MX341 is a two phase sensed Automatic Voltage
Regulator and forms piece of the excitation structure for a
brush-less generator. Excitation control is derived from a
three-phase permanent magnet generator (PMG), to
isolate the AVR power circuits from the effects of nonlinear
loads and to reduce radio frequency interference on
the generator terminals. constant generator short circuit
current is another feature of the PMG system.

The AVR senses the voltage in the central generator
winding and controls the power fed to the exciter stator
and hence the main rotor to keep the generator output
voltage within the specified limits, compensating for load,
speed, temperature and power factor of the generator.

Soft start circuitry is included to provide a even
controlled build up of generator output voltage.
