With these filters, we can take into account the requirements of the customers regarding, for example, motor voltage, earth capacitances, switch frequencies, du/dt behavior and voltage spikes to the motor as well as the cable to the motor (load).
These requirements guarantee ideal du/dt adjustment and smooth interaction between the frequency transformer, filter and motor, without increases in the temperature or asymmetrical effects. In many cases, it is also possible to dispense with additional cable shielding.
