WebNov 12, 2024 · The model clearly relates the magnetic geometry to a lumped circuit model, allowing visualization of coupling relationships and magnetic flux in SPICE. The model is conducive to state space and transfer function analysis. The dynamic equations of the M-phase coupled inductor buck converter are derived. WebNov 29, 2014 · Coupled inductors are often used in multiphase topologies to take advantage of the current-ripple cancellation from magnetic coupling between the phases. Normally, current-ripple cancellation happens only at the output of the multiphase buck converter when typical discrete inductors are used.
