Audio power amplifier circuit pattern example analysis of the triode power amplifier, and the difference between small signal amplification is that the output current is relatively large, that is, the output power is relatively large. A typical example is the sound.

According to the triode working area, the power amplifier is divided into ABCDE and other categories. The following is mainly to understand the class A power amplifier.











Let’s take a quick look at Class B and Class AB power amplifiers.



Finally, let's look at the circuit of a loudspeaker.

This is a megaphone circuit that can be used practically. Let's do it!
