Used as output reactors for the frequency inverter, dv/dt filters attenuate the inverter’s clock signal and edge steepness. This enables long shielded motor supply lines in the system. Harmful voltage spikes (dv/dt) are attenuated and this helps improve the system lifetime. dv/dt filters improve system reliability and ensure more Power Quality.
