Webdc.description.abstract. Multiphase interleaving buck converters are widely used in today's industrial point-of-load (POL) converters, especially the microprocessor voltage regulators (VRs). The issue of today's multiphase interleaving buck converters is the conflict between the high efficiency and the fast transient in the phase inductor design. WebCoupled inductors function in dc-dc converters by transferring energy from one winding to the other through the common core. They are available in many sizes, inductance values, and current ratings and most are magnetically shielded for low electromagnetic interference (EMI). The windings may have equal (1:1) or unequal turns ratios (1:N).
