Abstract
An AC/DC converting apparatus having first and second input nodes for receiving an AC input voltage Vin, a first pair of switches for coupling a first terminal of a first inductor to the first input node and ground, a second pair of switches for coupling a second terminal of the first inductor to an output node for providing a DC output voltage Vout and ground, a third pair of switches for coupling a first terminal of a second inductor to the second input node and ground, and a fourth pair of switches for coupling a second terminal of the second inductor to the output node and ground. The first pair of switches is turned ON when Vin is in a first portion having a first polarity, the third pair of switches is turned ON when Vin is in a second portion having a second polarity.
