摘要：
Systems, methods, and apparatus for supplying AC power to an AC power grid (140) from a DC power source (110), such as a photovoltaic (PV) array are disclosed. The systems include a converter (100) coupled to the DC power source (110) that provides DC power to a DC bus (125) at a DC bus voltage. The systems further include an inverter (130) coupled to the DC bus (125) for converting the DC power of the DC bus (125) to an output AC power. The systems further include a control system (150) configured to regulate the DC bus voltage of the DC bus (125) to operate at a variable DC bus voltage setpoint. The control system (150) adjusts the DC bus voltage setpoint based at least in part on the DC bus voltage and the output AC current of the inverter (130).
