With the increasingly serious problem of energy shortage,the magnitude of loss becomes one of the important factors to affect the design and optimization of electromagnetic equipment.In this paper,a new-type magnetic integration structure of controllable reactor of transformer type(CRT)is taken as the research object,and its losses are analyzed and calculated.Based on the analytic calculation method,the loss calculation principle of the new-type magnetic integration CRT is analyzed and its loss calculation formula is derived.Based on the Finite Element Method(FEM),the finite element model of the new-type magnetic integration CRT is established,and the field-circuit coupling simulation and loss calculation are carried out.The loss calculation results of the two methods are compared and analyzed to show that the two methods have good consistency in the loss calculation of the new-type magnetic integration CRT.The method and calculation results adopted in this paper have certain theoretical guiding significance for the structure design and parameter optimization of magnetic integration CRT.
