| Abstract: | A detailed analysis on development process of regulated current supplies in earth resistivity measuring system is made. Technical indices and function of 2A,WL 5 and WL 5N regulated current supplies are evaluated.Detailed analysis and discussion on some technical problems in further development of the supplies are made. It is believed that the technique of high frequency switching supply ought to be applied in design of regulated current supply for measurement of earth resistivity. A main circuit of high frequency switching regulated current supply is given. |
