其直流回路濾波是電感。它由三部分構(gòu)成，將工頻電源變換為直流功率的“整流器”，吸收在變流器和逆變器產(chǎn)生的電壓脈動(dòng)的“平波回路”，以及將直流功率變換為交流功率的“逆變器“。整流器大量使用的是二極管的變流器，它把工頻電源變換為直流電源。也可用兩組晶體管變流器構(gòu)成可逆變流器，由于其功率方向可逆，可以進(jìn)行再生運(yùn)轉(zhuǎn)。平波回路在整流器整流后的直流電壓中，含有電源6倍頻率的脈動(dòng)電壓，此外逆變器產(chǎn)生的脈動(dòng)電流也使直流電壓變動(dòng)。為了電壓波動(dòng)，采用電感和電容吸收脈動(dòng)電壓（電流）。裝置容量小時(shí)，如果電源和主電路構(gòu)成器件有余量，可以省去電感采用簡(jiǎn)單的平波回路。逆變器同整流器相反，逆變器是將直流功率變換為所要求頻率的交流功率。
