Short circuit of a high voltage high current MOSFET MATRIX Switch
Résumé
In France, one joint program between Commissariat à l'Energie Atomique (C.E.A.) for the research part and COGEMA for the industrial application is the development of the Uranium Vapor Laser Isotopic Separation (SILVA). The Power Electronic Laboratory from the C.E.A. in Pierrelatte is in charge of development on power supplies for Copper Vapor Lasers. For this application, the strategy of the laboratory is the association of thousands of small standard components on printed circuit board as a cost-effective high performance and reliable solution. For PCIM, in 1999, [1] we presented a Keynote-paper about the strategy of the laboratory and we gave an overview of some different switches with MOSFETs, IGBTs, Thyristors, Diodes and nanosecond switches with standard MOSFETs. The three first switches are very fast turnon switches for capacitor lines or pulse forming network discharge applications. These three switches are not designed to switch off a high level of current. For high voltage very fast applications, turn-off switches are very difficult because of short circuit. The inductance is low, so it is necessary for the switch to limit the current and to open this short-circuit current. Now, we have a new fast 500 A MOSFETs MATRIX switch for high voltage modulator with a very good short-circuit behavior. We present this new switch :-500 A 10 kV module switch short circuit behavior high voltage fast modulator design some industrial applications.
