Evaluation of reactive and effective alternator current components - using phase discriminator with peak transformers in MOS circuit

摘要

The circuit is for evaluation of the reactive and effective components of an alternator current and consists of a MOS-circuit discriminator, operational amplifier shaping circuits, resistors, diodes, and a capacitor. The phase discriminator uses peak transformers for separation of the direct components of the pulse instead of the conventional use of diode or transistor circuits. The output of the evaluation circuit is drawn from three MOS switches and taken to a common terminal of the inverting input of an operational amplifier, which has a feedback capacitor and feedback resistor connected in parallel.
