Hi,i am new to pspice and multisim.can anyone help me to design the DOUBLE STABILIZED (±12V) POWER SUPPLY in pspice or multisim without using LM7812 or LM 7912 .If not can anybody supply me the schematic .can mail me at zakir_mohd2000@rediffmail.com
i have the specifications as
1. Power = 12V ± 0.1 V
2. Input : 120V, 60Hz
3. 2 Outputs with common ground :
4. Maximum current : 100mA
5. Noise and Ripple < 0.1% in 0-100KHz frequency range

You do not "design" in Pspice or multisim. You design it first with pencil & paper & calculations. You can then simulate it with your choice of software if you wish.
Nobody is going to do this work for you! If you want help, you should design it yourself and post any questions and/or problems you have. Quit trying to get a free lunch.
Right, you missed the title... :lol:
I was wondering when zaku will notice.....
Zaku, it'll be better to add resistors of equal value, say 10K ohms in parallel with C1C2 and C3C4. Probably at the o/p of the Opamps too. They should equalise the potentials to zero at he center.
That schematic that is posted is a poor design. The original poster keeps editing his first message which make the thread more confusing to anyon e reading it. You can't drive 100's of uF with opamps. It wont work. I suggest the original poster learn more about opamps & regulators before wasting time hacking things up in Multisim. This is very discouraging to see how this thing is progressing. I can't watch anymore LOL!
