An apparatus includes a plurality of output filters. Each output filter is to provide a respective output power signal at a respective voltage level. The apparatus also includes a plurality of power multiplexers. Each power multiplexer corresponds to a respective one of the output filters and each has a respective output coupled to an input of the respective one of the output filters. Each of the power multiplexers has a plurality of inputs. The apparatus further includes a plurality of power cells. Each power cell is coupled to a respective input of at least some of the power multiplexers. In addition, the apparatus includes a control unit to control the power multiplexers to selectively establish a connection between the output of each power multiplexer and at least one of the inputs of the power multiplexer.
