A Comprehensive Study on Magnetic Materials Selection for Power Electronic Converters

The size and efficiency of converters are key considerations to ensure optimal power management across electrical networks, which significantly affect industrial, aeronautical, and automobile use. Frequently, the converter's most important component is the inductor. The appropriate inductor can eliminate the current ripple at the converter's input. Therefore, choosing the right component is crucial for a converter design. The operating frequency range of power converters is selected from 20 kHz to 150 kHz. Whenever the switching frequency is raised from 20 to 150 kHz, the converter volume shrinks by 59.5% and weight is lowered by 58.4%. This study compares the magnetic materials utilized in a realistic design. Iron-based amorphous metals, nanocrystalline, alloy-powdered, silicon steel and ferrite materials are among the substances under this research. The type of converters, magnetic materials, features and their shape selection are discussed. Finally, based on some prior research, we proposed that powdered material cores are the best choice for power electronic converters.
