Actual measurements of a 3.3 kV inverter

Variable speed operation of existing motors is possible

■ With Fuji Electric's unique multilevel PWM control, the output current waveform is almost a sine wave.
⇒Reduces motor torque ripple and prevents overheating during inverter operation.

■ Multilevel PWM control minimizes switching surge.
⇒Reduces stress on motors.
