Thermal protection scheme for high output vehicle alternator

摘要

A system and a method for thermally protecting a high output vehicle alternator are provided. The high output vehicle alternator includes a duty cycle control system. The duty cycle control system includes an alternator temperature signal generator and an alternator rotor speed signal generator in communication with an alternator having a speed limit and a temperature limit. The duty cycle control system regulates the field current supplied to the alternator based on the temperature and rotor speed signals.
