Abstract

1309523 Battery charging systems TEXAS INSTRUMENTS Ltd 27 April 1971 11586/71 Heading H2H A system in which a battery is charged from a generator driven by an internal combustion engine by way of a triac is provided with means to protect the system should the battery be connected with the incorrect polarity. A battery 1 is charged from an A.C. generator 6 driven by the engine of a vehicle, a triac 14 being connected in between the battery 1 and the A.C. supply rectified by diodes 8-13. The gate electrode of the triac 14 is connected to the positive side of the battery by a circuit arrangement having a unijunction transistor 15, resistor 16, diode 17 and a switch 18 together with capacitors 20, 21 and a resistor 19. Closure of the switch 18 causes the emitter of the transistor 15 to assume the potential determined by the ratio of the capacities of the capacitors 20, 21 and then to rise slowly as the capacitor 21 is charged and the capacitor 20 discharged, both through the resistor 19. When the emitter potential reaches the threshold value of the transistor 15, the transistor becomes conductive and produces a pulse at the gate electrode of the triac 14. The triac then fires so that current can flow from the battery to the vehicle cicuits such as the ignition circuit 22 and other circuits 24, 28 controlled by switches 23, 25 respectively. The circuit components 20, 21, 19, 15 function to supply pulses repeatedly to the gate of the triac. When the vehicle engine has been started and the generator 6 is generating, the conductor 7 is maintained negative, this current will be able to flow through the triac 14 to charge the battery 1. If the battery 1 is disconnected the triac 14 becomes non-conductive and if the battery is connected incorrectly the capacitor 21 cannot charge because of the diode 17, thus no firing pulses can be produced at the gate of the triac. If the components 24 require to be powered by the battery 1 when the triac is non-conductive a changeover switch 26 may be provided. All the switches 18, 25, 26 may be mechanically ganged. In certain circumstances the switch 23 may be dispensed with.
