Yes it is posible!! but need some modification in op-amp!! and if you want an output wattage of 200watts you need 4pcs 2n3055!!

would it be possible to use 2n3055 's in parallel instead of using IRFP260?? the inverter that i have made so far puts out 150vAC and 10amps yay =D

What voltage you are using to the harry's inverter?
are you using this inverter? http://www.sm0vpo.com/power/invert1_00.htm

if you using that inverter to 12volt i think i wont deliver the full wattage you are design!!

i was built his DC-AC inverter 2 years ago but my inverter does not work for 12volt battery to the flourecent lamp and colored tv, but it work to bulb.

so i was modified his diagram to work with 12 volt battery

here is the modifed diagram:


as you can see i have change the 12volt regulator to 8volt regulator to make the multivibrator is stable if the voltage was down to 11volt! and you will notice i have change the + supply for LM358 Directly to +12volt

Note: do not use this diagram to 24 volt and above, you may damage the LM358 Op-Amp!

hello im building an inverter but im having some trouble and wonder if yous can help

this is the schematic that i have used but i can only seem to get 120v AC and and when i run the transformer in parallel the circuit does not work

http://www.brighthubengineering.com/diy-electronics-devices/63708-how-to-build-a-low-cost-high-efficiency-inverter/#imgn_1

any help would be appreciated
