High-voltage tapped-inductor buck converter auxiliary power supply for cascaded converter submodules
2012 (English)In: 2012 IEEE Energy Conversion Congress and Exposition, ECCE 2012, IEEE , 2012, 19-25 p.Conference paper (Refereed)
This paper firstly presents a discussion of the requirements for an auxiliary power supply for high-power modular multilevel converter submodules. Next, some of the most challenging problems in designing a low power high voltage step-down converter are presented. Further, a suitable topology, the tapped-inductor buck converter, that overcomes most of the problems is analyzed. Both analytical expressions describing the operation and circuit simulations are presented. Finally, an experimental evaluation of a 3 kV, 100W prototype converter utilizing an autonomous high-voltage switch is presented.
