Power converting apparatus, control method therefor, and power generation system
First Claim
1. A power converting apparatus having a capacitor, comprising:
- a degradation determination section arranged to determine a degradation in the capacitor; and
an output suppressing section arranged to, when said degradation determination section determines the degradation in the capacitor, suppress a maximum output value in the power converting apparatus.

Abstract
In a solar power generation system having an inverter, if a smoothing capacitor in the inverter degrades, the operation of the inverter is interrupted, and a loss in the amount of power generation occurs inevitably. To prevent this loss, a degradation determination section (211) and output suppressing section (212) are provided in an inverter (2). If the degradation determination section (211) determines a degradation in capacitor (24), the operation of the inverter (2) is continued while suppressing the output current of the inverter (2) by the output suppressing section (212). In addition, a warning section (213) warns the user about the degradation in capacitor (24). With this arrangement, a solar power generation system capable of detecting a degradation in smoothing capacitor in the inverter (2) and appropriately operating the inverter (2) can be provided.
