摘　　要：电压源电流源是电气测量和精密计量中经常使用的基本部件或仪器,例如在电能表检定中就离不开由电压源和电流源组成的功率源,在其设计和制作中或在使用和操作中也经常遇到,对于各种负载应该如何确保源与负载之间处于最佳匹配状况的问题,是学者们经常探讨的问题。针对电压源和电流源匹配的问题,比较突出的电源在大功率阻性负载有功功率输出和感性容性负载无功功率输出条件下,所遇到的匹配状况问题进行一些初步探讨。Voltage source and electric current source are that electric measurement composes in reply a component or instrument measuring the basic being hit by frequent usage precisely, they can＇t be seprated from the power source being composed of voltage source and electric current source for instance right away in electric energy meter calibration, before it＇s design be hit by with fabri- cation or be come across also often in usage and operation, ought to how to ensure a source and be in best match situation problem between the loads to various loads, that were being frequent investigation and discussion of scholars. The problem specifically for the voltage source mates with electric current source, comparatively outstanding power source under high-power hinder nature loads from having performed meritorious service the power output is loaded with the idle work power output with perceptual Rong nature condition, what become across matching status problem carries out some preliminary investigation and discussion.
