The present invention concerns a device that combines the functionality of an inverter and a bi-directional converter. The device provides, on a number of identical channels, transformation of a DC voltage source of a given level to a filtered DC voltage of another level. The inverter and bi-directional converter of the present invention also has the capability to invert a DC power input to thereby supply, on an AC output, AC power to an AC load, such a fluorescent light. The DC voltage sources at the inputs of inverter and bi-directional converter may act as sources of DC power or sinks of DC power depending on the voltage level of each input and a winding ratio between the channels. Passing from being a source to a sink of DC power is performed smoothly and without interference with the operation of the AC load.
