The 0nly disadvantage of this type of converter is the limited amount of current .

Increase the capacity of cap for less ripple voltage ..

What is the input AC volt and DC out put volt

The input is 220V you can use 110V but change the cap to double to give the same current

The output set by the zener diode . But in reality it effects by the load if the load take all the current and left the zener with no current

The input voltage is 155Vrms or 220Vpeak. @mohamed, what you mean is probably 311Vpeak

Because the program can not represent the rms value . I am dealing with peak voltage as rms . It is absolutely wrong but it is better than multiply and divide all the time by square of 2

Input voltage is 220v rms and 110v rms in reality.. but in program they are peak values

Its not a big thing to multiply by 1.414

And you have to take a decission were to place ground. Having it twice at different potential is bad and short circuits everything between both grounds.

In reality in my circuit I have to reference voltage one for the nutral of my Ac voltage . And one for the the negative portion of bridge rectifier .. so two grounds(reference) but not the same . And since the program considering it as one you are right i get to remove the nutral one ..
