Is opened, the contacts 10 and 15 are short-circuited, and the ordinary power is supplied to the converter 100 and the three-phase transformer 103.
At this time, the DC voltage rectified by the converter 100 and smoothed by the smoothing capacitor 11 is applied to the first inverter 1

The elevator will be driven. At the same time, if the power supply suddenly stops during the normal operation as described above, the contacts 10 and 15 are opened, the contact 17 is short-circuited, and the output voltage of the battery 105 is
8 to the first inverter 101 side, and then to the DC side of the second inverter 104 to change the output voltage of the battery 105 from the second inverter 104 to a three-phase AC voltage. The output is output to the phase transformer 103, and thus the power is supplied to the control circuit 102.

In operation, regenerative power is generated from the induction motor (M), and the regenerative power is fed back to the DC side via the first inverter 101 to increase the DC side voltage.

The overvoltage suppression is performed by the control algorithm of the control circuit 102 so that the induction motor is not operated in the regenerative region, so that the induction motor is not operated in the regenerative region. In some cases, the diode 18 connected between the battery 105 and the DC side is destroyed by the high voltage raised by the regenerative electric power, so that an expensive battery is eventually destroyed.

The present invention has been made in view of such a conventional problem, and does not perform complicated and unreliable overvoltage suppression, but can prevent an elevator speed reduction due to a low battery voltage and can improve the reliability. The purpose of the present invention is to provide an emergency operation device.
