Abstract
A micro inverter includes a synchronous bi-directional power converter and a controller communicatively coupled to the synchronous bi-directional power converter. The controller is configured to operate the micro inverter in a forward conduction mode when photovoltaic (PV) power is available and operate the micro inverter in at least one of a reverse conduction mode and a reactive power compensation mode when PV power is unavailable.
Claims20
A micro inverter comprising:
- a synchronous bi-directional power converter;
- and
- a controller coupled to said synchronous bi-directional power converter, said controller configured to:
- operate said micro inverter in a forward conduction mode when photovoltaic (PV) power is available;
- and
- operate said micro inverter in at least one of a reverse conduction mode and a reactive power compensation mode when PV power is unavailable.
A method of operating a micro inverter having a synchronous bi-directional power converter coupled to a direct current (DC) power source and to an electrical grid, said method comprising:
- synchronously operating, using a controller, the micro inverter in a forward conduction mode when photovoltaic (PV) power is available from the DC power source;
- and
- synchronously operating, using the controller, the micro inverter in at least one of a reverse conduction mode and a reactive power compensation mode when PV power is unavailable.
A controller for use in controlling a micro inverter, said controller configured to:
- operate the micro inverter in a forward conduction mode when photovoltaic (PV) power is available;
- and
- operate the micro inverter in at least one of a reverse conduction mode and a reactive power compensation mode when PV power is unavailable.
