Abstract: An electrical system comprises a battery charger which charges or otherwise provides electrical power to an electrical subsystem via a switched-booster circuit. A control device, included in the electrical system, operates a switch module to controllably bypass a voltage-booster circuit according to the voltage of the electrical subsystem and/or the electrical current through the switched-booster circuit. The electrical system may further include additional electrical subsystems and the control device may be further configured to control the voltage-booster circuit.

Abstract: A vehicle electrical system comprises a generator, voltage regulator, switch module, and control device. The generator includes a field coil and one or more stator windings coupled together via the switch module. The generator provides electrical current to one or more electrical loads. The voltage regulator maintains the generator output voltage at a constant voltage by varying the field current. The switch module may include low-power transistors. The control device monitors the field current, output voltage and stator current and applies control signals to the switch module to improve transient recovery due to sudden variations in the electrical load and increase system efficiency during normal operation.

Abstract: A vehicle electrical system comprises a generator, voltage regulator, electrical energy source, and control device. The generator provides electrical current to one or more electrical loads. Voltage variations are suppressed by storing electrical energy of the field coil of the generator in the electrical energy source, and by proving electrical energy from the electrical energy source to the field coil. The control device comprises a controller and a charging module operative to maintain the voltage of the electrical energy source at a predetermined voltage that is above the regulation voltage so as to reduce the generator output voltage variations.
