6v 12vdc converter circuit
For example, you could run 12V car accessories in a 6V (British?) car.he circuit is simple, about 75% efficient and quite useful.
By changing just a few components, you can also modify it for different voltages.

Cmos 4047 Power inverter 12Vdc to 220Vac circuit and explanation
This converter has a central component, the CMOS 4047, and converts a 12V DC voltage to 220V AC voltage. 4047 is utilised as a astable multivibrator. At pin 10 and 11 we find a rectangular symmetrically signal which is amplified by tow Darlington transistors T1 and T2 and finally reaches the secondary coil of a transformer network (2 x 10V/60VA). Primary coil terminals voltage is 220 alternative voltage. To obtain a better performance use a toroidal core transformer with reduced losses. With P1 the output frequency can be regulated between certain limits (50…400Hz).
