Is there any criteria to make the DC voltage choice in the presence of many supply voltage in the electronic cart?
For example: supply voltage: 12v ; 5V ; 3.3V ; 1.1V ; 1V
For the AC voltage : 220v
So what supply voltage should I choose for the first conversion?

Now, I have a 220v/12v transformer.
I wan to build with it a 0..30V power supply.
Do you have any idea?
Or I just build a 0..15 V power supply?

Go to this site:
There you will find info on 12v-120V inverter. The only thing you will need to change is the output power transformer which, in your case, should have HV winding for 220v ..

hi all.i want a circuit that convert 220v AC to 12v DC without using transformer.i want it give me not less than 40 or 50 mA.and also it costs so cheap.its better not using an ic.

That's unusual. A common inverter would convert 12v DC to 220v AC.
What output frequency? How many watts?
Do you want to buy one, or design one?

From what you ask it sound like you need a 220volt inverter This will give you a 220volt 50hz supply and these can be bought very cheaply now as it is the sort of thing people use to go camping and run tvs and radios etc fro a mains supply.

Could you try and explain what you mean. An inverter won't convert 12v to 220v. Try a step up transformer if it is ac.
Sorry, I'd never heard of this type of inverter!

You probably have a 50% duty cycle. This explains the doubling of the voltage. You shouldn't attempt to use a boost converter to step up 12v to 220v. Duty cycle will be tiny. Peak current will be huge. Better to use a push-pull converter with transformer or any other suitable transformer-based converter.
The inductor you used is too small. It burns

For isolation and safety, you should use a transformer-based power supply instead of building a non-isolated 220v to 12v converter, especially considering that the power requirement is 72W.
Maybe you don't want to use transformer because of the large size of the 50Hz transformer. In that case, you should be using SMPS circuits. But, even they wi

I don't agree either with the LED solution neither with the series solution. Things are quite simple:
Check the Wattage of the bulbs ( POWER disipation in each one of them). If it is say 10Watts each, then do as following:
SAY you have a 220v as main supply. Then Connecting all the bulbs in parallel will cost you : 30x10=300Watts. therefore
