4. 高電壓型變頻器電路結構采用IGBT直接串聯技術，也叫直接器件串聯型高壓變頻器。其在直流環節使用高壓電容進行濾波和儲能，輸出電壓可達6KV，其優點是可以采用較低耐壓的功率器件，串聯橋臂上的所有IGBT作用相同，能夠實現互為備用，或者進行冗餘設計。缺點是電平數較低，僅為兩電平，輸出電壓dV/dtyejiaoda，xuyaocaiyongtezhongdiandongjihuozhengjiagaoyazhengxianbolvboqi，qichengbenhuizengjiaxuduo。tabujuyousixiangxianyunxinggongneng，zhidongshixulingxinganzhuangzhidongdanyuan。zhezhongbianpinqitongyangxuyaojiejueqijiandejunyawenti，yibanxuteshushejiqudongdianluhehuanchongdianlu。duiyuIGBT驅動電路的延時也有極其苛刻的要求。一旦IGBT的開通、關閉的時間不一致，或者上升、下降沿的斜率相差太懸殊，均會造成功率器件的損壞。
