ABSTRACT:
A circuit used to convert a DC input to an AC output includes a pair of series circuits. Each of the series circuits is in parallel with the DC input and includes a switch and a transformer primary. A capacitor couples the two series circuits, and is attached to each series circuit at a node between the respective transformer primary and switch. A secondary on the transformer provides the AC output. Optionally, multiple transformers may be utilized. Similar topologies may be used for rectification instead of inversion.
