| LED2 light and LED3 off | Restart failure (if 5 times cannot restart successfully and prompt failure, it needs manual exclusion). |
The basic principle of a power amplifier
High output power
The output power is required to be as large as possible. In order to obtain a large power output, the voltage and current of the power amplifier tube are required to have a sufficiently large output amplitude, so the tube often works in a state close to the limit.
High efficiency
The efficiency should be high. Because the output power is large, the power consumed by the DC power supply is also large, and there is an efficiency problem. The so-called efficiency is the ratio of the useful signal power obtained by the load to the DC power supplied by the power supply. The larger the ratio, the higher the efficiency.
Non-linear distortion should be small
Non-linear distortion requires the power amplifier circuit to work under a large signal, so non-linear distortion will inevitably occur, and the greater the output power of the same power amplifier tube, the more serious the non-linear distortion, which makes the output power and non-linear distortion become One pair of main contradictions.
However, on different occasions, the requirements for nonlinear distortion are different. For example, in measurement systems and electro-acoustic equipment, this problem is important. In industrial control systems and other occasions, the output power is the main purpose. The requirement of linear distortion is reduced to a secondary problem.
