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 17):
A method for controlling operation of electrical switches of an unfolding bridge in an inverter configured to convert an input direct current (DC) waveform from a DC source to an output alternating current (AC) waveform for delivery to an AC grid, wherein the inverter comprises a transformer and a DC-AC inverter electrically coupled to the transformer, an active filter electrically coupled to the transformer, and an AC-AC converter, wherein the AC-AC converter comprises a half-bridge circuit electrically coupled to the transformer and an unfolding bridge circuit electrically coupled between the half-bridge circuit and the AC grid, the method comprising the steps of:\n determining a phase of the AC grid voltage; and generating a set of signals for actuation of the electrical switches of the unfolding bridge circuit based on the determined phase, whereby:\n when a voltage across the AC grid is positive during a first period, first and fourth electrical switches are on and second and third electrical switches are off; \n when the voltage across the AC grid is negative during a second period, the first and fourth electrical switches are off and the second and third electrical switches are 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, second, third, and fourth electrical switches are off.
