A controller for a wind power motor is provided to prevent an accident by breaking an output at a rear end and in the case of the occurrence of an error by previously testing the occurrence of an abnormal state. A voltage electronic circuit is composed of a separation amplifier, an output amplifier, and an amplifying circuit. An output voltage control circuit is connected to a rear end of the voltage electronic circuit, and is composed of an operational amplifier. A conversion circuit converts a three-phase current applied to a current supplying terminal. A current measuring circuit measures a current applied to the current supplying terminal. A safe switch connected to a front end of an output side is composed of a plurality of resistors and transistor elements, and excites a relay. A coupling circuit is connected to the output side, and is composed of a Schmitt trigger for obtaining a minimum voltage. A coupling circuit is connected to the output side, and is composed of the Schmitt trigger for removing an over voltage. |
