討論雙管單端磁通復(fù)位問題
這是我做的逆變器,540V直流電壓輸入,副邊輸出20V,200A,下面是開關(guān)管波形和變壓器原邊電流波形,實(shí)際中當(dāng)開關(guān)管關(guān)斷,通過兩個(gè)二極管對變壓器進(jìn)行磁通復(fù)位,但是開關(guān)管關(guān)斷時(shí)候,原邊電流很快將為零,和書上說的開關(guān)管關(guān)斷時(shí)刻,原邊電流波形緩慢下降有點(diǎn)矛盾,逆變器工作正常,只是對磁通復(fù)位有點(diǎn)疑惑,給大家變壓器原邊和副邊波形看看,實(shí)現(xiàn)了磁通復(fù)位,但是和書上說的不一致亞
全部回復(fù)(3)
