<p><P>PROBLEM TO BE SOLVED: To provide a vehicle power generation controller, which realizes the stability of output voltage of a vehicle AC generator and the stability of engine rotation, has a simple structure and reduces the cost. <P>SOLUTION: The vehicle power generation controller 2 is provided with MOS-FET 201 intermitting exciting current supply to excitation winding 102, an exciting current detecting circuit 207 detecting an exciting current flowing in excitation winding 102 and a power generation voltage-exciting current control circuit 206 controlling the exciting current for limiting the exciting current flowing in an excitation winding 102 and performing controlled excitation for limiting an acceleration of a driving duty of MOS-FET201 at the time of controlling the output voltage of the vehicle power generator 1 to a first setting value Vreg. The power generation voltage-exciting current control circuit 206 cancels exciting current control when the output voltage of the vehicle power generator 1 becomes lower than a second setting value VL1 lower than the first setting value Vreg and cancels controlled excitation control when it becomes lower than a third setting value VL2 which is still lower. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
