Abstract
A system for supplying AC power from a DC power source, such as a photovoltaic array is disclosed. The system includes a converter and an inverter coupled by a DC link. Control methods and systems are provided to maintain the DC source voltage and the DC link voltage below the open-circuit voltage of the DC power source. During steady state conditions, the DC source voltage and the DC link voltage are maintained below the open-circuit voltage of the DC power source by controlling the output of the inverter. The DC link voltage is temporarily adjusted to allow for higher DC link transients when the DC power source is first coupled or re-coupled to the system. During conditions when the inverter is decoupled from the system, the converter is controlled to maintain the DC link voltage below the open-circuit voltage of the DC power source.
