Design guidelines for wound Inter-Phase Reactors in high-power rectifier systems

This paper reviews the design procedure of wound-type Inter-Phase Reactors used in high power rectifier systems, and gives some guidelines for an optimized sizing aimed at minimizing costs and active mass. In particular, the paper proposes a design algorithm to identify the optimal number of coils and turns and clarifies the role of the air-gap in minimizing the magneto-motive force unbalance and affecting the column peak flux density.
