  3. Alternator C A B

  4. AC Current • Rotor - Stator creates AC current • Since there are three Stator, three separate ac signal are created.

  5. Signal Conditioning (Alt. to Bat.) • Typical Alternator Cicuitry. • AC from each of the alternators stators are filtered to only receive Positive current.

  6. Alternator Rectifier • Signal from the alternator is rectified to form a positive pulsating signal.

  7. Voltage Regulation • Voltage variations are due to: • Mainly Engine RPM • Temperature • Voltage is regulated through the current driving the STATOR.

  8. Voltage at Alternator Rotor Voltage Control Input Regulator Field Current Input

  9. Close Enough To 12V DC • Current in not pure DC, it is a series of DC pulses at 12 Vdc. • But most equipment have internal filters to clean-up the incoming power.
