Some studies reported that a converter utilizing PFC can reduce phase current and output voltage ripples, respond faster to load transients, and reduce the amount of output decoupling capacitance. To truly take advantage of the PFC technique, a clear understanding is needed of its limitations, of the effect of the coupling coefficient on the current distribution in each winding and on the overall regulator steady-state and transient performances, as well as of the specification of the coupling coefficient in order to meet certain performance.
