摘要
提出一种适用于油气集输管线阴极防腐保护特种电源的新型功率变换器,对其工作原理做了详细讨论,结合具体应用实例阐述一种简单实用的脉冲频率控制方法,给出了该恒电位仪的有关实验波形和输出外特性曲线。研制结果表明,采用零电流功率开关有利于降低开关损耗和提高变换器的容量与效率。
This paper proposes a new type power converter applied for the cathode anticorrosion of oil-gas-pipelines. Its circuit topology and operation principle are discussed. A kind of distinctive pulse frequency control method is presented in accordance with the working characteristics of the converter as a specific case. The experiment waveforms and output characteristic curves of the constant potential apparatus are gived. Research fruit make known,the apparatus developed for cathode protection on the basis of the zero current switch converter are of low switch loss ,high output capacity and efficiency.
