Abstract
A step wave power converter includes a plurality of transformers each configured to receive a Direct Current (DC) voltage from one or more independently generated power sources. Each transformer comprising a primary winding and a secondary winding. A plurality of bridge circuits control different DC voltage inputs from one of the multiple independently generated power sources into the primary windings. One or more processors are configured to use a Phase-Shifted Carrier Pulse Width Modulation (PSCPWM) scheme to operate the bridge circuits in order to produce steps for a step wave Alternating Current (AC) output from the secondary windings.
