Introduction: DIY 60w, Portable INVERTER

Hi, this 60w home made portable inverter. Inverter are of 2 types mainly square wave and sinewave. The design discussed here is a 60w square wave inverter.

Step 1: Working Concept and CIRCUITRY

The design here is using an astable multivibrator (also known as free running oscillator) as oscillator for generating square wave pulses at a calculated frequency , The square wave pulses generated from low power 2n2222a transistor are fed to N-CHANNEL MOSFETS for amplification of power. Finally the generated AC POWER is fed to the 12v side of power transformer and stepped up to 220v or 110v ac (as per your country specification).

Step 2: Materials Needed

1.Transistor 2N2222A - 2pcs
2.1uf capacitor - 2pcs
3.12k Ohm resistor -2pcs
4.680ohms resistor 2pcs
5.N-CHANNEL MOSFET - 2PCS
6.12-0-12 TRANSFORMER 5AMP TO 10AMP.
7.BOX, GENERAL PURPOSE PCBs
8.12v 7.6ah battery
Misc. Switch, plugs, wires, etc.

Hi, thanks for watching, but I don't know why you are unable to download Pdf, may be your device doesn't have Pdf converter software, or you can contact instructable on that problem because Pdf download services are provided from the side of instructable servers, and not from the author's side.

good idea ... please respond >>> can be more power ???

ex 500 - 1000 watt

:-)

Yes for more power like 500w use 25Ampere, 12-0-12 transformer and a 12v,100ah battery. 680ohm resistance should be of 1w. For more stable output use an ic 555 astable multivibrator.

author

And transformer must be 600w, means 12-0-12 50amps

author

And also use 3pair of MOSFET for 500w, 3mosfets each side.
