ｌｔ［制御が行われる。First, when the output armature coil l cuts the magnetic flux of the permanent magnet field pole 2 driven by the engine 10, a three-phase alternating current voltage is generated in the coil 1. This three-phase AC voltage is rectified by a converter 3, and then converted to a DC voltage with less ripple by a ripple smoothing capacitor 4. This DC voltage is converted to AC by an inverter 5, and the required single-phase AC power is output from an output terminal 6. On the other hand, the output voltage detected by the cardiac pressure extraction transformer 7 is rectified by the rectifier 8 and fed back to the control circuit 9. and,
Through the bottom pressure limiting circuit in the control circuit 9, it is compared with the voltage setting value set in the automatic 1 pressure regulation circuit, and the sine wave pressure of the sine wave generation circuit is controlled so that the output voltage is constant.
