They can control both synchronous as well as induction motors. Search Search term s Search. Dgnavert supply cos lohdr 1: This is the reason that no additional wiring is required.

To the top of the page. They have a fully controlled B6 bridge circuit on the line side and a B6 inverter circuit on the output side, which utilizes the principle of interphase commutation; this distributes the DC link current from the DC link reactors with a square waveform with frequency f to the motor winding.
