Sine wave power inverter

[tAhm1D]

Hi mincing,
What is your progress regarding inverter? Do you go through the postings here or you left out? I can help you regarding sinewave inverter. Hope to hear from you again. Thanks.

Dear Tahmid,
Thanks for the msg.

I have developed the sine wave inverter but open loop.I am controlling the amplitude based on the rectified DC from output sample.I gotstuck here as I could not find the right formula for closed loop control with sine as iput to ADC.

It would be great if you could throw some light on this,

If you have any guide lines or app notes pls.share.


Thanks again,
mincing

i think you need to provide the plant(inverter) specification most importantly the output filter to be able to develop a model for which ever compensation model to be addopted could be designed.you equally need to specify your power level.

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
