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 9):
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 an AC-AC converter electrically coupled through a transformer to a DC-AC inverter electrically coupled to the DC source, the AC-AC converter comprising:\n a half-bridge circuit electrically coupled to a winding of the transformer; and \n an unfolding bridge circuit electrically coupled between the half-bridge circuit and the AC grid; \n wherein the AC-AC converter is adapted to convert an AC waveform received from the transformer to output the AC waveform having a grid frequency of the AC grid; and \n a controller having a processor and a memory wherein the controller is adapted to control the switching cycles of electrical switches of the unfolding bridge circuit, whereby:\n when a voltage across the AC grid is substantially positive during a first period, a first set of electrical switches is on and a second set of electrical switches is off; \n when the voltage across the AC grid is substantially negative during a second period, the first set of electrical switches is off and the second set of electrical switches is on; and \n during a third period comprising a blanking time period between the first and second periods when the voltage across the AC grid is approximately zero, the first and second, sets of electrical switches are off.
