Abstract
1,146,977. Switching circuits. MULLARD Ltd. 28 March, 1966 [18 May, 1965], No. 20969/65. Heading H3T. [Also in Divisions G3 and H2] A motor 11, 12, e.g. in an automatic washing machine, is energized from a full wave rectifier via a thyristor 24 which is triggered by the discharge of a capacitor 38 through a transistor 36 at a firing angle determined by the charging rate of the capacitor which is varied in steps by switched resistors 62, 63, 64 to provide, e.g. three speeds. The transistor collector and base are transformer coupled to provide a regenerative circuit and the triggering pulse is developed in an additional winding 35 on this transformer. The charging circuit supply is stabilized by a Zener diode 51, and the resistor corresponding to top speed 64 is a thermistor to limit the acceleration when this is selected. At the two lower speeds the charging rate of the capacitor is modified by the back e.m.f. of the motor in a diode/resistor circuit 4 so as to keep the selected speed constant. The charging rate is also modified by a current limiting circuit; this comprises a transistor 71 in series with the capacitor and normally fully conducting, but if the motor current becomes excessive the transistor is biased to become progressively less conductive.
