| Abstract: | A new type of power converter for the cathode anticorrosion applied to oil gas pipelines is developed. Its circuit topology and operation principles are discussed. Also the operating process is analyzed and calculated by means of regulated state locus charts, and the relevant design formulas are derived. A kind of distinctive control methods are presented in accordance with the working characteristics of the converter. The constant potential apparatus developed for cathode protection on the basis of the converter is of high power, low ripple output and strong reliability. |
