Effective Energy savings due to high efficiency* Multi-level PWM control – inverter loss minimized
* Eliminating output transformer loss
* Reduces harmonic loss of motor itself by less harmonic contents in output current
Over 97% of efficiency (Input trans. + Inverter)(Load test result: Efficiency of TMdrive-MVG=97.6%)
