Abstract
The theoretical advantage of Intel-Cell Transformers over separate inductors is demonstrated in an interleaved power converter. Different practical ways to build InterCell Transformers are described. A theoretical approach dedicated to interleaved converters and InterCell Transformers analysis is presented. This analysis tool is used to understand and overcome the main drawback of InterCell Transformers. It is shown how the phase shifts between two adjacent phases must be modified to reduce the maximum flux density that influences core sizing and core losses.
