buck-boost converters, including inverting or non-inverter buck converters. The first and second converters can also form a bi-directional ac-ac inverter.
