摘要:
Compact integrated battery packs for hybrid vehicles are fully integrated with an on-board cooling system and include both the battery cells for supplying a primary voltage, such as powering a belt-driven starter generator (BSG) unit for engine start/stop, as well as a direct current (DC) to DC converter for stepping down the primary voltage to a secondary voltage for powering low voltage components and/or recharging a lead-acid battery. The on-board DC to DC converter decreases packaging size and eliminates the need for an alternator, which further decreases packaging size. Primary and secondary voltage output ports can also be implemented for quick and easy connection to other components. Configurations include single-layer and dual-layer arrangements with integrated air or liquid cooling for placement in or beneath a trunk of a vehicle, behind or beneath seats in a cab of a pickup truck, and/or beneath a vehicle.

An alternating current generator for motor vehicles having an extremely small power loss and which can be simply cooled includes a power converter having at least either high side semiconductor power elements or low side semiconductor elements. The high side power elements connect an output terminal of the armature coil to a high potential terminal of the battery; the low side semiconductor power elements connect an output terminal of the armature coil to a low potential terminal of the battery. The power converter converts the alternating current generated voltage of the armature coil into a direct current voltage to supply electricity to the battery. An exciting current controller includes a switching transistor for controlling an exciting current to a field coil. Either or both all the semiconductor power elements in the power converter or the switching transistor in the exciting current controller is formed of SiC material, which is a compound of Si and C, having a resistivity smaller than that of pure Si.

摘要:
To ensure an optimal supply of energy to the electrical system from a motor vehicle three-phase alternator, the excitation current is increased above the rated excitation current when the alternator rotates at low speeds, reduced at medium rotational speeds and increased again above the rated excitation current at high rotational speeds. As the temperature in the regulator itself is measured and the regulator is fastened to an alternator component which becomes particularly hot, the moment at which the alternator reaches a maximum permissible temperature can be ascertained in time. The excitation current is then reduced sufficiently for the maximum temperature not to be exceeded.

Für einen Spannungsregler für Generatoren von Kraftfahrzeugen wird vorgeschlagen, die Spannungsreglerschaltung in der Art einer Hybridschaltung auf einer sandwichartigen Trägerplatte anzuordnen. Dabei weist die Trägerplatte einen gut wärmeleitenden, metallischen Kern auf und ist mit einem isolierenden Überzug versehen, auf dem wiederum die Leiterbahnen der Hybridschaltung aufgebracht/aufgedruckt sind.

Magnetic bodies (9, 10) for reducing electromagnetic wave noises are mounted to a battery voltage supplying terminal (BR terminal) (11) for supplying of an electric source power for the operation of circuits to an IC chip of a regulator or an internal electric source line (21) for connection of the terminal to the regulator chip (3). The magnetic bodies are attached to an IG ON terminal (15) for inputting into the regulator chip (3) a voltage signal caused by opening and closing of an ignition switch (6) or to an IG ON detection line (23) for connection of the terminal to the regulator chip (3). A bypass capacitor (8) is connected to a battery voltage sensing terminal (11) (S terminal) for inputting a change of battery voltage into the regulator chip (3), or to an internal battery voltage detection line (22) for connection of the terminal to a switching transistor control circuit unit (31).
