摘　　要：目前常见的便携式核数据测量分析仪电源供应为单一的蓄电池供电方式,这不仅影响测量仪器的长时间连续正常工作,而且增加了系统的成本和体积。为此,以X荧光分析仪为例,提出了一种实用的由太阳能光伏电池和锂电池联合供电的便携式核测量仪器电源设计方案。介绍了系统组成及各部分对电源的指标要求,给出了锂电池充放电控制电路,设计了以SG1525为核心的PWM电源供电电路。实践表明,该方案满足设计要求,对于便携式核数据测量分析仪的电源设计具有实际应用意义。Accumulator is commonly used as power-supply of Portable-Type Nuclear Data Analyzer at present,which impose a limit on the Analyzer＇s working time and increase its volume and cost.Therefore,take X-ray fluorescence analyzer as example,a useful joint-power-supply consists of solar photovoltaic and lithium-ion cells is proposed.Discussing the composition of the system and requirements for each component,the paper presents a xontrol circuit for lithium-ion battery pack charging and discharging,and a PWM power-supply circuit based on SG1525.Practice indicates that the method satisfies the actual requirement,it is of great practical significance and can be used in Portable-Type Nuclear Data Analyzer.
