I need your help to build power supply to get these voltage levels ( 110VDC , 12VDC , 5VDC ) , I have a transformer (220VAC to 110VAC) and a bridge to get 110VDC but after that to get 12 VDC what I can do ?
power supply help ?

few choice...
1. use a wall-wart transformer
2. purchase another transformer
3. purchase a ATX power supply, everything is done and almost cheap.
4. build any kind of fancy voltage regulator.
Without knowing your current and safety requirement, it's hard to tell.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

is there any circuits to build by myself without usin atx power ?
|
Well, I don't know of any freebies like that myself, but Google could be your friend.
220 to 110AC would give you with a full rectified wave 110*1.4142~=156 volts.
You still haven't told us your current requirement...

oky I have A dc motor work at 110VDC , so I build driver circuits to give us variable voltage to motor , using PWM and PIC

Again, how much current do you need (ma, A)
