If you have a 24V battery, from anyways. Such as a battery for large trucks. Let’s say, you want to take it to the TV. You cannot do it. Why? It is low voltage. You need to use the 24v to 220v inverter circuit 300W power, at 50HZ like AC line in your house.
In the circuit above. It has a basic principle like others inverter.
First, IC-555 is simple clock pulse generators, to make the frequency in Square waveform. The VR1 has controlled a frequency output at 50Hz or 60Hz.
Second, CD4027 is JK flip-flop To split the signal into 2 different states.
Third, CA3140 and CD4001 and others parts around them, are used to control the output volts with adjusting VR2.
Fourth, Q1, Q3, Q5, and more components drive the primary coil of a transformer in half.
Another one half are also Q2, Q4, Q6 drive the transformer too.
Which, both transistor power MJ15003 or 2N3773 driver transformer 18V CT 18V, 10A, minimum.
VR2 – 50K controls the output voltage at 220V. It gets some voltage from secondary to feedback to comparator IC-CA3130. To set the voltage as want.
I feel impressed with who designed this circuit. Many points require the 6V regulator. The circuit uses 7805 which it is 5V regulated IC. Then, there are two resistors set the output voltage at 6V. The 7805 is famous than 7806. So inexpensive and easily get it.
C6 = 0.1uf metalized-film capacitor, 5% tolerance.

I am sorry that cannot show you more detail. Because I have just only the circuit and PCB layout. Although, they have only this one. But, they still are useful. I believe electronics have similar ideas of all.
Cautions! I never build this circuit. So I cannot guarantee it works. You have to get it if it does not work. It is not a mistake, it is a learning style.
