Sine wave power inverter

[psdayama]

Hello!
just scroll down and U will find the schematic in jpg format.
I don't know if Saugata will give the code.
Some part he has already explained.

Hi there,

I did finish the project and managed low harmonic content and descent crest factor but need to improve on the distortion issues on mixed inductive loads.Please note that it is a commercial project and I just cannot share it on this forum. However I would certainly like to answer specific queries.

Off the track I would like to express my gratitude to PSDayama whome I met personally on my trip for the Microchip Master's Conference. A warm welcome and great hospitality moved me. I thank this forum too.

Regards

Sougata

Hi Everybody,
I met this nice chap SAUGATA thru this forum and very happy to
interact on subject which Im trying to learn from scratch.Of course
I am little old (>55years) but one is student all his life!
I want to thank the forum for getting to know many young people
and their expertise and exploits ;-)
Lets hope everybody gets on ahead with the subject matter.
Regards,
psdayama

Hi,
Atleast somebody give me a schematic of the inverter with uC. I would like to know about the snubber circuit and the ouput filter circuit. Could somebody help me out.

Hi I browsed through the forum.
Which JPG were you talking about!

Hi Mincing,

I would like to know which Avago(Agillent ?? ) drivers you are using and which MOSFETs. What is the intended configuration and if it is being directly connected to load or by a transformer.

Please give the required spec of your design in details.

i am using ACNW3130.seems to be of right choise.Welcome any comments.

I am using a full bridge configuration.with isolation transformer at the out put.Bridge would feed transformer.

Hi,

Please post at least a block diagram if you are not through with your schematic. Also it would be helpful to know exactly what are the specifications of your system or what you are trying to achieve. Otherwise it is hard to suggest a scheme.

Hi All,

Colud you please suggest me about Sinewave Inverter schematic.

Hi All,

I am going to desgin a 400VA-600VA Invertor using PIC16F676 microcontroller & IRF317, Colud you please suggest me your comments over it.

Other than the sheer joy of being able to say" I did it", Why?

money wise you will be upside down to roll your own.

I've got this unit (from Walmart a few years ago), physically it's the same thing, same case, same cutouts, same switch/led/positioning, same outlets, same everything, except mine has a fancy label on it and a cigarette lighter adapter instead of alligator clamps.

It's got a modified sine wave alright... I hooked it up to the 'scope awhile back. Yep, it's a MSW... 1/4 @ +V, 1/4 @ 0V, 1/4 @ -V, 1/4 @ 0V.... 90 degrees spent in each 'phase'. And the peak V was around 150V if I remember right, instead of the +/- 170V I would've thought it should've been.

P.S. What's an IRF317 anyways?
