Critique my circuit description...

This is my description..."The transistors Q3 and Q4 come together to form a BJT push-pull amplifier for the purpose of amplifying the AC power output while also minimizing distortion ( distortion is minimized because the sine wave is amplified in both the negative and positive cycles thanks to the push pull action, which is necessary for optimum function of the transformer).When we apply a sinusoidal signal at the input of the amplifier, we get oppositely phased base currents. Due to the nonlinearity of the transistor the output current contains harmonics in the form of <Ic1 = I0 + I1 sin t + I2 sin 2t + I3 sin 3t +...> The collector current of the second transistor is 180 degrees out of phase and is represented by <Ic2 = I0 + I1 sin (t + ) + I2 sin 2(t + ) + I3 sin 3(t + ) + >…. Which is then simplified to <Ic2 = I0 – I1 sin t + I2 sin 2t – I3 sin 3t + …>. The total output current is the difference between Ic1 and Ic2 which is a nice invariant signal. This super strong nice current is then fed to the second transformer. Once at the transformer, the transformer manages to match the effective resistance of it’s output to its source resistance, which in turn maximizes our power output into the multiplier. The current leaving our second transformer is then provided with a return path by diodes D5 and D6 where it is fed back into our system for maximum efficiency."

Is this correct? How can I make it better? If something is wrong, what would the appropriate right answer be?

Explanation / Answer

The system consists of an AND gate acting as a switch connected to the primary of the transformer T1 at the initial stage. The secondary of the transformer is connected to a bridge circuit for the process of rectification.

At the next stage,power supply is given to operate transistors Q1 and Q2 and a zener diode is connected to operate at reverse bias condition. Transistors Q3 and Q4 are forming a BJT push pull amplifier in order to minimize distortion because if distortion is more,the voltage or current waveforms do not follow the prescribed path and hence the input voltage for the transformer is distorted which at the same time provides distorted output. The base of the transistors Q4 and Q5 are given base signal through the diodes connected in opposite direction to each other by tapping from the transformer primary. All these together connect to the primary side of the transformer and the secondary is connected to multiplier which accepts multiple inputs and multiple outputs. In the multiplier,the output power is increased and from there the current is given to transistors Q1 and Q2 for increasing the efficiency of the system.
