| 1 | IGCT——更高功率处理能力的正确选择显示文摘IGCT被视为大功率应用的理想开关器件,其主要优势不仅体现在高可靠性上,同时,其低损耗使得系统损耗较低。在三电平拓扑中,IGCT与目前最高水平的IGBT在器件损耗方面的对比结果为IGCT的较低。由于IGCT器件是基于晶闸管特性,系统中独立的箝位电路设计是必须的,以实现其与续流二极管配合工作时的高可靠性。文中不仅提到了对故障现象的特别考虑,重点介绍了外围电路设计和故障电流保护策略,而且介绍了IGCT目前最新的研发成果。在朝更大功率容量方向发展方面,IGCT器件具有很大的潜力。 | Thomas Stiasny Vasileios Kappatos Thomas Setz Sven Klaka Makan Chen Madhan Mohan | 2015 | 大功率变流技术2015，0，6： | 8 |

| 3 | HiPak 6.5kV IGBT的开关特性及门极驱动电路对其影响显示文摘介绍了ABB对Hi Pak 6500V/750A IGBT模块反向恢复特性的研究,首创性地就di/dt对二极管和与之反向并联的IGBT的正、反向恢复特性的影响进行了研究;并分析了di/dt对IGBT模块的影响,可以确认di/dt在其反向恢复过程中起重要作用,即当di/dt过高时,IGBT和二极管芯片会发生损坏,并有可能随后导致变流器的桥臂间短路。文章指出IGBT和门极驱动之间的优化匹配对确保安全工作十分重要,只有这样Hi Pak模块的鲁棒性才能得以完全体现。 | Makan Chen Raffael Schnell Evgeny Tsyplakov Arnost Kopta Joerg Berner 洪鹏 王浩 Sven Klaka | 2015 | 大功率变流技术2015，，2： | 1 |

| 5 | New Generation High Current Low Losses Thyristors for UHVDC Applications显示文摘New six-inch phase control thyristor(PCT)platform with enhanced current handling capability has been developed to enable an optimal design of converter valves for next generation Bulk power transmission.Silicon(Si)resistivity and wafer thickness of PCT are optimized to fulfil the demands laid on blocking capability while increasing the rated current.The parameters of electron irradiation are optimized for the best technology curve between the on-state voltage drop and reverse recovery charge.A narrow reverse recovery charge band has been identified for a safe voltage sharing in series connection with minimal demands on redundant PCT.Full utilisation of six-inch wafer and the optimized layout of cathode(snow-flake design)improves the on-state current ratings by nearly 20%compared to prior art thanks to the reduced on-state voltage by 10%.The on-state current rating for 7.2 kV device is up to 6.25 kA.The surge current capability increased by 30%and maximum surge current up to 63.5 kA is qualified for the 7.2 kV/6.25 kA device under the same test condition with improved packaging and reduced on-state voltage.Together with 30%lower value of circuit commutated recovery time,the new thyristor platform enables more efficient,powerful and stable converter valves for next generation ultra high voltage direct current transmission(UHVDC)systems with rated power beyond 10 GW. | LIU Chun-lei Jan Vobecky Urban Meier Makan Chen MA Jun DU Kai | 2016 | 电力电子技术2016，50，7： | 0 |
