ABSTRACT II ABSTRACT In the modernized industrial enterprise, The electric power is one of the most main energy. But in the metallurgical industry, the electrochemistry industry, the hauling, the transmission, the direct current transmission and so on, in many professions the directcurrent power supply is widely utilized. Exchanging the alternating current to the direct current needs the rectifier unit, the rectification transformer is this rectifier unit. Therefore researching and designing rectification transformer have the profound significance. This topic union specifically is according to project parameters, mainly through to the rectification electric circuit design, the parameter putation, the iron core design, the coil design, the loss putation, the impedance voltage putation, the weights of the transformer and the ascension of temperature putation and so on. Designing a rectification transformer which is satisfied the actual project parameters and has practical application value. 【 Key words】 Power transformer, present situation, actual project parameter, design.目 錄 1 目 錄 摘 要 ................................................................................................................................
