1 3-Phase Power Factor Correction, Using Vienna Rectifier Approach and Modular Construction for Improved Overall Performance, Efficiency and Reliability1 D. Pathak, Mr. Ralph E. Locher, Prof. Himanshu S. Mazumdar, Senior Applications Engineer, Director, Applications Engineering, Head, Computer Science Lab., IXYS Corp., Santa Clara, CA IXYS Corp., Santa Clara, CA Physical Research Laboratory, Ahmedabad-380009, INDIA Abstract: While applications for 1-Phase PFC are now familiar and prevalent, the same is not the case with 3-Phase PFC.
Figure 2. 3-Phase line voltages red, yellow and blue with 12 time segments From 0 through 11 4.4 Vienna Rectifier Modules Looking at Figure 1, it becomes apparent that if one were to assemble the entire 3-Phase Vienna Rectifier PFC circuit using discrete components, many different power semiconductors have to be connected together.
