1. A power converter configured to convert DC power generated by a power generator into AC power, the power converter comprising:

  • a boost converter circuit configured to boost an output voltage of the power generator;

    an inverter circuit configured to convert an output voltage of the boost converter circuit into AC power and to interconnect the AC power with a power system;

    a buck converter circuit configured to perform power conversion of output power of the boost converter circuit and to supply resultant power to an internal load; and

    a controller, whereinthe controller is configured to;

    control the output voltage of the boost converter circuit to be higher than or equal to a first voltage value which is greater than the maximum value of AC voltage of the power system, in a case of interconnecting output power of the power generator with the power system via the boost converter circuit and the inverter circuit; and

    control the output voltage of the boost converter circuit to be lower than or equal to a second voltage value which is less than the maximum value of AC voltage of the power system, in a case of supplying output power of the power generator to the internal load via the boost converter circuit and the buck converter circuit.
