As long as LtPC1238 is regarded as a power OP amplifier, the working principle of this circuit
is easy to understand. The voltage amplification factor is determined by the resistors j and R', A≈48
times (33.6dB)o between the output terminal and the ground, Ca is the impedance correction component ,
which increases the reactance and stabilizes the circuit operation.
The boost ratio of the output transformer is given by the formula. "=,/Z:/Zi calculation outlet In
the example, n=2, so when the load is 6000,
an amplitude above 40vl.r can be obtained.
