12 V DC / 220 V AC CONVERTER SCHEMATIC CIRCUIT DIAGRAM

 

The multivibrator (flip-flop) part of the oscillator produces a square wave of frequency 40-60 Hz. Square waves from points A and B of the multivibrator circuit trigger the drive transistors. Drive transistors supply power transistors. Power transistors drive a constantly varying current in the direction of the tuning primary windings (N1 and N2). Currents flowing through N1 and N2 generate an AC-specific voltage in the second.

In the circuit, the output transistors and the power of the transformer can be changed according to the desired power. Three capacitors with nF connected parallel to each other on the output help the obtained AC to resemble a sinusoid. The dissipation of the output transistors is cool12 V DC by 220 V AC CONVERTER SCHEMATIC CIRCUIT DIAGRAMer. incandescent lamp, mini motor, etc. by the given converter circuit. operated.

Circuits, schematics, and explanations are borrowed. Also on almost all pages, there are explanations about the shape of the working circuit of the circuit operation of the circuit.

A MULTIVIBRATOR is an electronic circuit that generates square, rectangular, pulse waveforms, also called nonlinear oscillators or function generators. A multivibrator is basically two amplifier circuits arranged with regenerative feedback.
The basic principle of the Astable multivibrator is a slight variation in the electrical properties or characteristics of the transistor. This difference causes one transistor to turn ON fast than the other when power is applied for the first time, thereby triggering oscillations.
Astable Multivibrators find their applications in delay and timing circuits and in the transmission and reception of radio signals. Monostable multivibrators are majorly used in analog systems in order to control the frequency of the signal at the output. 
There are three types of multivibrator circuits depending on the circuit operation: (i) Astable, (ii) Bistable, and (iii) Monostable. An astable multivibrator is internally triggered, whereas the other two types are externally triggered.
