摘要
主要介绍了8路恒流/恒压电源的工作原理和设计特点,同时介绍了利用高精度、高密度PCI卡控制8路电源恒流/恒压输出的计算机实现过程,包括电源的软硬件设计、技术指标测试。此电源为四点法测试微动系统中8路接触对动态接触电阻提供恒流输入。
The working principle and design features of the eight-channel constant current/constant voltage（CC/CV） power supply were presented.The implementation of the eight-channel power supply controlled by PCI board of high density and high precision was introduced,including software design,hardware design,testing of parameters.The power supply was applied to testing contact resistance by four-point method in eight-channel fretting simulation system.
