Design of leakage current test system based on TMS320F2812

Leakage current is the most important parameter index in comprehensive test of electrical safety performance.To meet the need of designing multi-standard and multi-type leakage current test system,a leakage current test system based on TMS320F2812 is introduced.The principle and methods of leakage current test system are discussed,and the TMS320F2812 collects data and communicates with computer based on signal adjusting circuit of leakage current with single human body impedance networks are elaborated.The design and implementation of the whole test system is completed based on both hardware and software.Some experimental evidence and analysis of results are performed.Through researching the test system technology,it can greatly reduce the cost of the products and improve the test accuracy.It has significance for the level of leakage current test technology in our country.
