Abstract
A power converter circuit includes a chopper circuit configured to receive an input voltage and generate a chopper voltage with an alternating voltage level based on the input voltage, an autotransformer including at least one tap, the autotransformer being coupled to the chopper circuit and configured to generate a tap voltage at the at least one tap, and a selector circuit configured to receive a plurality of voltage levels. At least one of these the voltage levels is based on the at least one tap voltage. The selector circuit is further configured to generate a selector output voltage based on the plurality of voltage levels such that the selector circuit selects two of the plurality of voltage levels and switches at a switching frequency between the two voltage levels.
