Abstract:
Various enhancements to grid-interactive inverters in accordance with embodiments of the invention are disclosed. One embodiment includes input terminals configured to receive a direct current, output terminals configured to provide an alternating output current to the utility grid, a controller, an output current sensor, and a DC-AC inverter stage comprising a plurality of switches controlled by control signals generated by the controller. In addition, the controller is configured to: generate control signals that cause the switches in the DC-AC inverter stage to switch a direct current in a bidirectional manner; measure the alternating output current; perform frequency decomposition of the output current; and generate control signals that cause the switches in the DC-AC inverter stage to switch current in a way that the magnitude of a plurality of unwanted current components is subtracted from the resulting output current.

Claim (Index 11):
The grid-interactive inverter of  claim 9 , wherein the controller is configured to select a new switching frequency and duty cycle for the switches of the DC-DC conversion stage based upon the ratio of the measured power of the direct current received via the input terminals to the measured power of the alternating current provided to the utility grid by perturbing at least one of the frequency and duty cycle of the switches in the DC-DC conversion stage and measuring the power of the resulting output alternating current to determine whether the perturbation resulted in an increase in the ratio of the measured power of the direct current received via the input terminals to the measured power of the alternating current provided to the utility grid.
