Control device for vehicle generator |
摘要 |
A control device for a vehicle alternator having a field coil, and an auxiliary permanent magnet. The control device includes voltage regulator, a generation-condition detecting circuit having a frequency sensor and a comparator for comparing a frequency of the output voltage with a reference value and a power source circuit for supplying electric power to the generation-condition detecting circuit when the output voltage becomes equal to or higher than a voltage that is generated without the field current. The generation-condition detecting circuit allows the voltage regulator to supply the field coil with controlled electric current only when the frequency of the output voltage is higher than the reference value.
