Abubuwan da ke rinjayar walƙiyar halin yanzu kula da daidaito na tsaka-tsakin tabo mai walƙiya

A cikin tsarin walda, saboda canjin juriya zai haifar da canjin walda, ana buƙatar daidaita yanayin walda a cikin lokaci. A halin yanzu, hanyoyin da aka saba amfani da su sun haɗa da hanyar juriya mai ƙarfi da tsarin sarrafawa akai-akai, da dai sauransu, waɗanda manufarsu ita ce kiyaye walƙiyar halin yanzu ta hanyar matakan sarrafawa. Saboda juriya mai ƙarfi yana da wuyar aunawa, aikin sarrafawa yana da wuyar aiwatarwa.

Saboda haka, Xiaobian rungumi dabi'ar m halin yanzu iko hanya don tattaunawa, da kuma da farko nazarin dalilan da ke kaiwa ga low waldi halin yanzu iko daidaito. A halin yanzu iko na matsakaici mitar tabo waldi inji, ta yin amfani da tsari na thyristor conduction Angle don sarrafa walda halin yanzu, kasar Sin tana amfani da 50Hz alternating current, da lokacin ne 20ms, kowane sake zagayowar yana da biyu rabin taguwar ruwa, kowane rabin igiyar ruwa ne 10ms, cewa shine, ana iya daidaita tsarin kusurwar ƙwanƙwasa thyristor kawai kowane 10ms.
