AC/DC Product Portfolio

The front end three-phase PFC might be implemented in multiple topologies. Mainly it can be distinguished between two-level and three-level which will influence the design and the blocking voltage rating of the semiconductors. Three-level topologies are an appealing solution for engineers seeking high efficiency at low costs. An overview about existing common three-level PFC topologies can bee seen in the below graph.

Figure 1. Common three-level PFC topologies

Costs and efficiency have been benchmarked to illuminate the topologies' strengths and weaknesses. Another focus has been put on the comparison between Si and SiC diode

  • NPFC is outperforming in terms of efficiency, but has also the highest cost because of the 1200 V components.
  • SPFC and ANPFC topologies' efficiencies are nearly the same, given the same component technologies. However, ANPFC requires just one gate-driver which reduces the overall system’s cost, showing the best trade-off between performance and costs.
