inverter scheme

This is a dc to ac inverter scheme which has a capacity of 100W maximum power from a voltage source voltage 12VDC to 220VAC. This circuit according to the designer may last up to 4 years and as can be seen below, the circuit is quite simple. When not know what the inverter also read articles about the inverter technology.
The heart of the circuit is IC 4047 CD that serves as an unstable multivibrator, pin 1 and pin 2 on the IC is the foot that determines the frequency of the resulting circuit. As for the series itself is set on 50Hz.
Inverter IC 2 x CD 4047 produces output which is then amplified by the amplifier transistor TIP122 early on both sides which is then amplified by the 2N3055 used in OCL amplifier on both sides with each side of the second transistor amplifier end.

Schemes DC to AC Inverters DC to AC Inverter Scheme 220V 40Watt
Transformer used is the scheme of the DC to AC inverter is a type of CT (center tap) 9V with a capacity of 10A, but if no one can use transformer 5A, although later on the power generated is only 60Watt maximum.
In designing the dc to ac inverter circuit 100 watts are some things that must be considered, namely:

    
Batteries for the experiment can use the car battery as a source of 12VDC
    
For setting the frequency can be set via the POT R1, setting it to 50Hz using the AVO which supports / Oscilloscope
    
Be sure to use the fuse / fuse 10A guard duty in case of short
    
Use socket for inverter IC 4047
    
Use simple equipment, the resulting output is not suitable when used for computers or other sensitive equipment.
    
Use a heatsink for 2N3055 Transistor
The factor that determines the power capacity in the scheme of this inverter is the maximum current at the end of the transistor amplifier and a transformer is used. For example to get the most out 100 watts using a 12VDC battery voltage then the battery capacity should be ~ 8A. Or:100 watts / 12VDC = 8.3 A in accordance with the power formula P = VXI
