Abstract:
DC power for low power loads is provided for vehicles such as snowmobiles where the electrical system includes primarily AC power. DC voltage is provided for gauges and similar loads even though the peak value of the AC is below a desired level. Rectification and regulation of some energy from the alternator is used for supplying the DC power at a desired DC voltage that is above an alternator zero to peak value. A capacitor and a diode are connected in parallel from the alternator with rectifying circuit portions for supplying power to the DC load. A DC voltage monitor senses the DC voltage supplied to the DC load and prevents the DC voltage from rising above the desired voltage by controlling the first rectification, the second rectification, or both.
