摘　　要：由于松耦合旋转变压器存在较大气隙,其电感量难以计算,为了省去计算机建模和仿真的步骤,缩短设计时间,针对壶型磁芯和邻近型线圈组成的松耦合旋转变压器建立磁阻模型,根据其大气隙的特点,采用磁阻分析的方法得到其等效电路模型.再以磁芯和线圈的尺寸为参数,分析、推导得出松耦合旋转变压器励磁电感和漏感的计算公式,并根据设计参数间的关联,给出了一个设计流程图.最后通过计算、仿真和实验三者对比分析,验证了励磁电感和漏电感公式的正确性.The inductance of loosely coupled rotating transformer is difficult to calculate because of a rel- atively oarge air gip. For shortening the design cycle and reducing the step of modeling and simulation, the reluctance model of loosely coupled rotating transformer with pot core and adjacent winding was built and analyzed, and the electric equivalent circuit is also presented. Formulas for calculating magnetizing inductance and leakage inductance was derived based on dimension of the pot core and the coil. According to the relation among parameters, a practical flowchart of design was given. It shows that the comparison results of calcula- tion, simulation and experiment verify the accuracy of predicted results from the formulas for magnetizing in- ductance and leakage inductance.
