Inductors combining ring cores and I cores

摘要

Inductors are usually realized with E, I cores and C core types. Some other construction types are also possible, using a combination of I cores and ring cores and cut ring cores. We designate them as OI, CIC, 41 and 61 (hexagonal) cores. We compare their weight for a given copper loss and a given reactive power. To check the design a hexagonal core was constructed.
