Abstract

1, 083, 988. Automatic current control. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Feb. 17, 1965 [Feb. 17, 1964], No.6851/65. Heading G3R. [Also in Division H2] A rectifying arrangement comprises two series-connected single phase bridges 4, 5, each consisting of two controlled semi-conductor rectifiers 4À1, 4À2, and two diodes 4À3, 4À4, the common junction of the controlled rectifiers being connected to an A. C. terminal. As shown the arrangement feeds a motor 6 in a selfpropelled vehicle. To effect control a measure of the actual current is detected by a current transferred 8 and fed to comparators 14, 15, to which a measure of the desired current I is also fed. Error signals from the comparators are fed via regulators 11, 12 to pulse generators 9, 10 controlling the bridges 4, 5, respectively. The value of the actual current fed to the two comparators are slightly different, that to comparator 12 being say 2% greater. In this way since the desired current I is common, the bridge 4 is controlled throughout its full range before the bridge 5 is controlled.
