hi
i want to create very simple inverter:one-phase full bridge inverter (for a lamp load)
i make waveform of control section
in power section i don`t have enough information
i want to know what type of elements i have to use?(for example if i use mosfet for switching,which characteristic is most important?for isolation of power and control section what element i have to use? and...)and example of each elements to use
regard

First of all you have to tell us the type of lamp that you are going to use:
-Incandescent
-Halogen
-Fluorescent
-LEDs
-Other type

How many watts? I think you can use a power transformer backwards.... 12v in the secondary, 120v out the primary. If you have a 20 watt 60hz transformer, I think you can pump more watts through it at a higher frequency, but I dont know what the frequency response of a power transformer is... I bet you can get 5khz out of it....

But you can buy a 12v 100w inverter in any flea market anywhere in the world. What innovation are you adding to this invention? It aint efficiency, otherwise you wouldnt use an incandescent bulb.

Ok,

Could you please be more specific for what you need.
You are trying to make a circuit to lit an 100W incandescent lamp. What is the nominal voltage of the lamp?

it`s only an experiment for me to create this circuit and i know that i can buy it !!
nominal voltage is 220V i think.

indicate that your experiment has come to the logical conclusion, that you are not able to create or make this circuit.
Your experiment is over! QED (quod erat demonstrandum)

You had better KNOW, or you could kill yourself or someone else.

Also consider that if this is a simple lamp load, there is no real need for a full bridge implementation. DC works just as well on an incandescent lamp as AC does. But the voltage you feed it will need to be different, or you will burn not the filament.

Writing code is like having sex.... make one little mistake, and you're supporting it for life.

There are schematics on epanorama... search for dc to dc converters and dc to ac inverters

i want to make this simple inverter(full bridge),because then ,i have to creat 3phase inverter(control:SPWM) for induction motor
and it`s first step for me
if anyone can help me for power section of this inverter(load is incandescent lamp:220v--100watts),please answer me
(i don`t want any other circuit...like converter or chopper!)
thanks

I have to create

Is someone making you create this or is it something you wan't to do? Your specifications seem to be evolving as time goes on which makes it really difficult to help. IE.

What about frequency?
Whether someone else want's you to make this or you wish to do it for the heck of it, the task is complex enough so that you should come up with a specification of what you really are trying to achieve.
As well as coding skills you will need some good linear electronic skills and the ability to do ferro-magnetics design.

As someone has mentioned the voltages are lethal.
Is this a school project or a paid job. If the former , which school and if the latter are you going to cut us all in? :D
