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 3):
The grid-interactive inverter of  claim 1 , wherein the DC-AC inverter stage is an H-bridge inverter comprising four MOSFETs configured to receive PWM control signals from the controller, where the PWM control signals configure the MOSFETs to switch current in a bidirectional manner through an output filter connected to the output terminals of the grid-interactive inverter.
