du/dt output filters, dv/dt filter reactors

V&T EcoDriveCN® du/dt output filters reduce the voltage rise rate of inverter output voltage and limits the peak voltage, protecting the motor winding.

Using V&T EcoDriveCN® du/dt filters, which consist of a reactor and capacitors, have a number of benefits. They increase reliability and help achieve lower operating temperatures. All this will increase the lifetime of the electrical motor.

V&T EcoDriveCN® du/dt filters reduce the dU/dt values on the motor terminal phase-to-phase voltage, which is an issue that is important for short motor cables.

Compared to V&T EcoDriveCN® sine-wave output filters, V&T EcoDriveCN® du/dt filters cut off frequencies above the switching frequency. Having small inductance and capacitance, the price of V&T EcoDriveCN® du/dt filters is lower.

Features of V&T EcoDriveCN® du/dt output filter range include:

• Reduce du/dt stresses


• Motors can be fed through long cables


• Lower the magnetic interference propagation on surrounding cables and equipement


• Enhancement of the system efficiency


• Reduction of EMI, increased EMC performances


• Increase the system reliability

V&T EcoDriveCN® dv/dt filter is designed to reduce dv/dt and peak voltages to motors fed from a wide variety of PWM inverters.

Using V&T EcoDriveCN® du/dt filters, which consist of a reactor and capacitors, have a number of benefits. They increase reliability and help achieve lower operating temperatures. All will increase the lifetime of the electrical motor.
