摘要

In view of the present secondary dc power technology poor precision, the problem of low efficiency, the second dc power supply parameters test system is designed. The system USES the electronic load to realize the continuous adjustable secondary power load, USES the Lab Windows/CVI software development platform to complete the upper computer program development, and USES the ARM7 microprocessor to realize signal acquisition, processing and control of the electronic load, and its processing results are displayed and stored by the upper computer. By analyzing the experimental results, it is shown that the system can automatically test the technical parameters of secondary power supply, such as voltage deviation, load stability, voltage stability, efficiency, transient response and ripple coefficient.
