i want to make an inverter ckt of i/p vg 12v dc and o/p vg 240v ac , i need 2 - 3A current at o/p side.
and i wants to do it without center tap transformer and i can use 12v to 240v stepup transformer.
thank u for reply,
I dont use any microcontroller, using a 555 ic convert 12v dc to 12vdc 50hz square wave and fetch it to 4013(d - f/f) ic to get 2 toggle signal of 12v 50Hz and then fetch these 2 signal to MJ11032 to amplify current which is connected to center tap transformer (12 to 240v step up) but am unable to get 25A(getting 12A)current at primary side pls help me..i need at least 2A at secondary.

This won't be a very good circuit, especially for 500W.
Use a PWM controller such as SG3524 or SG3525.
For driving the transformer, use MOSFETs to minimize losses and maximize efficiency.
Use feedback to maintain/regulate output voltage.
Also manufacturer datasheet tell on what temperature, usually they give data for 25C. Its hard to keep 25C of parts, where even ambient temp is over that. ;-) Marketing is amazing.
But best learning is if you try to make, theory is nothing without practical exams. When device get hot you can fast turn off, measure and monitor, and make conclusions.
