Abstract

This contribution describes three procedures and the related software operations which are used to obtain the pulse-width modulation (PWM) signal for industrial use. The hardware platforms used to generate the signals are embedded systems, manufactured in recent years. Three types of microcontrollers based on their register architecture were used: 8-bit ATMEGA 328P, 16bit SAB80C167 and 32-bit PIC32MX320F128H. PWM is a preferred way for control in modern semiconductor devices. The very short rising and falling time ensure the minimum of switching transition time respectively of the switching losses. In this context, the paper will analyze comparatively a new structure, related on a classical reference structure, both the hardware and the software. At the end of the paper some conclusions might be drawn on the code length, system latency and the technical limitations of their usual or rated performance.
基于微控制器的多平台PWM信号生成工业用程序
该贡献描述了用于获得工业用脉宽调制(PWM)信号的三个程序和相关软件操作。用于产生信号的硬件平台是近年来制造的嵌入式系统。基于寄存器结构的三种类型的微控制器被使用:8位ATMEGA 328P, 16位SAB80C167和32位PIC32MX320F128H。PWM是现代半导体器件的首选控制方式。极短的上升时间和下降时间保证了开关损耗的切换时间最小。在此背景下,本文将在经典参考结构的基础上,从硬件和软件两个方面对一种新的结构进行比较分析。在论文的最后,可以得出一些关于代码长度、系统延迟以及它们通常或额定性能的技术限制的结论。
