First of all, you're not going to get a sinewave out if a 555. Secondly, this sounds like an extremely inefficient inverter. Third, you don't need 2 batteries to get a bipolar output, just a transformer.
These all are linear inverters, efficiency will be less than switch mode inverter. Why cant you try with standard driver module

A bridged class D won't need dual rail supply.since its class D I guess I would have to purchase an amplifier or probably try building the one I was discussing with you but how will I use a single rail when it requires a dual rail supply?
I live in a 60Hz country.
One time where I had to test a design across the 48 to 62 Hz range, I used a spare audio power amplifier and a sinewave oscillator. The output voltage was not enough, thus I used a common steel core transformer wired backwards: the secondary to the amplifier, and the primary as the voltage output for the device under test.
As others have mentioned, it was very inefficient. But I required only about 25 watts for short periods of time.
It is easy to convert an opamp or audio amp circuit from a dual polarity supply to a single positive supply. Simply add input and output capacitors and bias the input at half the supply voltage.
Mosfets waste a lot of power making heat in your circuit because of their high gate-source voltage.
Texas Instruments make some excellent class-D audio amplifier ICs with a fairly high output power.

He must have used a linear audio amplifier that wastes about 50% of its power supply power producing heat, instead of a class-D switching amplifier that heats with only 10% of its power supply power.Why would you say its inefficient, couldnt it be that you were using a inefficient inverter with an incorrectly rated transformer?
Please read my post. I never mentioned it was a class D amp.
All that I was saying was that audio amps may be used as a spare inverter in certain specific cases.

Enzy, you showed a high power audio amplifier that used a +60V and -60V (120V total) supply so I converted it to a +120V supply. The transformer simply stepped up the output voltage from its maximum of 100V p-p to the 340V p-p of a 120V AC sinewave.
A switching Mosfet has its load at its drain pin (not at its source pin) so that it can fully turn on when its gate voltage is 10V.
