Abstract
A transformer includes an outer peripheral iron core, and at least three iron core coils, which are in contact with or coupled to the inner surface of the outer peripheral iron core. The at least three iron core coils each include an iron core, and at least one of a primary coil and a secondary coil, which are wound around the iron core. Gaps, which can be magnetically coupled, are formed between two adjacent ones of the at least three iron cores, or between the at least three iron cores and a central iron core positioned at the center of the outer peripheral iron core.
