    build with CMOS 4047 that is the main component of this small voltage converter that transforms a 12V DC into 220V AC. 4047 is used as a astable mutivibrator, at pins 10 and 11 will have a symmetrical rectangular signal wich is amplified b 2 Darlington transistors and finally reach the secondary coil of mains transformer ( 2x10V / 60VA ).
