Define 'there is some problem about this circuit'
You mean apart from it's tiotally rubbish?.
Like many of the projects from that site, it doesn't work.
Ooooerr you are so harsh....
now i have circuit like this..
**broken link removed**
buat i can't find the component CD4047 in PsPice.
what component can we used except CD4047?...
Velleman once did a mains invertor that was xtal clocked....iirc it used a 4060 osc/divider to obtain a 50hz timing waveform and there was a feedback loop to maintain output voltage stability...Doesnt look like they do it anymore.....
But you can buy ready made mains inverters, better than the Velleman one, for very little money these days.
Your English is horrible but it sounds like you have a square-wave inverter that uses a PIC as its oscillator.i am new in this frem .pl help any body ...... i have req. pic 16f676 or 16f72 based sqer, wave inerter . not sine wave

Is something wrong with it?
The transistors have losses so a 5V-0-5V transformer should be used with a 6V battery.On the last circuit, could I simply change input voltage to 6volt ? and connect the output to 6v - 0 - 6v of transformator, does this action just make output power down to 50watt?
