EFFICIENCY

The efficiency of the system is influenced by many factors. In order to achieve good efficiency, the voltage

difference between inverter AC and DC must be taken into account. Lower voltage difference, means

better efficiency. The AC voltage is determined by the motor-generated voltage. This value is directly

proportional to the motor speed.

In addition, the AC current, the switching frequency, and the AC frequency have a significant effect on

efficiency.

We used an medium voltage EMRAX 228 motor with high 660 Vdc for efficiency measurement.
