As rectifier units are crucial equipment to provide energy for the Cu electrolysis plant, the reasonable selection of such units bears on the reliability and cost-effectiveness of corporate production. This paper expounded the determination of all important parameters of rectifier units, including primary side voltage of rectifier transformer, DC voltage of rectifier, the number of rectifier phase, the form of rectifier circuit, the connection mode of rectifier transformer and rectifier, and the capacity of rectifier transormer. In addition, this paper took a Cu electrolysis project as an example to conduct selection and parameter calculation of rectification devices.
