A common misconception is that a "bigger" core is always better. Maniktala highlights that core loss depends on frequency and flux swing (delta B).
While silicon carbide (SiC) and gallium nitride (GaN) transistors have emerged since the book’s publication, the physics of optimization remain unchanged. Maniktala’s work on parasitic inductance, thermal vias, and feedback loop compensation applies regardless of whether your switch is Silicon or GaN. A common misconception is that a "bigger" core
