Abstract：In this paper, a novel high-power controllable reactor based on magnetic flux compensating (CRMFC) is studied. For a transformer with air gaps, when the secondary current is controlled inverse in phase (or in phase) to the primary current, the reactance presented on the primary port will vary linearly with the amplitude ratio of primary and secondary current. To improve the power and voltage ratings, the multi-winding transformer is employed. In this paper, the theoretic equivalency of the multiple-winding and double-winding transformer working is proved, and the appropriate operating range of the reactor is discussed; meanwhile, a practical control scheme is proposed. A rated 6kV, 800kVar prototype is developed. The experimental results show that CRMFC has many advantages such as little harmonic, fast response, wide continuous-adjusting range, low loss etc.
