Hi Guys Actually, you can use a 50/60 Hz xfmr up there at 500Hz just fine with no extra core dissipation. The flux density is reduced due to the mag current being proportionately less. the losses are

OK, Here I am as user D4394548 with a completely different identity and emal address. Still goes to http://tech.groups.yahoo.com/group/LTspice/ as it did before. So I'm SOL on search:) Now I have to

Hello Patho, It doesn't seem to have occurred to you to check if LTspice already included a model for BC547. If you had checked, you would have found it in the standard.bjt file in the LTspice

Yes, I was thinking that might be a solution. But isn't neo giving problems posting? So I'd need two separate logons, one for search and one for posting. But if they have different urls, then the

No problem here including searching, I use the link at the bottom of each email.

Hello, is there anywhere a LTSpice model for a 1,25V LMV431 voltage reference? Thank you Mario

Thanks Helmutsennewald But I knew that in Ltspice models are .spi, .cir and .net formet. I have face problem that there dodes not create symbol automatically in .mod format. Please help

I posted an example file under temp, the file is "Switch_test.asc"

I thank you Andy, but i've made a small circuit with one switch ON and another OFF and they work exactly the same, so i don't understand the difference. Enrico

Hello, LTspice accepts any file name for models. Even a filename like partho.duet would be OK. Best regards, Helmut

Thanks John. I Find out BC547 but there have no spice model of bc547 in Fairchild Semiconductor. I downloaded BC548 spice model but this file is .mod format. can I use it? If not how can I find out

Business Kid, Yes: You are very OT as you don’t answer to questions. Sorry if you had never could understand W 98. Don’t you know that W 7 is just like Vista SR2? I don’t agree with you at all.

Then you have got the voltage wrong. 36V ac translates as 50.9V amplitude. Does it? Modify the simulate statement for .tran 0 100 99.98 You will see that all the problems you see in the first seconds,
