Abstract:
Systems, methods, and articles of manufacture are provided wherein inverter topologies and inverter control employ primary and secondary windings with a half-bridge circuit and an unfolding bridge circuit positioned between the second winding and an AC grid. Certain topologies may employ control circuits for controlling the bridges suitable for a phase angle of the AC grid.

Claim (Index 1):
A multi-port inverter for converting an input direct current (DC) waveform from a DC source to an output alternating current (AC) waveform for delivery to an AC grid, the inverter comprising:\n a transformer; a DC-AC inverter electrically coupled to a first winding of the transformer, wherein the DC-AC inverter is adapted to convert the input DC waveform to an AC waveform delivered to the transformer at the first winding; an AC-AC converter electrically coupled to a second winding of the transformer, wherein the AC-AC converter is adapted to convert an AC waveform received at the second winding of the transformer to the output AC waveform having a grid frequency of the AC grid, the AC-AC converter comprising:\n a first set of electrical switches electrically coupled to a first terminal of the second winding of the transformer; \n a capacitor divider electrically coupled with the first set of electrical switches and to a second terminal of the second winding of the transformer; \n a second set of electrical switches electrically coupled to the AC grid; \n a first capacitor electrically coupled across the first set of electrical switches; and \n a sensor electrically coupled between the first capacitor and the second set of electrical switches, the sensor sensing the AC grid current; and \n an active filter coupled to a winding of the transformer, wherein the active filter is adapted to sink and source power with one or more energy storage devices based on a mismatch in power between the DC source and the AC grid.
