Abstract
An electrical device includes a plurality of single-phase power cells electrically connected to receive power from a source and deliver power to a load. The single-phase power cells include a first rank of regenerative power cells and a second rank of non-regenerative power cells. Each non-regenerative power cell may include an inverter bridge, a capacitor set electrically connected across terminals of the inverter bridge, and a three-phase bridge rectifier electrically connected across the terminals. The non-regenerative power cells may provide reactive power when the plurality of cells are used for braking of a motor.
