Can anyone help me with a simple circuit to provide me with this, its a basic project but i need one to give me atleast 250-300watts. or about 2-3 amps output, want to use a 12volt battery bank or a 12volt dc power supply to use as the supply for it.
Note 12vdc-120volt ac @ 60Hz.
parts number would be greatly appreciated or any info on this, i tried searching for circuits for it but kept getting 12volt to 220 volt at high output wattages( can i substitute the transformer from the 12volt to 110-120 ?) i am basically new to this novice at most.

Try 2N6284. Or, try any from this list : **broken link removed**
 

This circuit is very nice and small. But can I create oscillation using single transistor?
I can take inductors and capacitors of any value. I only want to generate oscillations.
 


The circuit can be use for the RF function and requires much knowledge to design it. But I want the basic knowledge to design a simple oscillator(specially using one transistor).
You know that, after knowing particular values of inductors and capacitors and by properly arranging them with the feedback mechanism, we can generate oscillations with one transistor. I think that clarifies the basics of oscillators and of course the circuit can effectively reduced in size.
Can you please give me any formula or required values or any knowledge for design a simple one transistor oscillator.
 

New Bitmap Image.JPGYes first install ltspice its great for cheaking out circuits and changing values seeing the actual output on scope like screen.
rc shift oscillator . or wien bridge google it out

What kind of features do you need? The more features you need, the more complex the circuit becomes. Do you need just the inverter or other protection features as well, such as low battery protection, output feedback,overload protection, etc.

For 250-300W, you should be looking to use MOSFETs instead of BJTs. You'll get a lot more efficiency, and so you'll get much better battery backup.

Hope this helps.

Click to expand...

Basically i was looking for the overload protection in the inverter and one that will give me a 60z sine wave most of the circuits i got doesnt help much, i dont need much power output from it though its for a small project to effectively run power a 100-200w load, can you help with a circuit that i can simulate on multisim on an inverter using the mosfet design? please....ty!
 

Thanks to all. RC-Oscillator is the best in one transistor oscillator. Also Pravesh, you can use the RC oscillator to reduce size of your inverter. Is it?
