| Abstract |
The paper presents a comparison of four converter topologies for three-phase, high-frequency
switching, active Power Factor Correction. The selected topologies are: the series-connected dual
Boost rectifier with single DC rail, the series-connected dual Boost rectifier with split DC rail, a
Boost rectifier using an asymmetrical half-bridge, and the Vienna rectifier. The comparison is based
on the voltage stress of the switches and on the analytical calculations of the current stress of the
components, results that are also used to determine the switch utilization factors. |
