Abstract:
A power conversion apparatus having a converter, an inverter controlled by inverter controller, and an input power source fluctuation detecting and controlling circuit is proposed. The input power source fluctuation detecting and controlling circuit includes an input power source fluctuation detector and a converter failure detector to detect overcurrent and/or overvoltage of the converter. When both of the input power source fluctuation and the converter failure are detected, the converter is gate blocked, and the inverter continues its operation, and when the DC voltage become lower than a threshold voltage during the converter is gate blocking, the input power source fluctuation detecting and controlling circuit outputs an inverter control changeover flag to the inverter controller for switching a contents of inverter control.

Claim (Index 1):
A power conversion apparatus having a converter for converting an AC power to a DC power, an inverter for converting the DC power to an AC power controlled by an inverter controller, and an input power source fluctuation detecting and controlling circuit, the input power source fluctuation detecting and controlling circuit comprising:\n an input power source fluctuation detector; a converter failure detector to detect overcurrent and/or overvoltage of the converter; wherein, when an input power source fluctuation is detected by the input power source fluctuation detector and a converter failure is detected by the converter failure detector, the converter is gate blocked, and the inverter continues its operation, and when the DC voltage become lower than a threshold voltage during the converter is gate blocking, the input power source fluctuation detecting and controlling circuit outputs an inverter control changeover flag to the inverter controller for switching a contents of inverter control.
