Electric generation control device of electric generator for vehicle

An electric generation control device of an electric generator having a stator winding and a field winding, the electric generation control device comprising:

• excitation switching means, composed of a pair of arms in four arms forming a H bridge circuit, configured to perform ON and OFF switching between the field winding of the electric generator driven by revolution of an engine and charging means supplying a current to the field winding;
• regeneration switching means, composed of another pair of arms in the four arms forming the H bridge circuit, configured to charge the current flowing in the field winding to the charging means during OFF state of the excitation switching means;
• and
• means configured to perform, as ON and OFF switching control for the electric generation of the electric generator, one arm of a pair of the arms forming the excitation switching means or the regeneration switching means when another arm of this pair falls in a short circuit failure.
