Even in applications where motor cable length is substantial, dV/dt filters reduce the peak voltage, prolonging the life of the motor. They accomplish this by cutting off frequencies above the switching frequency. With small inductance and capacitance, dV/dt filters are a more cost-conscious solution than (but not a substitute for) sine wave filters.
• Greater motor longevity through lower dV/dt stress
• Reduced transmission of electromagnetic interference to surrounding cables and equipment
• Trouble-free operation
