Power amplifier with write

The common types of power amplifiers include Class A, Class B, Class AB, and Class D. The working characteristics of these amplifiers are: Class A works in the linear region with a conduction angle of 180 degrees, and has no distortion amplification for the signal to be amplified. The working conduction angle of the class amplifier is 90 degrees, and there is half-wave distortion. The working conduction angle of class AB is between 180 degrees and 90 degrees, taking into account the efficiency and distortion performance of the amplifier. The class D amplifier is working in the on-off state and usually requires a pair of tubes. In this way, the positive and negative half waves of the signal can pass, but it will also cause distortion. Its biggest advantage is high efficiency, because the class D amplifier only works when there is a signal, and the first three The required static power consumption is relatively high. for reference only!
