“…This is not the case for three-level NPC converter. The outer IGBTs are more stressed during inverter operation while the inner IGBTs are more stressed during rectifier operation [4], [10]. As to the diodes, the outer diodes are stressed more during rectifier operation.…”

“…Trong [2] [3], [4] các tác giả đã đưa ra phương pháp phân phối nhiệt đồng bộ bằng cách thêm vào các IGBT mắc song song với các đi-ốt nối với điểm trung tính. Nghiên cứu này không can thiệp vào cấu trúc phần cứng của biến tần mà điều chỉnh phần mềm điều khiển của DTC nhằm mục đích khảo sát và phân phối lại công suất tiêu hao từ những IGBT hoạt động với tần số cao hơn tới các IGBT có tần số thấp hơn.…”

“…The objective of the proposals in [3][4] [5] is an homogeneous distribution of the losses under normal operation of the inverter. For this purpose, the topology of the inverter is modified by adding IGBTs parallel to the neutral point diodes to generate additional redundant states of switching states 0 (connection of one of the output phases to the neutral point).…”
