In a DC AC converter circuit, 555 integers generate square waves. Square wave transistors from the third end of the integrator continuously transmit and cut. Transistors are switched on from the 12 V winding of the transformer, which is the transmission section.
The variable currents passing through the primary winding of the transformer form a variable magnetic field.
The variable magnetic field generated in the primer creates high AC voltage in the thin-sectioned multi-winding secondary winding. Note: The circuit is experimental and has low power.
