Abstract

913,978. Control of D.C. motors. SIEMENSSCHUCKERTWERKE A.G. July 28, 1961 [July 29, 1960], No. 27577/61. Class 38 (3). [Also in Group XXXV] In a motor control system three series arrangements of controlled rectifiers supply the motor from a three-phase supply [Fig. 2). Fig. 1 shows one of the high voltage series arrangements of controlled rectifiers 2, 3, 4, 5 which has one uncontrolled rectifier 6 at the upper end, a resistive (or resistive and capacitative) main voltage divider 8, 9, 10, 11, 12, a capacitative (or capacitative and resistive) control voltage divider 13, 14, 15, 16 connecting the ends of the series arrangement and the control electrode of each controlled rectifier except the lower end rectifier 2, which has an uncontrolled rectifier 7 in parallel with it, but with opposite polarity, and a control circuit 19. The capacitor 16 has half the capacitance of each of the equal capacitors 13, 14, 15. When the controlled rectifiers are blocking, the voltage dividers, together with the rectifiers 6 and 7, maintain the control electrode of each of the rectifiers 3, 4, 5 negative with respect to its cathode, whichever the direction of the voltage applied to the series arrangement. To switch the rectifiers on, when the upper end is positive, the rectifier 2 is triggered by the unit 19. Consequently, points 2a and 2b are connected, and rectifier 3 is triggered by the charge on capacitor 13. Similarly, rectifier 4 is triggered by capacitor 14, and so on. Diodes may be connected between the control electrodes and the control voltage divider, and there may be resistors connected between the control electrode and the cathode of rectifiers 3, 4, 5 (Fig. 2).
