In accordance with the concepts, circuits and techniques described herein, a converter circuit is provided having multiple half-bridge switching cells that can be selectively controlled using one or more switching patterns to convert a source voltage to a desired output voltage over wide voltage and power ranges while maintaining zero-voltage switching and/or zero-current switching. The converter circuit includes capacitive elements disposed between center switching nodes of the half-bridge switching cells and fixed potentials and a magnetic energy storage element coupling the center switching nodes of first and second half-bridge switching cells. A controller is coupled to the converter circuit to monitor, control and apply one or more switching patterns the half-bridge switching cells such that components of the half-bridge switching cells are switched having a minimal or zero voltage (or current) across them.

An accessory apparatus includes a housing, an apparatus connector, a plurality of auxiliary accessory interfaces, and an internal microcontroller. The connection connector is configured to mate with a corresponding accessory connector of a physical controller to electrically connect the internal microcontroller to the physical controller. Each auxiliary accessory connector is configured to enable a separate auxiliary user input device to operatively connect to the accessory apparatus and electrically connect with the internal microcontroller. The internal microcontroller is configured to: (1) receive an input control signal from an auxiliary user input device operatively connected to an auxiliary accessory connector of the plurality of auxiliary accessory connectors, (2) map the input control signal to a mapped control signal corresponding to a physical control of the physical controller, and (3) send the mapped control signal to the physical controller via the apparatus connector.
