I made a few simple inverters and also simple amplifiers and I have noticed that audio amplifiers produce pure sinewave. OK now I realize that audio amplifiers clip when they are over driven (passing the supply voltage or current). If I am to use an audio amplifier as an inverter the best way I think to get high power would be to use several batteries in series to achieve a higher voltage.
But what if I want to use 1 12v battery but be able to pull high current from it?
The trick is normally the amplifier require a dual polarity input so I think 2 batteries would be needed to be connected in series and the point where the batteries are series would be the 0v rail.
Couldnt I build a circuit to convert a single supply into a dual polarity supply with high current output.
So the input of the amplifier could be supplied with a simple pure sinewave oscillator circuit ( I was thinking off a 555 circuit) im not a pro at any form of designs either amplifiers or inverters but I do tend to read about them often and what I tend to realize is that pure sinewave is easy to produce but it seems to be complex to amplify given my limited knowledge thats why I wanted to try this method of creating a simple circuit to send puresinewave signal to the input of an audio amplifier while using 1 12v battery and also still gain high power, I figire there will e efficiency issues but can anybody elaborate on this method.
