Abstract
An AC/DC converter that converts an AC input voltage Vin to a DC output voltage comprises an inductor, a capacitor selectively coupled to the inductor, a plurality of switches, and a controller. The controller configures the plurality of switches, inductor, and capacitor to operate as a buck converter during times when Vin>Vout and to operate as an inverting buck converter during times when Vin<−Vout. The controller modulates the duty cycles of the plurality of switches to regulate the DC output voltage Vout to the desired, constant output level.
