Abstract:
A controller for an A.C. generator for a vehicle, comprising:batteries each of which is charged with electric charges on the basis of an output of generation of electrical energy of an A.C. generator having a field coil; voltage regulating means for regulating a current, which is caused to flow through said field coil, on the basis of the detection result of a voltage developed across the terminals of said batteries due to an output voltage of said A.C. generator into a fixed output value of the generation of electrical energy of said A.C. generator; and field current restricting means for detecting a current which is caused to flow through said field coil by means of a field current detecting resistor to restrict the current to a predetermined value in correspondence to the detection result, wherein said field current detecting resistor is a thick film printed resistor, and wherein each of said means other than said thick film printed resistor is an electronic circuit and the electronic circuits are configured in the form of an integrated circuit.
