Can any body present here may help me in understanding and making a UPS based on SMPS AC to DC converter so that there will be no need of any type of transformer and the UPS would not be bulky and heavy. It should handle be capable of handling atleast 500Watts of Power.
Thanks in advance

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

Hi good day.
I am using some 6Volt batteries that you can pickup at walmart, to get either 12V dc or 18V dc. I was wondering if there is a way to achieve the same outcome using an AC/DC converter. When I search the net looking for a converter there are just too many to understand what will work similar to 2 or 3 6Volt batteries in series. Any idea

1. For AC-DC conversion, the ripple is difficult to compress. But in DC-DC conversion, that is easier.
2. Telecomm equipment always use -48V DC, that is safe to human body. But AC, say 110V or 220v, is dangerous to operator.

As already dito, the perfect way is to change the primary of mains transformer from 110 to 220v, and I know this is not expensive.
I think any other CHEAP solution will carry noise, or something else not very good.

If you need very low power you can do by voltage multipliers , Other wise you can run a 12v DC motor coupled with a 300V DC generator to get the output. That is the only way
How do you mean only way? Can you elaborate and give us some light on this?

It depends on the application. If the 220v is AC mains, the current is low and you don't mind the health risk, you can do it with two resistors. Otherwise I would suggest a 220v to 5V transformer is the best solution.
