ABSTRACT:
An alternating current (AC) generator of the type used in vehicular applications and driven by the vehicle engine has a stator winding and a field winding wherein the electrical resistance of the field winding varies as a function of temperature. An exciting current intermittently is allowed to flow through the field winding which induces a current in the stator winding. The output of the stator is rectified and used to charge the vehicle battery. The invention comprises inclusion of field winding current compensation apparatus which varies as a function of temperature to reduce undesired field winding current variations due to temperature which results in improvements of power output and stabilized generator driving torque.
