Abstract
In a power-generator control apparatus, a control circuit intermittently controls the supply of a field current from a battery to a field winding of a power generator in normal mode so as to adjust power induced in an output winding of the power generator. The control circuit interrupts the supply of the field current from the battery to the field winding in transient mode when a transient voltage occurs. An energy absorbing circuit absorbs magnetic energy stored in the field winding independently of magnetic-energy consumption by a resistance of the field winding itself.

A power-generator control apparatus for controlling a field current supplied from a battery to a field winding of a power generator, the field current generating a magnetic field, the magnetic field inducing power in an output winding of the power generator, the power-generator control apparatus comprising:
- a control circuit configured to intermittently control the supply of the field current from the battery to the field winding in normal mode so as to adjust the power induced in the output winding of the power generator, the control circuit being configured to interrupt the supply of the field current from the battery to the field winding in transient mode when a transient voltage occurs;
- and
- an energy absorbing circuit configured to absorb magnetic energy stored in the field winding independently of magnetic-energy consumption by a resistance of the field winding itself.
