  • Dual generator electrical system
    Patent number: 5254936
    Abstract: A motor vehicle power supply system for supplying current to the direct voltage loads on a motor vehicle. The system has two alternating generators which are driven by the engine of the motor vehicle. The output windings of the respective generators are connected to bridge rectifiers that supply current to a common motor vehicle direct current load. Each generator has a field winding and the current supplied to a respective field winding is controlled by a respective voltage regulator. The voltage regulators cause pulses of current to be supplied to the field windings. The system has a control circuit for controlling the pulse width of the current pulses supplied to the respective field windings such that the pulse width of the current pulses supplied to one field winding are substantially equal to the pulse width of the current pulses supplied to the other field winding.
