Back-to-Back NPC Switching Technique to Reduce Power Loss of Back-to-Back NPC System for Offshore Wind Farm 2013
Switching Technique to Reduce Power Loss of Back-to-Back NPC System for Off shore Wind Farm HongSeok-Jin
Mechatronics Engineering Cooperation Course Sungkyunkwan University
In this paper,3-LevelNPC is applied as Back-to-Back foroffshore wind farm topology using PMSG.In caseofapplying 3-LevelNPC,each switch can withstand higher voltage than existing 2-Levelinverter,but overallloss of power converters is dramatically increased because amount of switching elemenT is increased.Thus,new switching method issuggested for 3-LevelNPC VSC If suggested method is applied,loss in NPC is minimized.
