摘要:
According to one embodiment, a device includes a power management module to which a power is supplied from an external power source, a power source supply circuit to which a power is supplied from the power management module via a first input terminal, a latch circuit configured to be operated by a power supplied from the power supply circuit or a power supplied via a second input terminal, a circuit configured to output a logic signal that sets a shutdown signal output from the latch circuit to a third input terminal, and a logic communication circuit to which a logic signal is supplied via the third input terminal and which supplies the logic signal to a forth terminal of the larch circuit. The shutdown signal output from the latch circuit is set to an predetermined level when the logic signal is set to a second level from a first level.

A power generator according to an embodiment includes a rotor shaft, a slip ring, a detecting shaft, and a position sensor. The rotor shaft through which wires from a propeller are inserted rotates with the propeller. The slip ring is coupled to the rotor shaft at one end. The detecting shaft is provided at the other end of the slip ring and rotates along with the rotor shaft. The position sensor detects the rotational position of the detecting shaft, thereby detecting the rotational position of the propeller.

A power generator according to an embodiment includes a propeller, a position detector, and a pitch controller. The propeller includes a plurality of blades whose pitch angle is changeable, and is rotated by a fluid. The position detector detects the rotational position of the propeller. The pitch controller performs pitch control processing for changing the pitch angle depending on the position of each of the blades specified by the rotational position of the propeller.
