单片机设计的实例电源技术尤其是数控电源技术是一门实践性很强的工程技术,服务于各行各业。电力电子技术是电能的最佳应用技术之一。当今电源技术融合了电气、电子、系统集成、控制理论、材料等诸多学科领域。随着计算机和通讯技术发展而来的现代信息技术革命,给电力电子技术提供了广阔的发展前景,同时也给电源提出了更高的要求。随着数控电源在电子装置中的普遍使用,普通电源在工作时产生的误差,会影响整个系统的精确度。电源在使用时会造成很多不良后果,世界各国纷纷对电源产品提出了不同要求并制定了一系列的产品精度标准。只有满足产品标准,才能够进入市场。随着经济全球化的发展,满足国际标准的产品才能获得进出的通行证。数控电源是从80年代才真正的发展起来的,期间系统的电力电子理论开始建立。这些理论为其后来的发展提供了一个良好的基础。在以后的一段时间里,数控电源技术有了长足的发展。但其产品存在数控程度达不到要求、分辨率不高、功率密度比较低、可靠性较差的缺点。因此数控电源主要的发展方向,是针对上述缺点不断加以改善。单片机技术及电压转换模块的出现为精确数控电源的发展提供了有利的条件。新的变换技术和控制理论的不断发展,各种类型专用集成电路、数字信号处理器件的研制应用,到90年代,己出现了数控精度达到0.05V的数控电源,功率密度达到每立方英寸50W的数控电源。从组成上,数控电源可分成器件、主电路与控制等三部分。目前在电力电子器件方面,几乎都为旋纽开关调节电压,调节精度不高,而且经常跳变,使用麻烦
