Three-phase inductors are often used in filtering applications in three-phase ac power distribution systems. A variety of magnetic architectures can be used to implement these inductors. In this work, two studies are performed comparing four possible architectures — UI-, EI-, Y- and delta-core. The first study focusses on low-frequency steel-core inductors; the second study focuses on a high switching frequency application. Results show that Y-core and delta-core inductors offer reduced mass for a given loss in both cases.
