Patent GB-1335475-A (GB)
Title: Voltage regulator systems
IPC: H02J7/16
Filed: 1971-08-19
Abstract: 1335475 Automatic voltage control GENERAL MOTORS CORP 19 Aug 1971 [24 Aug 1970] 38941/71 Heading G3R A voltage regulator circuit for charging a battery includes an alternator with a rectified output and a field winding connected in series with a controlled semiconductor switching device. A first voltage sensing circuit for controlling the switching device is connected across the battery terminals, and a second sensing circuit is connected across the field winding in order to regulate the circuit if the first sensing circuit is disconnected from the battery, the second circuit being actuated by a semi-conductor switch connected to the battery lead. In the system shown, a motor vehicle alternator 10 has a field winding 14 and output windings 12 connected across a battery 32 through a diode bridge 22. Further diodes 42 provide D.C. for the winding 14 which is connected to a transistor switch 36, the conductivity of which is determined by a voltage regulator circuit 34 comprising a first voltage sensing circuit 48 and a second sensing circuit 82, 84, 86. The circuit 48 is connected to the battery by a lead 50 and includes resistors 54, 56, capacitor 60, and temperature responsive resistor 58. In normal operation, the input voltage to the battery is sufficient to turn on a transistor 92 which prevents a Zener diode 90 from breaking down. Thus the second sensing circuit is inoperative and the first circuit 48 controls a transistor switch 64 through a Zener diode 72 and thus determines the switching of transistors 36 to regulate the voltage supplied to charge the battery. If the charging lead 30 becomes disconnected, the circuit 48 senses only the battery voltage which is insufficient to break down the Zener diode 72. Hence, control is taken over by the second sensing circuit. Since the transistor 92 is biassed on by the battery voltage, a higher voltage than that normally used for battery charging is developed, but the Zener diode 90 limits the voltage to a safe value. Should the lead 50 be disconnected, the transistor 92 turns off, and the second sensing circuit through Zener diode 90 controls the transistor switches so that the battery is charged at the same regulated voltage as in normal operation. This voltage would also be produced if both leads 30 and 50 were broken, but then the battery would not be charged. An indicating lamp 102 in series with ignition switch 106 lights when the alternator is running below speed and under fault conditions. Transistors 64, 92 and Zener diodes 72, 90 may be fabricated on a monolithic chip, Fig. 2 (not shown).

The condensor 11 and the vehicle readiator 2 are both cooled by air driven by a fan 3. The rate of water flow through heat exchanger 6 is controlled by a valve 13 having a temperature sensitive element outside the heat exchanger. The heat eschanger 6 is also used for air heating by circulation therethrough of engine cooling liquid via a valve 7. During air cooling, such circulation is prevented as the water circulation pump 14 has a working pressure greater than that of the pump 4 in the engine cooling circuit. The system is controlled by solenoid and thermostatic valves 10, 12 respectively.
