This article introduces the technique indicators and working principles of rectifier diode intelligent surge current tester. According to the national standards of testing rectifier diode surge current, also to adapt the special indicator requests of overseas manufacturers, this intelligent control system composed of Single Chip Computer, D/A and A/D conversion. It discusses the production of the two kind of surge current waves, the number of the waves and the magnitude of the surge current. Meanwhile, after the rectifier diode has been tested through surge current, the technical parameters such as the actual current waveform and its magnitude have been designed, examined and data processed. Then the actual surge current value will be expressed by number on the instrument board. Finally, the testing method and error analysis have been provided. In practice, it is proved that this tester is an economical, applied new generation testing device used to test relevant technical parameters, and has been achieved practical application.
