Sine wave power inverter

[iw2fvo]

HI,
I am reading for the first time this argument.
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 .
I hope to read from you.
Thanks in advance

Hi,

It would be better if you start a different thread cause a PIC based buck converter is different than a sine wave inverter.

provide the following though

What is the input voltage range (Min - - Max)
What is the output voltage required
Intended Frequency of the switcher (PWM)

MCU being used

BTW it is 2:15 AM in local time and I should get some sleep now.

Thanks,
vin=10 to 22 vdc
Vout=7 Vdc max
I out =3 A max

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.

The PIC I will like to use is the 18f252.
