This paper investigates methods of implementing a high-precision AC voltage control circuit using a transformer. An investigation was also made of the relationship between excitation parameters and the self-inductance of the winding as apparent to the excitation winding of the transformer. Concretely, the authors first demonstrate that the B-H loop apparent to the excitation winding varies with excitation parameters, and propose an approach for handling self-inductance. The proposed approach was applied to the analysis of an AC voltage control circuit, with the result that the calculated and actual controlled voltages were within ±0.15% error of each other. Based on these results, guidelines were developed for the handling of self-inductance when designing AC voltage control circuits with transformers.
