稳压电源性能测试仪研制

针对线性稳压电源的性能指标测试过程繁琐、测量结果不理想等问题，我们采用单片机技术实现了全自动测量，将测量中所需的自耦调压器、滑线变阻器、各种测量仪表（交流电压表、精密直流电压表、精密电流表、交流毫伏表）分别设计成智能仪表，自动输出和测量稳压电源需要的工频信号和输出的电压、电流信号，同时进行指标的计算，实时显示稳压电源的性能指标，根据需要可由微型打印机输出测量结果。

Development of Testing Instrument for DC Power Supply

Due to the troubles of numerous processes and unideal measuring results for testing the performance of DC power supply,a realization of automatical measurement using single chip computer is described in this paper.All the instruments required such as self-coupling booster,powerful rheostat,AC voltage meter,precision DC voltage meter,precision DC current meter,AC milli-voltage meter are designed as intelligent instruments.Power AC signal needed for DC power supply automatically outputs,the voltage outputs of DC power supply are also measured automatically,at the same time,the performance index of DC power supply under test is calculated and displayed on the LCD screen.The measuring results may be also printed by micro-printer if you need.
