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?

Hello I would like to design a power supply for a wireless transmiter (4W max output power with Vin=12v). I don´t know much about power supplies and I would like to design a reliable and more or less small one. I would appreciate any sch. or link.
thanks a lot anyway,

froggy so You want convert twice from 12v to 24V and next 24V to 220v hmm I don't think it's a good idea..
12v DC need to change 12v AC, next to 24V AC by 1:2 transformer (very large) next use bridge, caps to get DC and convert to 220v...
no this is very wrong idea....
here is an example simple (...)

Yes, you can charge with the same transformer, but not 8v. What you need is a primary voltage control, either variable or fixed. This is usually done using a triac or 2 SCRs and another tapping in the transformer (I used 140v). The control of the triac/SCRs is done using phase angle control with either opamps (a complicated circuit) or if you can u

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
