Multiphase PWM Signal Generator Model Design for Effective Class D Amplifier

This article describes the design of a multiphase pulse width modulation (PWM) signal generator model for use in a high-performance class D switching amplifier. Sigma-delta modulation (SDM) is used for additional mathematical processing. In this article architecture of proposed generator model and operation principles of each block are described. The influence of the order of the SDM and the number of phases of the multiphase PWM on the characteristics of the signal at the amplifier output using the developed model is investigated. It also considers the relationship between the clock frequencies of individual blocks, depending on the sampling rate of the input digital signal.
