摘要
A digital PFC circuit with improved power factor is described. The digital PFC circuit uses a compensation current generating unit and a reference current adjust unit to eliminate the effect of a current flowing through an input capacitor to the input current, so that the input current and the input line voltage of the digital PFC circuit are controlled to be in-phase.
