Starting strategies were investigated for a three-phase single-stage power factor correction (PFC) convetter. Starting process and mechanism of input over current was analyzed in detail. A lossy method was proposed and designed in which a resistor was connected in series with the filter capacitor to increase effective value of output voltage. Based on them, the boost inductors were replaced by central-tapped inductors with flyback windings, and a lossless starting strategy was proposed. Experimental results prove the validity and feasibility of the proposed methods.

PL

Przeanalizowano strategie startu trójfazowego przekształtnika do korekcji współczynnika mocy PFC. Zaproponowano metodę w której rezystor połączony jest szeregowo z pojemnością filtru w celu zwiększenia napięcia wyjściowego. Cewka została zastąpiona cewką z zaczepami umożliwiającej zmianę uzwojeń. Zaproponowano bezstratną strategię startu.
