Abstract
A multiphase power converter has a plurality of phase circuits, each of which provides a phase current when being active. During single-phase operation of the multiphase power converter, an enhanced phase control circuit and method monitor the summation of the phase currents, and when the summation becomes higher than a threshold, switch the multiphase power converter to a higher power zone to increase the number of active phases. A high efficiency and high reliability multiphase power converter is thus accomplished.
