POWER GENERATION DEVICE

WIPO Patent Application WO/2023/199687

A1

A power generation device (1) comprises: a power generator (10); a power conversion circuit (21); a first interrupting circuit (23); a second interrupting circuit (24); a first monitoring circuit (25) that monitors output current flowing from the power generator (10) to the power conversion circuit (21) and also outputs a first interrupt signal when the absolute value of the output current exceeds a first predetermined value; and a second monitoring circuit (26) that monitors the total value of the output voltages of the respective phases of the power generator (10) and also outputs a second interrupt signal when the absolute value of the total value exceeds a second predetermined value. The first interrupting circuit (23) electrically interrupts the connection between the power generator (10) and the power conversion circuit (21) in accordance with the output of the first interrupt signal or the second interrupt signal. The second interrupting circuit (24) electrically interrupts the connection between three-phase coils (Lu, Lv, Lw) and a neutral point (N) in accordance with the output of the first interrupt signal or the second interrupt signal.
