Abstract

The invention discloses an audio power amplification system based on a ripple suppression circuit, which is characterized in that it is mainly composed of a preamplifier circuit, a triode VT2, a current limiter, and the positive pole is connected with the preamplifier circuit, and the negative pole is connected with the current limiter. Capacitor C3 connected to the input terminal, resistor R5 connected to the collector of the triode VT2 at one end and grounded at the other end, a ripple suppression circuit connected to the emitter of the transistor VT2, a power amplifier circuit connected to the ripple suppression circuit, and positive pole It is composed of a capacitor C4 connected to the preamplifier circuit, and the negative electrode is connected to the power amplifier circuit. The invention can filter the ripple voltage, thereby reducing the electromagnetic noise of the system and improving the stability of the system.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an audio power amplification system based on a ripple suppression circuit. Background technique [0002] As people pursue higher and higher quality of life, home theater has basically entered every household, which brings great joy to people's life. High-definition sound quality can improve the viewing effect, so the audio power amplification system used in the home theater is particularly important. However, when the traditional audio power amplification system amplifies the audio signal, it is easy to cause distortion of the audio signal, which largely affects the quality of sound playback. Contents of the invention [0003] The object of the present invention is to overcome the defect that the traditional audio power amplifying system easily causes audio signal distortion when amplifying the audio signal, and provides an audio power amplifying system based on a ripple suppression...
