I need the schematic for 15Vdc to 12vdc converter
circuit. The converter
must have high power rating (more than 100W) so that it can drive various loads from my dc-ac inverter. Please help! >_

Can someone suggest to me a multiple input AC to DC converter module or chipset that converts 220vac to 5Vdc.
The scenario is this, in a control panel, there are lamp indicators that lights up upon completion of each process (flood control process) i need to detect each lamp indicator as it activates so that I could remotely control each device

100mA is a lot of current for a power supply that is converting from 220vac, if you are not using any transformer.
It is also not safe (not for you, because you know what level of safety you have built it to, but concerned for the
other users who may not be aware of the lack of safety) unless you are very careful.

Hi to all.
I'm trying to build a forward convertor (220vac to 12vdc 25A) , but am having a problem with stability.
It's a single switch forward converter with a reset winding in the XFMR. I'm using 800V mosfet for switching.
The converter is using the old uc3842 controller chip. It is working fine (Nice and stable) at (...)

@ above commenters, some 12V amps (a lot these days actually) pump up the 12V to +/- 50v so that they can do the power advertised.
@ThorDruid, to get 12vdc 200A reliably from 220vac requires pretty decent switchmode converters, say 4 x 50A units with the o/p's paralleled, Ebay is your best bet for low $ here.
