Inverter 100W with IC 4047

This is a schematic inverter 100W, to produce 100W of power we use 12V10A car battery. R1 is a potentiometer that is used to set the output frequency to be at 50-60 Hz, which the inverter will be used for our home electronics. If only to try, you can use the step-down transformer CT in reverse, the input at 9V-0-9V and the output at 220V. Transformer 10A that we must use in order to produce 100W of power. This Circuit is built with a 4047 to generate pulse, two of 2N3055 and a transformer  to increase power. You can replace the transistor with other transistor if have a same spec.

list of components:
IC 1        4047
R1          250K Potensiometer
C1          0.022uF/25V
R2,R3    10 ohm, 5 watt resistor
C2,C3    68 uF/25V Tantalum Capacitor
Q1,Q2    2N3055 NPN Transistor
TR1        see text

This inverter can be designed to produce greater power in a way by substituting transistors and transformers (power stage) are more powerful components.
Note: use a heat sink to each transistor for a good performance
