Transient Bank Holidays

In theory it’s a bank holiday here today, which means I don’t have to work. In practice, of course, there’s no way I could do this job if I didn’t work evenings, weekends and bank holidays, so today I’ve been moderating some exam questions and preparing some mini-lectures for the labs later this week. However, I’ve allowed myself some time off, just enough to get the new transmission line demo into some sort of working state.

It’s not very polished this one, and I’ve no doubt I’ll be returning to it later, but I thought I’d put it up here so I could, in some sense, call it “finished for now” and get on with something else. I won’t be needing it myself until next year.

It’s my first attempt at a transient circuit simulator. I’d never done one of these before, and after getting myself rather tied in knots trying to think of a good way to do this, and searching the Internet rather fruitlessly for some ideas, a student lent me a copy of “Electronic Circuit and System Simulation Methods” by Lawrence Pillage, Ronald Rohrer and Chandramouli Visweswariah. It seems to be a difficult book to get hold of for a sensible price, which is a shame, since it was very useful. To the authors: thanks, just reading the first chapter was enough to solve my problem.

Two chapters of the book now available… progress. Slow, admittedly, but at least it is progress.
