Abstract: In case the operational power production level of a multi-phase DC-AC power converter decreases, a controller may be configured to determine that a switching leg or switching legs of DC-AC power converter are to be disabled based on a power criterion to reduce losses incurred by the DC-AC power converter. The controller may be configured to select one of more of the switching legs, based on a selection criterion, and disable the selected switching leg or switching legs so as to reduce phase imbalance or degradation of the switching legs.

Abstract: A single-phase power converter is disclosed for converting a direct current power source to an alternating current power across first and second output terminals, which may be connected to a split-phase system having a first-phase load connected between one phase and a second-phase load connected between the other phase. When the loads are not balanced, the single-phase power converter provides a differential current to compensate for the imbalance.

Abstract: A multi-level inverter topology is disclosed. A power converter circuit converts a DC source at its input to provide an alternating current (AC) at its output. The power converter circuit may have a controller operably attached to multiple series connections of switches. The controller may control one or more of the multiple series connections of switches to convert a DC input to provide multi-level AC voltages with DC offset across two terminals of the power converter circuit. The multi-level AC voltages with DC offset may then be converted by use of a plurality of series connections of switches to provide a single-phase AC voltage at a first output terminal with respect to at least one of a neutral potential, an earth potential, or a terminal of the power converter circuit.
