1,079,259. Firing thyristors. LE MATERIEL ELECTRIQUE S.W. Nov. 4, 1964 [Nov. 19, 1963], No. 45027/64. Heading H3T. [Also in Division H2] A plurality of controlled rectifiers such as R are fired simultaneously by unidirectional pulses derived through rectifiers D1, D2 from a highfrequency oscillator 2 and switched by transistors T1 controlled by a control unit 5. Each firing circuit is supplied from a separate secondary winding 4 to provide D.C. isolation. |
