Description

Features and benefits
Converts the rectangular PWM output voltage of
motor drives into a smooth sine wave with low
residual ripple
Elimination of premature motor damage caused by
high dv/dt, overvoltages, cable ringing, motor
overheating, and eddy current losses
Improves bearing life time because of bearing
currents caused by circulating currents
Reduces electromagnetic emissions and acoustic
noise levels
Eliminates pulse reflections in the motor cable

Typical applications
HVAC applications
Pumps
Ventilators
Conveyors
Compressors
Elevators
Cranes
Medium voltage applications, deployed in front of
the step-up transformer
Retrofit installations with motor drives
Motor drive with long motor cable
Motor drive with multiple motors in parallel
