Current Transformer - an overview | ScienceDirect Topics an AC motor drive using this technique we therefore have a means of judging the motor current. In a DC drive this circuit is also applicable since the AC supply (L 1, L 2, L 3) to the controlled rectifier is also a measure of the motor current on the output of the converter.The current transformers also implement galvanic separation between power and control circuit.
