摘要： An electrical power conversion system for converting power from one voltage to another, especially for converting a higher-voltage, direct current electrical power system, such as a thirty-six volt to forty-two volt (36V-42V) direct current system for vehicles, into a voltage acceptable for powering lower voltage equipment, such as those using twelve volt to fourteen volt (12V-14V) DC vehicle electrical power systems is disclosed. The invention provides the ability to control the operating states of the loads by coupling a control signal to the vehicle's electrical power bus. The invention can take advantage of current or future DC-to-AC inverter or DC-to-DC converter technology and anticipated vehicle electrical systems to devise a electrical power conversion and control system meeting the needs of various vehicle loads.

摘要： An alternator system having an alternating current voltage source includes a rectifier coupled to the voltage source, a sensor coupled to the voltage source and an engine and a control circuit coupled to the voltage source, the rectifier and the sensor. The control circuit provides control signals to the rectifier and the voltage source. The alternator system further includes a fault protection controller coupled to an output of the alternator system and coupled to the control circuit. The rectifier operates such that the alternator system provides a load match which results in output power levels which are relatively high compared with output power levels of conventional alternator systems and the fault protection controller operates under fault conditions (e.g. load dump), and overrides the other controllers in the alternator system based on output voltage when a load dump occurs.

摘要： A three-phase alternating-current winding is constructed by forming winding phase portions into a Y connection. The winding phase portions are divided into first and second winding divisions. Outputs from the first winding divisions are rectified and output by a first rectifier, and outputs from the second winding divisions are rectified and output by a second rectifier. In addition, a magnetizing electric current supplied to a field winding is adjusted by a voltage regulator such that the output from the second rectifier becomes constant.

摘要： A generator system for providing power to communications equipment. The generator comprises an engine, an alternator, a rectifier, and a cable connected between the rectifier and the communications equipment. The engine converts fuel energy into rotation of an output shaft. The alternator is operatively connected to the output shaft to convert the rotation of the output shaft into a raw alternating current power signal. The rectifier generates a direct current power signal based on the raw power signal. The generator preferably comprises a controller for controlling the engine based on the load requirements of the communications equipment. A select switch may be provided to cause the controller to control the rectifier to generate the direct current power signal at first and second predetermined levels. The generator preferably comprises first and second sensors for generating first and second sense signals, where the controller controls the engine at least in part based on at least one of the first and second sense signals. The generator also may preferably comprise a converter operatively connected to the alternator for generating an auxiliary power signal having characteristics different from those of the direct current power signal.

摘要： An electrical voltage supply system includes an alternator having phase windings, it being possible to connect the alternator to a battery, and which is part of a first vehicle electrical system. The output of the alternator leads via a rectifier bridge and a voltage transformer operating as a step-up transformer to a second vehicle electrical system which has a markedly higher voltage and has usually no battery. To supply voltage to the loads of the vehicle electrical system which is operated at a higher voltage even during a standstill of the alternator, the alternator is then connected to the battery of the vehicle electrical system, and the higher voltage is obtained with the assistance of the step-up transformer, the step-up transformer operating in such a manner that is uses the alternator inductance as a choke.

摘要： A device for supplying voltage in a motor vehicle is described in which there is at least one generator that can furnish an generator-speed-dependent output voltage without voltage regulation. The at least one generator is preferably a three-phase alternator with a plurality of stator windings whose electrical connections are switchable at predetermined generator speeds by a control unit to provide the generator-speed dependent output voltage. In a following power control unit, this generator speed-dependent voltage is rectified by means of at least one controlled rectifier bridge and via assigned voltage converters is converted into a plurality of directly voltages of different magnitude. These direct voltages are supplied to the individual on-board electrical system components via electronic vehicle body power control system units. By optimal-efficiency triggering of the controlled rectifier bridges and additional safety and/or emergency provisions, the functional capability and power capability of the voltage supply unit are assured.

摘要： A mobile AC power source is described for generating AC electrical power that is powered by any rotational energy source such as a vehicle engine. The output of the mobile generator is sinusoidal but could have other shapes as well and is stable with variations in load and engine RPM. The AC output can vary in voltage from approximately 100 to 500 VAC RMS and in frequency from approximately 40 to 400 Hz. The mobile AC power source employs an alternator driven by the vehicle engine or any other rotational source and incorporates two stator windings and one rotor, or two stators, four windings and two rotors on a common shaft. The stator windings are insulated electrically from each other. AC output voltage is held constant by using the voltage produced by the alternator as feedback and controlling the alternator rotor current. A voltage step up circuit boosts the voltage from the alternator if it is below a threshold value as occurs at low engine RPM. A 2 quad PWM circuit encodes a low frequency sine wave onto a high frequency carrier. An output filter removes the high frequency carrier and produces a sine wave output. Also included is electronic protection against over current, over load, short circuit and thermal over load conditions.

摘要： A high efficiency automotive electrical system and method of control employing an asynchronous induction machine for performing both starting and generating functions. The induction machine is coupled to the engine through a bimodal gearset which operates as a reduction drive during the starting mode and as a direct drive during the generating mode. A computer-based controller responsive to the battery voltage and the speed of the induction machine maintains given voltage/frequency ratios during both starting and generating to provide efficient operation, and smoothly controls the transition between starting and generating modes. The vehicle electrical loads are supplied at one or more stable voltages produced by a load converter powered by the battery.
