Several types of magnetic devices, their B-H loops, and core vs. copper loss A key design decision: the choice of maximum operating flux density Bmax Choose Bmax to avoid saturation of core, or Further reduce Bmax , to reduce core losses Different design procedures are employed in the two cases. Types of magnetic devices: Filter inductor Conventional transformer Flyback transformer Magnetic amplifier Ac inductor Coupled inductor SEPIC transformer ……
