With the development of modern power electronic, the technology of high voltage, big power frequency conversion speed regulation is getting more matured, many motor speed control mode has been changed in this direction. It adopts the phase shifting rectifier transformer as the core part of MV inverter, with nearly perfect sinusoidal wave, so there is no more the harmonic pollutions from LV converter. Moreover, you don’t need to install the distribution transformers in the system.
