Abstract:
An emitter turn-off (ETO) thyristor comprising:a gate turn-on (GTO) thyristor having an anode, a cathode and a gate; a first switch, consisting of a number of paralleled metal oxide semiconductor field effect transistors (MOSFETs), having a drain, a source and a gate, the drain of the first switch being connected to the cathode of the GTO thyristor; and a second switch connected between the gate of the GTO thyristor and the source of the first switch, said second switch having a control electrode, the anode of the GTO thyristor and the source of the first switch serving as the annode and the cathode, respective, of the ETO thyristor, the ETO thyristor having four control electrodes, the gate of the GTO thyristor, the control electrode of the second switch, the gate of the first switch, and the cathode of the GTO thyristor.
