When the PWM inverter directly drives the motor, it will generate a higher common - mode voltage of dv/dt, and thus generate bearing current and common mode leakage current and severe electromagnetic interference(EMIl). Due to the influence of the distribution parameters in the cable, voltage reflection occurs at the motor end, resulting in coil linsulation failure. The dv/dt filter reduces the attenuation rate of the motor cable transmissign line, minimizes the peak ~ voltage, and effectively reduces the high output voltage dv/dt of the IGBT converter.

Product application

 

Dv/dt filter is for protecting the motor. Due to the long running cable between the inverter and the motor, it will cause a peak voltage that has a devastating effect on the motor. The length of the cable depends on the number of switchings of the power semiconductor and the size of the motor. If the cable is as short as 2.5 meters, the peak voltage of the motor will exceed the rated value. If the cable is too long, the problem is even bigger. In this case, a dv/dt filter is required to protect the motor from the devastating effects of the peak voltage.

Output Reactor

It is installed at the output end of the inverter, which is used to limit the capacitive charging current of the inverter and the motor connecting cable, and inactivate the voltage rise rate of PWM wave output by the inverter. When the length of motor cable exceeds a certain value, it is recommended to insert a motor reactor between the inverter and the motor, which is used to compensate the recharging current of capacitor in case of the long wires. The maximum length depends on the rated value of the frequency converter and the type of the motor cable.

Input Reactor

The input reactor can be used to provide improved overload protection for the line power supply, and to reduce the current harmonic distortion produced by the inverter. Increase the power factor of input power supply, reduce the high harmonic, and restrain the surge of frequency converter in the power supply equipment

DC Smoothing Reactor

DC smoothing reactor is used in the rectifying circuit to restrain the ripple pulse component after rectification and make the rectified current continuous, so as to improve the output branch waveform and guarantee the normal operation of DC equipment. The smoothing reactor is used as the series reactor in DC machine supplied by the converter, in order to eliminate the DC link in the current and voltage DC link converter; It is supposed to decouple the converter components on DC side. The power converter on DC side has high pulse circuit feedback to reduce the difference value limit, so as to limit the ring current on the connection with ring current, at the same time, limit the the rising rate of current. The smoothing reactor adopts the iron core of TEM and TET or TPK air core reactor, depending on the requirements on electromagnetic induction.
