2 - POWER SUPPLY
Both the AREP & PMG excitation systems
are controlled by the AVR.
2.1 - AREP excitation system
With AREP excitation, the electronic AVR is
powered by two auxiliary windings which
are independent of the voltage sensing
circuit.
The rst winding has a voltage proportional
to the alternator main voltage (Shunt
characteristic), the second one has a
voltage proportional to the stator current
(compound characteristic : Booster effect).
The power supply voltage is rectied and
ltered before being used by the AVR
monitoring transistor.
The rotating switch should be in the AREP
position (see 3.2.3).

2.2 - PMG excitation system
With PMG excitation, a permanent magnet
generator (PMG) added to the alternator
supplies the AVR with voltage which is
independent of the main alternator winding.
These two excitation principles provide the
machine with a short-circuit current overload
capacity of 3 IN for 10 s.
The AVR monitors the alternator output
voltage by adjusting the excitation current.
The rotating switch should be in the PMG
position (see 3.2.3).
