brother, i got one circuit, and i like it too due to its simplecity and it is also very easy to buit. but i dont have its values for 1000 watts. can any body help me to suggest about the specification of the Transistor, copasitor, resistors and Diod which would be using in the process of building 1000 watts Inverter. here is its ciruit and the readings.

Part Total Qty. Description Substitutions
C1, C2 2 68 uf, 25 V Tantalum Capacitor
R1, R2 2 10 Ohm, 5 Watt Resistor
R3, R4 2 180 Ohm, 1 Watt Resistor
D1, D2 2 HEP 154 Silicon Diode
Q1, Q2 2 2N3055 NPN Transistor (see "Notes")
T1 1 24V, Center Tapped Transformer (see "Notes")
MISC 1 Wire, Case, Receptical (For Output)

Aamir,
That inverter circuit doesn't work. Its capacitors are backwards, its 2N3055 transistors have a base current too low and they have avalanche breakdown.
The capacitors blow up because their polarity is backwards and the high current of the avalanching transistors is in them.
Its output power is about 25W just before it blows up and its output voltage is low.
More powerful transistors and transformer has nothing to do with how much power it makes.

Read about it in the long thread about it in the power supply forum at www.arroncake.net .

hmm brother actuly i used this circut with series of 1047 transistors. and with higher power transformer and i think it worked.

USE TATNTALUM TO AVOID HEAT AND EXPLOSIONS and it will make your projects life longer...

I found a very good 500W mosfet based Inverter

which is simple & relibel

24 Oct 2009 16:20 12V DC to 220V AC inverter circuit but 3 phase

How would one go about this problem. Producing a three phase circuit that runs on a 12v battery and could power a 1kw three phase 220 electric motor.

It's seems like quite a challenge. Single phase doesn't prove too much of a problem but three phase seems a real headache.

Any ideas or should i change subjects and just study c++ or something like that.

Thanks
