Perfect Power Output Section

The HIVERT general MV VFD adopts the power cells connected in series and voltage overlapping method (i.e. Power cells multi-level cascade technology), it can output the perfect PWM sinusoidal waveform (see Figure 2 and Figure 3). It has the following advantages:

1. No need for the additional output filter

2. Directly driving general synchronous or asynchronous motor

3. No de-rating operation on the motor

4. No dV/dt stress on the insulation of motor and cables

5. No torque ripple, extending service life of motors and mechanism

6. No cable length restriction within the acceptable voltage drop.

The general MV VFD has the following protection functions and features:

The RMVC 5100 provides speed and/or torque control for Solution for a wide range of industries
motor-driven applications in the medium and high power
range from 200kW to 14 MW at motor voltages from 3.0kV
to 13.8 kV.
It is available with air cooling in the lower power range and
with optional water cooling in the medium to high power
range. RMVC 5100 drives are also available mounted
within a customised container, with self-contained sealed
cooling systems, providing the highest IP class ratings for
hostile environments as well as providing greater
convenience and ease of installation and commissioning.
