A photoconductor charging system for use with an image forming device. The image forming device may include a plurality of image forming units transferring toner particles to a media substrate and each of the plurality of image forming units including a photoconductive unit and a corresponding charging unit positioned to charge the photoconductive unit. Generally, an alternating current power supply may be coupled to one or more of the charging units and supply a voltage thereto. The alternating current power supply may include a switching mode amplifier. In one embodiment, the switching mode amplifier is a class D amplifier. The charging system may further include a filter to filter an output of the switching mode amplifier. The filter may include a low pass L-C filter. The switching mode amplifier may operate a transistor output bridge between on and off states to improve amplifier efficiency.
