Original poster: "Kurt Schraner" <k.schraner@xxxxxxxxxxx> Hi Steve,thank you. There is perhaps not much need to model detailed parameters of the IGBT itself, while the on- and off switching transients and the switching loss I^2*t shure are of some interest. But most of the time, a controlled switch of the kind you name, is probably enough. Currently I'm doing simulations for different induction coil "breaks", continuing the development similar to the "Andiruptor", but now oriented toward a capacitor discharge system.

Original poster: "Steve Ward" <steve.ward@xxxxxxxxx> Kurt, I typically just model them as "voltage controlled switches" with a diode across them as needed. What parameters of the IGBT did you really need to model?

I'm currently using Microsim 8 (student version), and if I have to speculate about the power circuit of an idea, I'm mostly building up the simulation, based on timed switches. Anybody can help me to find a better, less cumbersome and more realistic way to do that? Are you introducing published Spice models of IGBT's in local PSPICE libraries? Using other programs? Buying the unlimited ORCAD... etc.? Thanks for giving me some practical tipps, how to deal with the problem. Cheers, Kurt
