dv/dt filter (for 400V class only)

On systems that run 400 V class general-purpose motors by voltage-type PWM system invertersusing ultra high-speed switching devices (e.g. IGBT), surge voltage, that is dependent on cablelength, cable laying methods, cable constants, and other factors, sometimes causes theinsulation of the motor winding to deteriorate. For this reason, measures for suppressing surgevoltage are performed by installing a DC reactor or surge suppression filter on the inverteroutput end where the insulation-reinforced motor is used.
