Talk:MOS-controlled thyristor

The schematic is wrong. The lower MOSFET needs to be a P-Channel. 77.20.15.153 (talk) 04:43, 26 December 2014 (UTC)

Can someone please give an example of where to buy such a device? Also, what is it used in?

An Improved PSpice Model for the MOS Controlled Thyristor by Goce L. Arsov, Ljupco P. Panovski

Abstract - MOS controlled thyristors (MCT) are a new class of power semiconductor devices that combine thyristor current and voltage capabilities with MOS gated turn-on and turn-off. The PSpice model for the MOS controlled thyristor, capable to simulate the breakover and breakdown characteristics of an MCT and to work properly at high frequencies, is proposed in this paper. The model is quite simple and it presents the MCT characteristics during turn-on and turn-off. It is derived from the two transistor equivalent circuit of the MCT by expanding the SCR model presented in the references. The gate control section consisted of a PMOS and an NMOS is modelled using simple RC circuits for controlling the turn on and turn off times and with simple diodes (DPMOS and DNMOS) to isolate the operation of the MOSFET's in such manner that the triggering pulse of one polarity activates only one FET. The turn off capabilities of the PNPN structure in the MCT model are enabled using the voltage controlled switch SP. The switch is n ormally "ON" (VON is set to 0 V, and VOFF to -10 V) and is only used for turning the MCT off. This way, the breakover and breakdown voltages will be dependent only on the diode characteristics included in the model. In order to test the modified model characteristics extensive simulations have been performed (some essential results are presented in the paper). The complete PSpice input listing for the simulation results are given in the Appendix. The comparative simulations have been performed using the PSpice model for P-type MCT (MCTV75P60E1 - Harris Semiconductor Corporation) available on Internet. The model has passed all performed tests and can be used to analyze various types of MCT power converters. All simulations have been performed using the PSpice evaluation version 5.0a and its inherent method of integration. —The preceding unsigned comment was added by ArizonaWeird (talk • contribs). --- http://www.americanmicrosemi.com/information/spec/?ss_pn=MCTV75P60E1 — Preceding unsigned comment added by 178.190.11.141 (talk) 17:33, 6 July 2011 (UTC)

No! It wasn't invented by IEEE, it was invented by someone at General Electric. IEEE doesn't invent things, they coordinate standards and technical journals. Arghman (talk) 03:10, 18 July 2013 (UTC)
