Abstract

A series resonant circuit converts a DC input to an AC output. The circuit includes first and second series circuits connected across the DC input, but in opposite polarities. Each series circuit includes a switch, a transformer primary and a capacitor. Also within each series circuit, a diode is connected across the combination of the switch and transformer primary to provide limiting. The transformer primaries are connected together so that the switches are effectively in series. Singular and multiple transformer cores may be used in connection with singular and multiple secondaries to provide the AC output.
