KM531A工作原理图
KM531A 功能模块是指数据说明、可执行语句等程序元素的集合,它是指单独命名的可通过名字来访问的过程、函数、子程序或宏调用。
KM531A 功能模块化是将程序划分成若干个功能模块,每个功能模块完成了一个子功能,再把这些功能模块总起来组成一个整体。以满足所要求的整个系统的功能。
KM531A Function module refers to a collection of program elements such as data descriptions and executable statements. It refers to individually named procedures, functions, subroutines or macro calls that can be accessed by name.
KM531A Functional modularization is to divide the program into several functional modules, each functional module completes a sub-function, and then these functional modules are summed up to form a whole. to meet the required functionality of the entire system.

高频逆变式整流焊机电源是一种··能、·效、省材的新型焊机电源,代表了当今焊机电源的发展方向。由于IGBT大容量模块的商用化,这种电源更有着广阔的应用前景。
逆变焊机电源大都采用交流-直流-交流-直流(AC-DC-AC-DC)变换的方法。50Hz交流电经全桥整流变成直流,IGBT组成的PWM高频变换部分将直流电逆变成20kHz的高频矩形波,经高频变压器耦合, 整流滤波后成为稳定的直流,供电弧使用。
由于焊机电源的工作条件恶劣,频繁的处于短路、燃弧、开路交替变化之中,因此高频逆变式整流焊机电源的工作可靠性问题成为·关键的问题,也是用户·关心的问题。采用微处理器做为脉冲宽度调制(PWM)的相关控制器,通过对多参数、多信息的提取与分析,达到预知系统各种工作状态的目的,进而提前对系统做出调整和处理,解决了当前大功率IGBT逆变电源可靠性。
国外逆变焊机已可做到额定焊接电流300A,负载持续率60%,全载电压60~75V,电流调节范围5~300A,重量29kg。
