Abstract: A direct current/alternating current (DC/AC) inverter system includes a primary DC-DC converter that receives an input DC voltage and a secondary DC/AC inverter. The primary DC-DC converter includes a plurality of switching networks and a plurality of transformers having a plurality of primary windings and a plurality of secondary windings. Characteristically, the plurality of secondary windings is arranged in series to provide a first output and a second output. A resonant LC circuit is connected in series with the first output and the second output. A rectifier rectifies an AC voltage between the first output and the second output to form a first rectified output. The secondary DC/AC inverter receives the first rectified output or filtered output thereof and provides a high voltage AC output. A controller mediates switching of the plurality of switching networks.
