Abstract
1,067,777. Automatic current control. SOC. ANON FRANCAISE DU FERODO. July 3, 1964 [July 3, 1963], No. 27617/64. Heading G3R. A load such as a motor M is supplied from a D. C. source B over a switching device 11 which may include controlled diodes and which is controlled by a bi-stable circuit BI to maintain the load current at a desired value. A voltage Us proportional to the load current is applied, together with a desired reference voltage Ud, to a comparator transistor 12, and the resulting error signal is applied by way of an amplifying transistor 16 and a capacitor 19 to the circuit BI which switches to a first state and produces an output pulse on terminal 21; this pulse is applied over a pulse-shaper 23 to the input terminal EA of the device 11 which is thereby rendered conductive. When the load current reaches the desired value, the error signal becomes zero whereby transistor 12 becomes non-conductive allowing transistor 16 to conduct and discharge capacitor 19; this causes circuit BI to switch back to its second state, producing on terminal 22 a pulse which is applied over pulseshaper 24 to the terminal ES whereby the device 11 is rendered non-conductive. The switching of device 11 is thus automatically controlled in a manner to maintain the load current at the value set by the voltage Ud. A network constituted by a diode 28, a capacitor 29 and resistors 26, 27 is associated with the capacitor 19, the arrangement being such as to establish a maximum limit for the conduction period and a minimum limit for the non-conductive period of the device 11.
