G. Spiazzi et Fc. Lee, IMPLEMENTATION OF SINGLE-PHASE BOOST POWER-FACTOR-CORRECTION CIRCUITSIN 3-PHASE IMPLICATIONS, IEEE transactions on industrial electronics, 44(3), 1997, pp. 365-371
A three-phase rectifier employing three single-phase boost power-facto
r-correction circuits is analyzed, Each converter operates in the cont
inuous conduction mode (CCM), which allows a high power factor and a s
mall EMI filter, Current sharing is ensured by a common voltage loop d
riving the individual current loops of the three converters, A suitabl
e circuit arrangement is devised to limit phase interaction, The zero-
voltage-transition technique (ZVT) is successfully applied to each con
verter, in order to obtain zero turn-on losses and soft turnoff of the
freewheeling diodes, Results of a 1800-W 100-kHz experimental prototy
pe are reported, which confirm the theoretical forecasts.
