audioguru Posted January 6, 2007 Report Share Posted January 6, 2007 Hi Lesr,It is good that you used efficient Mosfets instead of old transistors.Does the CD4047 directly drive the Mosfets or did you use the dual opamp in between?I just noticed that our "corrected" project uses two quad opamps instead of a single dual opamp.

lesr Posted January 7, 2007 Author Report Share Posted January 7, 2007 hi i use lm358 or 4011 for dvid the signal Quote Link to comment Share on other sites More sharing options...
MP Posted January 7, 2007 Report Share Posted January 7, 2007 Hi Lesr,Congratulations on your project!As you have found, there is a lot of latitude when making a square wave inverter. You can use various op-amps or most any digital gate to provide the signal to the transistors.Thanks for posting the pictures of your project.MP Quote Link to comment Share on other sites More sharing options...
lesr Posted January 8, 2007 Author Report Share Posted January 8, 2007 hi mp the emi filter is very important to remov noise from out put nobody worry about it and her is last picture for old inverters i made [img width=680 height=453][img width=680 height=453][img width=680 height=453] Quote Link to comment Share on other sites More sharing options...
