Control system for AC generator, e.g. for vehicle, has overvoltage circuit for controlling output voltage of alternating current generator on positive electrode side of magnetic field coil

摘要

The system has a magnetic field coil (102), generator coils (101) and a voltage control circuit (3) arranged on the negative electrode side of the magnetic field coil. An overvoltage protection circuit (7) for controlling the output voltage of the AC current generator is arranged on the positive electrode side of the magnetic field coil.
