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 sinusoid. The dissipation of the output transistors is cooler. incandescent lamp, mini motor etc. by the given converter circuit. operated.
