Abstract
A power generation device includes: a power generator, a power conversion circuit, a first interruption circuit, a second interruption circuit, a first monitoring circuit which monitors an output current from the power generator to the power conversion circuit and outputs a first interruption signal when an absolute value of the output current exceeds a first predetermined value, and a second monitoring circuit which monitors a total value of output voltages of respective phases of the power generator and outputs a second interruption signal when an absolute value of the total value exceeds a second predetermined value. The first interruption circuit interrupts a connection between the power generator and the power conversion circuit in accordance with the output of the first or second interruption signal. The second interruption circuit interrupts a connection between three-phase coils and the neutral point in accordance with the output of the first or second interruption signal.
