摘　　要：从控制角α对变流电流的影响、控制角和换向重叠角与变压器阻抗的关系，得出了在深控时重叠角γ减小，导致交流电流谐波分量增加，增加了涡流损耗和附加损耗；而增大变压器阻抗可增大重叠角和减小损耗等．为设计变流变压器提供了理论依据和应用参数．Takong account of the effects of control angle on the converting current and the relations between the transformer impedances and the control angle, overlap angle, conclutions can be obtained that deep controlls of thyristors would make overlap angle decreasing, so that harmonics and losses increased. The rise of the tansformer impedances can increase overlap angle and decrease losses. It can be used as the basis for the design of the converting transformers.
