Ray, what free site are you talking about? We can't read your mind. How about posting a link to the schematic?RayJ said:While you are on the subject. I copied the inverter schmatic from the free site. The 2 PNP transistors listed don't exist. does anyone know what Radio Shack 276-2025 cross over to? and what watts do the resistors need to be?
Yeah, I just fixed that fairly simple inverter project that was full of shorts and wrong values on its original schematic, and added enough cheap 2N3055 transistors to keep the few original ones from melting.Oznog said:Even that is not a great inverter design.
Yeah, the cheap Chinese inverters are tiny, lightweight, have a built-in fan and a display of battery voltage, power output and other stuff. :lol:If you can, just buy an inverter. They're quite cheap and effective, much safer too.
Most cheap inverters have a square-wave output.akg said:except for purely resistive loads , is there any other use for the sq: wave inv: ?

Sorry, but you're talking rubbish!.
You could rewind an alternator to provide a higher voltage, as it is they are wound for low voltage and high current.
