Abstract
There is provided a control apparatus for a photovoltaic inverter. The control apparatus includes a system voltage detector, a DC voltage detector that detects a DC voltage applied to the inverter, an output voltage deficiency detector that detects an output voltage deficiency of the inverter based on the system voltage and the DC voltage, an output-current detector, an output-current distortion detector that detects distortion of the output current based on a harmonic included in the output current, a MPPT controller, and an output-current distortion controller that performs control to set the DC voltage applied to the inverter to a voltage at a power point less than a maximum power point when the output voltage deficiency is detected and the distortion of the output current is detected.
