The equipment which is to feed and draw back A.C. current in traction applications. There is a transformer the primary of which is connected to a H. V. supply via protection equipment. The secondary is connected to a rectifier group, with terminals connected to the traction equipment. An inventor is connected to the connections by an inductive assembly and a resistive one. There is also an auto-transformer to raise the voltage between the invertor output and the secondary of an adaptor transformer. Current can be returned to the A.C. supply system as necessary. |
