<p>PURPOSE:To embody a control apparatus of a charging generator for a vehicle, wherein it can surely start and stop a power supply without being affected by a change in a working temperature so as to be interlocked with the on and off operation of a key switch. CONSTITUTION:When a key switch 5 is closed, diodes 365, 364, 363 are set to continuity, a transistor 370 is set to continuity, and a transistor 31 is set to continuity. A voltage Vcc is generated by a diode 33, a comparator 366 is set to an operatable state, a transistor 13 is set to continuity, and a charging display lamp 6 is turned on. The voltage level of a terminal L becomes larger than the voltage level VR of resistances 368, 367, the output of the comparator 366 is set to an 'H' level, and a transistor 361 is set to continuity. Even when a transistor 370 is cut off, the voltage Vcc is supplied stably because the transistor 361 is set to continuity. When the key switch 5 is released, the charging display lamp 6 is turned off. The voltage level of the terminal L becomes smaller than the voltage VR, the output of the comparator 366 is set to an 'L' level, the transistors 361, 31 are cut off and the power-supply voltage Vcc is lowered to a zero level.</p> |
