為有效控制固態功率調制設備,提高系統的可調性和穩定性,介紹了一種基于現場可編程門陣列( FPGA)和微控制器(MCU) 的多路高壓IGBT 驅動觸發器的設計方法和實現電路。該觸發器可選擇內或外觸發信號,可遙控或本控,能產生多路頻率、寬度和延時獨立可調的脈沖信號,信號的輸入輸出和傳輸都使用光纖。將該觸發器用于高壓IGBT(3300 V/ 800 A) 感應疊加脈沖發生器中進行實驗測試,給出了實驗波形。結果表明,該多路高壓IGBT驅動觸發器輸出脈沖信號達到了較高的調整精度,頻寬’脈寬及延時可分別以步進1 Hz、0. 1μs、0. 1μs 進行調整,滿足了脈沖發生器的要求,提高了脈沖功率調制系統的性能。
