Definitions
- the present invention relates to a method for operating a
- Control device for speed control of an electric motor which control device comprises a frequency converter circuit and a power factor correction circuit and a microprocessor influencing these circuits.
- Control devices of the type in question are, for example
- the power factor correction circuit upstream of the frequency converter circuit serves to avoid the repercussions of the non-sinusoidal current consumption of the frequency converter circuit on the power supply network and, in particular, the requirements of the European one serving for this purpose To comply with standard EN 61000-3-2.
- EP 697 569 B1 discloses a control device for controlling a compressor motor of an air conditioning system, the operating mode described there, however, being based on essentially constant load requirements for the motor.
- the power factor correction circuit does contain an internal control circuit, which is provided to keep the output voltage constant; However, such a downstream control loop is not able to compensate for abrupt load fluctuations. In extreme cases, a brief drop in the output voltage of the power factor correction circuit can cause the motor to be weakened in the field, which results in the breakdown of the torque and thus the immediate standstill of the motor.
- the object of the present invention is therefore to provide a method for operating such a control device for regulating the speed of an electric motor, which avoids the disadvantages of the prior art shown.
- This object is achieved in that the power factor correction circuit is operated as a function of a changing torque requirement and the associated variable power consumption of the electric motor.
- DSP digital signal processor
- the power factor correction circuit (1) is set in a sufficiently short time (in the range of a few milliseconds) before the motor is started so that the motor is provided with the full power. This behavior is caused by an external intervention in the voltage control loop
- Power factor correction circuit (1) realized. As soon as the engine has started, the torque requirement drops drastically. In order to avoid overvoltage, the control loop is intervened again to master load shedding.
- the speed control loop of the frequency converter circuit (2) is intervened and the maximum possible manipulated variable of the speed controller is reduced.
- the power can thus be limited to the maximum possible power of the power factor correction circuit (1), so that the same cannot be overloaded.
- the voltage requirement of an asynchronous machine increases linearly with the speed.
- the power factor correction circuit (1) only supplies as much voltage as is necessary to operate the motor. The losses in the control unit can thus be reduced.
- the power factor correction circuit (1) enables operation at mains input voltages that are below the rated voltage of the motor. This means that the device can be operated over a wide input voltage range (in this case, for example from 85 volts to 265 volts). A synchronization of the switching times of the power semiconductors of these two circuit parts is possible by means of the common DSP (3) provided for controlling both the power factor correction circuit (1) and the frequency converter circuit (2).
- Such a synchronization can, on the one hand, make the measured value acquisition by the DSP much less sensitive to interference, and on the other hand, the synchronization also has a positive effect on the electromagnetic compatibility (EMC) of the control unit by significantly reducing the unwanted radiation of electromagnetic waves.
