Title: Static converter

Filed: 1973-09-20
Abstract: 1440475 Controlling frequency changes SIEMENS AG 20 Sept 1973 [22 Sept 1972] 44294/73 Heading H2F In a frequency changer of the type comprising a controlled-current rectifier 2 feeding intermediate D.C. to an inverter 5, a commutating circuit 3 comprises a commutating capacitor 21 in series with a first switching device 18 and a second switching device 19 with inductor 20 arranged to reverse the charge on capacitor 21, the first switching device 18 being turned on when the voltage across the capacitor 21 is appropriate so as to turn off the operative thyristors of the inverter 5. As described, the system supplies power to a synchronous, asynchronous or rectifier motor 1 having a Hall or permanent magnet device 6 responsive to rotor position and a tacho generator 7 responsive to speed. The speed-responsive signal is compared at 10 with a desired speed signal at 11 and fed to a speed controller 12 which provides a current-controlling signal which is compared with the input current at 14 and thus controls the conduction angle at 15 of the thyristors in the rectifier 2. Commutating capacitor 21 is initially charged positively by three-phase rectifiers 22. A pulse from the inverter firing system 8 is differentiated at 25 and turns on thyristor 19 so that inductor 20 tends to reverse the polarity of charge on capacitor 21. When the polarity reverses, diode 18 becomes conductive passing a reverse current through the operative thyristors of inverter 5 and the windings of the motor 1. This action turns off the operative thyristors together with thyristor 19. Capacitor 21 now recharges positively by the current Id. A Zener diode 26 feeds a signal to the firing system 8 to turn on the next pair of thyristors at the appropriate time. Photo-electric coupling is provided between stages 26 and 8.
