摘要

针对直流无刷电机驱动系统存在的模拟PWM技术控制难、PWM芯片少以及PWM死区时间精度低等问题，本文采用Verilog语言设计了一款纯数字电路实现的PWM波形生成器.文中简要介绍了PWM在直流无刷电机系统的控制原理、电机转子位置和电机相导通的关系及PWM调制方式，重点描述了采用纯数字方法实现PWM波形发生器的设计流程.通过增加时钟除频模块，死区计数时钟频率可提高到PWM计数器的16倍；两通道PWM共用一个死区计数器，节省了设计资源.设计的PWM波形生成器可通过SPI接口进行参数配置，实现可编程、方便控制等优点.

Abstract

In view of the problems in the brushless DC motor drive system

such as the difficulty of analog PWM technology control

the lack of PWM chips and the low precision of PWM dead time

this paper designs a pure digital PWM waveform generator using Verilog language. This paper briefly introduces the control principle of PWM in brushless DC motor system

the relationship between motor rotor position and motor phase conduction and the PWM modulation mode

and emphatically describes the design process of PWM waveform generator using pure digital method. By adding a clock divider module

the clock frequency of dead-time counter can be increased to 16 times that of PWM counter. Two channels of PWM share a dead-time counter

saving design resources. The designed PWM waveform generator can be configured through SPI interface to realize the advantages of programmable

convenient control and so on.
