变频器三相信号源发生器研究

On Three-phase Frequency Signal Generator

低频信号发生器作为信号源历来受到微电子技术的从业人员关注,三相低频信号源更是从事控制系统设计的工程技术人员首选工具。长期以来,人们一直试图通过电子线路制作三相低频信号源,可效果不尽人意。利用单片机作为三相低频信号源的核心部件不但保证了三相低频信号的完整、稳定,还能实现频率从0～50Hz的任意调节。利用单片机的定时器作为频率控制,利用单片机的输入输出口作为三相信号输出是设计的初衷,通过反复实验后认定利用单片机作为三相低频信号源的设计是可行。利用单片机作为三相低频信号源发生器的关键技术是程序设计,程序设计的核心的三相方波之间的相序和频率的可调性。

Low frequency signal generator has been a source of microelectronics technology personnel concerned;three-phase frequency signal is engaged in the design of control system of engineering and technical personnel.For a long time,people have been trying to make three-phase frequency signal circuit but the nesucts are unsatisfactory.Three-phase frequency signal microcontroller as the core parts not only ensure the three-phase frequency signal integrity,stability,also can realize frequency from 0 ~ isolator of arbitrary regulation.The microcontroller timer microcontroller as frequency control,the I/O port as three-phase signal output is designed,through repeated experiments confirmed by microcontroller as the three-phase frequency signal design is feasible.
