【摘要】：高壓絕緣柵雙極型晶體管(IGBT)模塊直接串聯(lián)技術(shù)是實(shí)現(xiàn)柔性直流輸電、高壓直流斷路器等高壓大功率控制設(shè)備的一個(gè)重要基礎(chǔ),其中最難解決的是串聯(lián)IGBT模塊之間的電壓均衡問(wèn)題。文中分析了電壓不平衡的機(jī)制,得出了實(shí)現(xiàn)電壓均衡的關(guān)鍵在于解決斷態(tài)電壓不平衡和關(guān)斷電壓不平衡問(wèn)題,門極側(cè)均衡控制方法是較好的解決手段。對(duì)基于有源電壓控制技術(shù)的驅(qū)動(dòng)設(shè)計(jì)和基于延時(shí)補(bǔ)償?shù)目刂撇呗赃M(jìn)行了探討,并分別采用在有源區(qū)對(duì)關(guān)斷波形進(jìn)行跟隨控制和補(bǔ)償IGBT器件間關(guān)斷延時(shí)的方法,有效實(shí)現(xiàn)了串聯(lián)器件的電壓均衡。最后,通過(guò)6只3 300V/1 200AIGBT模塊直接串聯(lián)的閥段脈沖和基于該閥段的三相換流閥運(yùn)行測(cè)試,對(duì)這兩種方法進(jìn)行了驗(yàn)證,所述方法獲得了較好的電壓均衡效果。
[Abstract]:High voltage insulated gate bipolar transistor (IGBT) module is an important foundation for realizing high voltage and high power control equipment, such as flexible DC transmission, high voltage DC circuit breaker and so on.One of the most difficult to solve is the voltage equalization between series IGBT modules.In this paper, the mechanism of voltage unbalance is analyzed, and the key to realize voltage equalization is to solve the problem of off-state voltage imbalance and turn-off voltage imbalance. The gate side equalization control method is a better solution.The driving design based on active voltage control technology and the control strategy based on delay compensation are discussed, and the methods of following the turn-off waveform in the active region and compensating the turn-off delay between IGBT devices are adopted respectively.The voltage equalization of series devices is realized effectively.Finally, the operation tests of six direct series pulse valves with 3 300V/1 200AIGBT modules and three phase converter valves based on the three phase converter valve are carried out, and the two methods are verified, and the results of voltage equalization are satisfactory.
