Abstract

1388992 Inverting V G YATSUK 21 March 1973 13554/73 Heading H2F An inverter comprises a polyphase bridge of controlled rectifiers 1 ... 6 and a commutating capacitor 17 chargeable with alternate polarity via a single phase bridge of controlled rectifiers 13 ... 16 and connectible to the controlled rectifiers 1 ... 6 by means of a commutating bridge of controlled rectifiers 7 ... 12. The commutating capacitor 17 is charged from a supply Un. Reactive power is fed to a threephase supply by means of a further inverter comprising thyristors 34 ... 39 via transformer 40. In Fig. 1 (not shown) diode 19 is reversed and connected in series with inductor 18. In Fig. 7 (not shown) the D.C. sides of bridge 7 ... 12 are connected to the supply U1 via auxiliary thyristors and inverse diodes. Details of commutating one, a group of or all thyristors are described with the aid of waveforms (Figs. 4 and 6, not shown).
