The toroidal inductors are known for their higher flux densities, higher inductances, low losses in the windings, and less acoustic noise. This paper proposes novel concentric toroidal inductor configurations namely concentric toroidal inductors (CTI) used as power inductors and concentric toroidal differential-mode chokes (CTDMC) employed for DM noise filtration. The presented concentric toroidal structures provide improved inductances by utilizing the window area of the toroidal core. Analytical and experimental verifications prove the increment of inductance in CTI and CTDMI when compared to the corresponding traditional inductor confiaurations. © 2022 IEEE.
