pls i need higher or updated version of multisim 10 or any other electronic workbench that can be use for simulation. the version i av does not contain SG3524(an oscillator) which i actually need for my project.(design of UPS). i will appreciate any help.

hello,
You can download a new version of multisim from national instrument website.
I advise you not to waste your time designing UPS or inverter with that IC.
Reason? You will find it difficult to get the correct PWM you need from it.
I have built about ten of it without clean signal.
You know bad signal can blow your MOSFETS

You can use a PIC to get a good PWM for your designs. Like PIC16F877. If you know how to program PICs.

Thanks

@ DIGITAL MAN, i really appreciate ur concern for me, GOD bless u with more wisdom. i would prefer PICs but i dont actually know how to program them, though i'll make inquiry and learn it. i will still appreciate u more if u can give me more clue on the PIC stuff, i actually want to design 2KVA UPS.if u av any circuit diagram of UPS, I will like to see too. pls furnish me with ur fone number and mail address, mine is 08034455663, oyewoledc@yahoo.co.uk.thanks so much.

HELLO THANKS TOO. am deep into PICs , u can contact me through digitalman117@yahoo.com.

There are so many talents out there who would rather have changed the world but was cursed to have come from africa nay nigeria.
trying to program pic requires dedication to learning the programming language. there are good ones out there like. , just contact me if u want to get everything u need to beging programming pics. I would have written it here but I had written on another POST which was removed by owners of this website. I don`t know why they did that.
