摘要
本文主要介绍的是通过普通电子元件设计出高效率音频功率发大器的方法。它不仅能够减少电路的成本,同时还能够将放大器的效率给提高。该设计中的PWM电路是由基本的运算放大器所构成,从而形成了能满足高效率,低失真要求的D类功率放大器。
This paper mainly introduces the method of designing a high efficiency audio power amplifier based on common electronic components.It can not only reduce the cost of the circuit,but also can improve the efficiency of the amplifier.The design of the PWM circuit is composed of the basic operational amplifier,thus forming a high efficiency,low distortion requirements of class D power amplifier.
