In power electronic converters, magnetic components serve as core elements for energy storage, conversion, filtering, and electrical isolation, playing a pivotal role in determining converter performance. Magnetic components remain one of the primary limiting factors in achieving miniaturization, weight reduction, and power density enhancement of converters. Integrated Magnetics (IM) technology enables the integration of two or more discrete magnetic components (e.g., inductors, transformers) onto a single magnetic core, significantly reducing component count, volume, weight, losses, and costs while improving operational efficiency and power density. Key objectives of IM technology include:
* Reducing magnetic component quantity
* Minimizing maximum magnetic flux density through flux superposition/destruction
* Suppressing magnetic flux ripple to reduce core losses
* Optimizing magnetic flux distribution for improved performance metrics (e.g., input/output current ripple reduction, transient response enhancement)
