| Abstract: | According to the theory of Pseudo-Random Multi-Frequency Induced Polarization method and the technological requirements for the observation system, the authors have designed an intelligent controlling project used in WDD Pseudo-Random Multi-Function Electrical Transmitter. In this project, MCS-51 is used as the main control unit that can produce several kinds of current and IGBT is employed as the high power output unit which can generate maximum voltage 800 v, maximum current 40 A, and maximum power 6 kW. Having used in geological research work in Gansu, Shanxi and Yunnan provinces, the transmitter proves to be stable, secure and reliable. |
