POWER CONVERTER AND ITS CONTROL METHOD, AND POWER GENERATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To preclude a problem in a solar power generating system having an inverter that, if the filter capacitor of the inverter is deteriorated, loss of its generated energy is unavoidable because the inverter operation is interrupted. SOLUTION: If a deterioration judging part 211 judges that the capacitor 24 is deteriorated, the operation of the inverter 2 is continued while suppressing the output current of the inverter 2 by an output suppressing part 212. The deterioration of the capacitor is alarmed by an alarm part 213.
