多相耦合电感蝶形交错绕组布置

Multiphase coupled inductors in pulse-width modulated (PWM) converters benefit from the reduced steady-state current ripple and fast transient performance. This article proposes a magnetic core geometry together with a butterfly interleaving winding arrangement to integrate the four-phase negative coupled inductors. It adopts the interleaving winding strategy usually used in planar transformers to...
