I gcás ionduchtais imoibriúcháin smúdála atá mór go leor sa taobh DC, is é seo a leanas voltas aschuir an chiorcaid ceartaíochta droichid iomlán trí chéim:
Ud ＝ 1.35 ua cos (1)
UD -------- Meánluach an aschuir voltais DC
UA -------- Voltas Líne Ionchuir an Droichid Ceartaitheora
{--------- Trigger Moill uillinn SCR
If the rectifier bridge input line voltage Ua is given, the size of the output DC voltage can be changed by change of the trigger delay angle of the tube so as to achieve the purpose of regulating the output power of the equipment. Because of the cosine(non-linear) relationship between Ua and a, the non-linear link is added in the microcomputer control triggering procedure, which plays a key role in the improvement of linearization regulation. In the event of a failure, the pulse a>Tá 90 céim faoi réir ag cosaint inverter a bhrú . Is féidir é a fheiceáil ón bhfoirmle (1) go bhfuil an UD diúltach . Sa chás seo, tugtar an stádas oibriúcháin inbhéartaithe air de dhroichead an droichid {. Is é an t -aiseolas a bhaineann le fuinneamh an fhuinnimh de réir ualach, nach gcuireann sé i bhfeidhm ar}}}}
