In the elevator device normal running, when the car of elevator device is loaded with that the passenger is in step-down operation or is in the lift operations without any load, and when induction motor M when in regeneration range, operating during the power fail, in induction motor M, can produce regenerating power.So the regenerating power that produces can feed back to the circuit part of being operated by direct current (DC) by first inverter 101, and voltage is wherein raise.
In order to prevent device between the changer 100 and first inverter 101 owing to the voltage that raises damages, control circuit 102 can be connected transistors 13, and consumes regenerating power.
Yet; the common equipment that is used for the elevator device emergency operation unnecessarily needs overvoltage adjustment (retaining) parts such as control algorithm; so that induction motor is not driven, protect each device in the circuit part of inducing DC voltage thus during power fail.
In addition, consume circuit or overvoltage adjustment component when going wrong when relating to regenerating power, institute's bonded assembly diode can puncture owing to the high pressure that regenerating power raise between battery 105 and dc voltage circuit part, can cause this expensive batteries destruction thus.
Also have, during power fail, can be used for driving induction motor, make the actuating speed of elevator be set to inadequately to be high enough to and to be proportional to voltage/frequency (V/F) ratio that presets by the vdc that battery produced.
Therefore, first purpose of the present invention just provides a kind of equipment that is used for the elevator device emergency operation, and it can overcome the speed limit by regenerating power consumption and the caused lift car of low battery voltages.
