Hybrid Converter Topology for Power Factor Correction in DC Drives Applications
In this paper, the authors deal with a hybrid converter topology Power Factor Correction (PFC) for DC drives which is fed through a diode bridge rectifier from a single phase AC mains. In this paper, both buck and boost converter topologies are combined together and operated alternatively according to the rectified DC input voltage level. DC drives are mostly operating with variable load and variable speed. So, active PFC method is suitable for DC drives fed from the AC supply. In active PFC method, the buck and boost converters are most popularly used.
