Guest Kasamiko Posted May 21, 2006 Report Share Posted May 21, 2006 Hey guys,Another power inverter design 12VDC to 220VAC @200Watts with automatic power ON feature!! Quote Link to comment Share on other sites More sharing options...
MNA Posted May 23, 2006 Report Share Posted May 23, 2006 Hi Rhonn,Have u build it? ...... Square wave?This post has not been viewed more than 34 times as it was on the first day(If I'm right).....I think u should have declared that the picture has been uploaded.....It seems to me that u r really interested in inverters :) :)MNA Quote Link to comment Share on other sites More sharing options...
audioguru Posted May 23, 2006 Report Share Posted May 23, 2006 The schematic is a 10M bitmap and is more than double the size of my screen.I reduced it to 40% size in MS Paint and saved it as a very clear 86k PNG file. Quote Link to comment Share on other sites More sharing options...
Guest Kasamiko Posted May 25, 2006 Report Share Posted May 25, 2006 I havent build it yet..im planning to revised the timing circuit..that is too complicated.. ;DI sucessfully uploaded it after nth times!!Yes you are right..im really fascinated with inverters.. ;) ;)Let start SKINNING this circuit..

oldgrandpainmi Posted May 27, 2006 Report Share Posted May 27, 2006 Boy oh boy, it been a while.Remind me, please.My father and I developed a smaller inverter years ago, based on 6 PLL's, to control motor speed in a telescope tracking system. The voltage I believe, was 110ac, but we changed the freq to adj speed. We had to smooth the square wave outputs also. I believe we used NPO caps. It appeared to be a lot closer to sine that square, but with a faster rise/fall time than AC. If the output is square, couldn't NPO's be used in this application, also?oldgrandpainmi Quote Link to comment Share on other sites More sharing options...
Guest Kasamiko Posted May 28, 2006 Report Share Posted May 28, 2006 I think NPO caps are mostly used on frequency sensitive circuit (tuning circuit in RF) to minimized frequency drift..I can't see any advantage using it here..since the clock is precisely crystal controlled in this circuit..

HIRHOSHY Posted June 16, 2006 Report Share Posted June 16, 2006 dear friends , This elevator of voltage, does it(he,she) work perfectly? Or has it(he,she) algun problem for his(her,your) manufacture? Thank you Quote Link to comment Share on other sites More sharing options...
