Sine wave power inverter

[iw2fvo]

HI,
I am asking if there is a sample PICBASIC program and schematics to take as a reference for me to experiment a switch mode power supply using pic PWM.
Could you please give me some help on the matter ?
I do not need more than two amps of current and it will be a buck converter .
The PIC I will like to use is the 18f252.
I hope to read from you.
Thanks in advance

i have being into for a while but is square wave but want tsw

Hi,

I didn't get you quite.....

[adedeji]

im reallyin the act of making an inverter for a while but is square-wave using pwm ic but i want to start pure sine wave inverter,if i an get help from the forum how to proceed with it but not with double conversion cos i live in this part of the world where we import nearly everything and cost of importing is high so iwill use the bulky xfomers that is available or if u cant give me hint on how to mke a ferrite xfomers on my own thanks

Hi,

While we have been discussing sine wave inverter in this thread about the internals but not much as code example. Which PIC would you be using ? I wish I could provide some.

Hi,
I want to build up a sine wave inverter too using the PIC18F452. Any help ?
Is there a schematic diagram and some code to take as a referene ?
Thanks

Please some one help me out am having some bad days burning my fets trying to put up this sine wave inverter posted on this forum, can some one please give me a solution why my FETs keep burning when I power it on to Mains input supply.
