Abstract

Since the magnetic coupling exists between control windings of controllable reactor of transformer type（CRT）

the authors applied the decoupling magnetic integration technology to CRT structure design. The magnetic circuit with low magnetic resistance is provided to the magnetic flux of each control windings to realize decoupling between the control windings. Thereby

a magnetic integration structure of CRT core is proposed. The leakage inductance of each winding of this structure is calculated

its inductance-transformer equivalent circuit is established

and equation of coupling degree of control windings and no-load current with size of lateral column air gap are deduced

simulation analysis is carried out on MATLAB platform

and the results show that increase in the air gap can decrease the magnetic coupling between control windings and raise the utilization ratio of winding capacity

which verifies the effectiveness of the proposed magnetic integration structure of CRT core.
