【摘要】：壓接型IGBT器件以其耐受電壓高、電流密度大、控制功率低、開關速度快以及雙面散熱等優(yōu)勢成為柔性直流輸電系統(tǒng)中換流閥和直流斷路器選用的理想器件。由于應用裝備的差異,換流閥和直流斷路器對于壓接型IGBT器件分別提出了低通態(tài)壓降和高短路關斷能力的要求。分析了換流閥用壓接型IGBT器件和直流斷路器用壓接型IGBT器件外部和內(nèi)部電流、電壓、溫度和壓力的差異,總結了兩種器件應用過程中可能存在的主要失效原因,提出了封裝設計中需要重點考慮的技術問題。
[Abstract]:Because of its high withstand voltage, high current density and low control power, the voltage-connected IGBT device has the advantages of high voltage tolerance, high current density and low control power. The advantages of high switching speed and double-sided heat dissipation are ideal devices for the selection of converter valves and DC circuit breakers in flexible direct current transmission systems. The requirements of low on-state voltage drop and high short-circuit turn-off capacity for voltage-connected IGBT devices are proposed for converter valves and DC circuit breakers respectively. The external and internal currents and voltages of voltage-connected IGBT devices for converter valves and IGBT devices for DC circuit breakers are analyzed. The differences between temperature and pressure are summarized, and the main failure reasons in the application of the two devices are summarized, and the technical problems that need to be considered in the packaging design are put forward.
