摘要

本文提出了一种确定死区时间对D类音频放大器谐波失真影响的解析方法。该分析基于已建立的双傅立叶级数，提供了自然采样下脉宽调制光谱的精确解析解。所提出的分析模型不同于以前的工作，因为可以确定每个单独分量的精确贡献，即基频、基带、载波和边带谐波。

A detailed analysis of the effect of dead time on harmonic distortion in a class D audio amplifier

This paper presents an analytical method for determining the effect of dead time on harmonic distortion in a class D audio amplifier. The analysis is based on the well established double Fourier series, providing accurate analytical solutions to the pulse width modulated spectra under natural sampling. The proposed analytical model differs from that of previous work in the sense that the precise contribution of each separate component can be determined, i.e. the fundamental component, baseband, carrier and sideband harmonics.
