the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > this topic gives a b(OCL) complementary symmetry power amplifier circuit of input and output parameters, required to solve the maximum distortion power output Po.

Generally speaking, the maximum undistorted output power of OCL circuit is calculated by the following formula:

Po =(Vcc / 2) ^ 2 /(2 * RL)

Where Vcc is the DC supply voltage and RL is the load resistance. But this formula is for the ideal case, there is some distortion in the actual circuit, so it needs to be corrected according to the actual situation.

Specifically in this problem, we know that the amplitude of the input voltage is 10V, and the amplitude of the circuit supply voltage is 15V. We can calculate the maximum undistorted output power according to these parameters.

First, we can calculate the output voltage amplitude of the OCL circuit:

Vo = Vcc / 2 = 15/2 = 7.5V

Then, we can calculate the maximum peak of the output voltage:

Vp = Vo * sqrt(2) = 7.5 * sqrt(2) ≈ 10.61V

Next, we can calculate the peak power output of the circuit:

Pp =(Vp/SQRT(2)) ^ 2 / RL =(10.61 / SQRT(2)) ^ 2/108 material 4.56 W

Finally, according to the definition of maximum undistorted output power, we can get:

Po ≤ Pp

Therefore, the value of the maximum undistorted output power Po is 5W(that is, Pp rounded down).

It should be noted that this calculation method is only an approximate calculation method, and other factors may affect the calculation of the maximum undistorted output power in the actual circuit.
