Maitiro ekusarudza zvakanaka inverter zvikamu zve kudonhedzwa kunyorera vira

Kazhinji, pasi pemamiriro ekushanda pamusoro pe400HZ, KK zvishandiso zvinofanirwa kutariswa; kana frequency iri pamusoro pe4KHz, KA zvishandiso zvinogona kutariswa. Pano isu tinonyanya kusuma kusarudzwa kwezvikamu muparallel inverter circuit (ona Mufananidzo 1).

(1) The component mberi uye reverse peak voltage VDRM, VRRM chikamu mberi uye reverse peak voltage inofanira kuva 1.5-2 nguva chaiyo yepamusoro yepamusoro uye reverse peak voltage. Tichifunga kuti iyo DC yekupinda voltage yeiyo inverter iUd uye iyo simba chinhu cosψ, ipapo:

VDRM/RRM=(1.5-2)πUd/(2cosψ)

(2) Iyo yakarongerwa pa-state ikozvino IT (AV) yechikamu inofunga kuti kana chikamu chinoshanda pahuwandu hwepamusoro, kurasikirwa kwayo kwekuchinja kunokosha zvikuru. Iyo yakatemerwa pa-nyika ikozvino yechikamu inofanira kuyerera 2-3 nguva yayo inoshanda kukosha Ini maererano neiyo chaiyo Kufunga, kureva.

IT(AV)=(2-3)I/1.57

Tichifunga kuti inverter DC yekupinda ikozvino iId, yakasarudzwa mudziyo IT (AV) ndeye

IT(AV)=(2-3)×Id/(1.57)

(3) Kudzima-nguva tq Muchikamu chinotenderera chinotenderera, nguva yekudzima yeKK element inofanira kusarudzwa maererano ne-pre-trigger time tf uye nguva yekushandura tr. Kazhinji tora:

tq=(tf-tr)×

(Kana simba racho riri 0.8, tf inenge chikamu chimwe chegumi chenguva, tr inotarirwa nechinhu di/dt pasi kana kuenzana ne100A/μS) Kana iyo frequency yakakura, nguva yekuchinja tr inogona kuderedzwa uye zvakabayirwa zvakafanira Nzira yesimba chinhu wedzera tf kusarudza zvikamu zvine kukosha kwetq kwakakodzera
