Abstract
A circuit comprises a power tank, a pair of transformers and multiple loads. The power tank converts a DC input voltage to an AC voltage. The pair of transformers comprise a pair of primary windings and a pair of secondary windings and transform the intermediate AC voltage to an output AC voltage. The pair of primary windings are coupled to the power tank for receiving the intermediate AC voltage, and the pair of secondary windings provide the output AC voltage. The loads are coupled to the pair of secondary windings for receiving the output AC voltage. The pair of secondary windings are serially coupled to each other through the series-coupled loads to achieve current balance among the loads.
