此外，DV707系列變頻器開關(guān)電源的計(jì)劃仍是有區(qū)別與其它變頻器的本地。它選用了一塊型號為MA2810的集成塊，它集成了開關(guān)功率管，以及箝位穩(wěn)壓管等一些元器材于一體，使得開關(guān)電源的外圍電路減少了，但我們在修補(bǔ)中MA2810的損壞概率仍是比較高的。
（2）松下變頻器逆變模塊損壞
在VF—7F系列變頻器中，有時也會碰到逆變模塊的損壞。較多見的景象便是變頻器在正常工作中俄然失電，致使變頻器在從頭上電后無法發(fā)起電機(jī)。經(jīng)查看逆變模塊損壞，究其原因首要是因?yàn)橥ｋ姾笞冾l器還在工作指令的控制下，而此時因?yàn)殡姍C(jī)所帶負(fù)載的消耗及變頻器本身的消耗致使基地直流電壓急劇降低，簡略致使PWM調(diào)制波信號發(fā)作改動，致使功率模塊的損壞，通常在這種情況下，驅(qū)動電路是不簡略損壞的。更換逆變模塊，變頻器就能恢復(fù)正常工作。碰到此類情況，最佳可以在控制電路上采用措施，停電霎時間關(guān)閉變頻器輸出。
