1. A power conversion device comprising:
- input circuitry configured to be coupled to a power source or load, the input circuitry comprising at least one switching device or diode;
an output switch bridge configured to be coupled to a load or power source, the output switch bridge comprising at least four controllable switching devices arranged in a bridge configuration to control current output; and
a link stage comprising at least one reactive component configured for alternating current (AC) operation, wherein the input circuitry, output switch bridge and link stage are operative to regulate input and output currents and manage power mismatch between the power source and load.
