Class-D功放详解 Audio Class D Amplifier Introduction OUTLINE OUTLINE The Principle Of Class-D Amplifier Class-D Amplifier使用脉寬調製技術(PWM技術)用模拟信号的幅度来调制一系列矩形脉冲的宽度。这种脉宽调制是用一个等幅三角波来对音频信号进行采样来实现(如右)。经过采样后,模拟信号的幅度信息就被转换到脉冲...
The class AB amplifier can be designed by usingMOSFETto generate an output power of 100W to drive the 8 ohms load. This type of power amplifier is designed due to its high efficiency, less harmonic, and Cross-over distortion. The circuit diagram of a class AB amplifier using MOSFET is sho...

Class D amplifiers, first proposed in 1958, have become increasingly popular in recent years. What are Class D amplifiers? How do they compare with other kinds of amplifiers? Why is Class D of interest for audio? What is needed to make a “good” audio Class D amplifier? What are the ...
6雖然Class-DAmplifier的工作原理都是依靠PWM調製技術,但在具體採樣方式和時序上,各個廠商之間卻各不相同,以TI&PAM為例:右圖為TI廠商型號:TPA3110D2全橋輸出的波形。黃色曲綫和藍色曲綫分別為負載兩端對地的波形,紅色曲綫為黃色曲綫與藍色曲綫做減法運算得到的波形即負載的輸出波形。图3TPA3110D2全橋輸出的波形7图...
