Ikhadi lempendulo ye-GE IS200DSFCG1AEB Driver Shunt
I-IS200DSFC 1000/1800 A IGBT Gate Driver/Shunt Feedback Board (DSFC) iqukethe izifunda zamanje zokuzwa, ukutholakala kwamaphutha, namasekhethi amabili okushayela amasango e-IGBT. Amasekhethi omshayeli kanye nempendulo ahlukaniswe ngogesi nangokukhanya.
Ibhodi yakhelwe umndeni osha wamabhuloho angu-1000 A kanye no-1800 A we-pulse wide modulated (PWM) namadrayivu e-AC. Ibhodi le-DSFC lihlangana nokulawula kokushayela nge-IS200BPIB Drive Bridge Personality Interface Board (BPIB). Ibhuloho lomthombo we-1000A noma umshayeli udinga amabhodi e-DSFC amathathu, elilodwa ngesigaba ngasinye. Ibhuloho lomthombo we-1800A noma umshayeli udinga amabhodi e-DSFC ayisithupha, amabhodi amabili e-DSFC "ochungechunge" ngesigaba ngasinye.
I-DSFC (G1) yakhelwe izinhlelo zokusebenza zedrayivu/umthombo okokufaka kwe-AC okungu-600VLLrms. Amabhodi e-DSFC agibeleka ngokuqondile kumamojula e-IGBT aphezulu naphansi emlenzeni wesigaba ngasinye ukuze kugcinwe ukuphuma kwedrayivu kanye nokuxhumeka kokufaka kwe-shunt kufushane ngangokunokwenzeka. Ibhodi lesifunda lilungiswa ngokuxhuma esangweni, i-emitter kanye nomqoqi we-IGBT. Ukuze kutholwe isango, i-emitter kanye nezimbobo zokuqoqa umqoqi, ibhodi lesifunda kufanele libekwe kahle.
Ibhodi le-DSFC liqukethe ipulaki nezixhumi zokubhoboza, izixhumi zembobo ekhwezayo (ukuxhuma kuma-IGBT), nezikhombisi ze-LED njengengxenye yebhodi. Azikho izinto zehadiwe ezilungisekayo noma amafuse njengengxenye yebhodi. Izintambo ze-DC exhumanisa amandla kagesi kanye nesigaba sokuphumayo zixhunywe kumatheminali okubhoboza. Konke ukuxhumeka kuma-IGBT kwenziwa ngezimbobo ezikhwezwayo ebhodini le-DSFC ngehadiwe ekhwezwayo.
Ukunikezwa kwamandla kagesi
Uhlangothi lwamandla kagesi aphezulu lwesekethe yomshayeli/yeqapha ngalinye lunikwa amandla yi-isolation transformer.
Okuyisisekelo kwalesi siguquli sixhunywe esiqongweni esingu-±17.7 V (35.4 V ukuphakama kuya esiqongweni), igagasi lesikwele esingu-25 kHz. Ababili kwabathathu abasekelayo balungisiwe futhi bahlungwa ukuze banikeze i-+15V (VCC) ne- -15V (VEE) ehlukanisiwe (engalawulwa, ± 5%*, 1A isilinganiso esiphezulu se-voltage ngayinye) edingwa umshayeli we-IGBT ophezulu naphansi. izifunda.
Ibhodi le-DSFC liqukethe iheda nezixhumi zokubhoboza, izixhumi zembobo ekhwezayo (zokuxhuma kuma-IGBT), nezinkomba ze-LED. Azikho izinto zehadiwe ezilungisekayo noma amafuse ebhodini. I-DC ixhumanisa izintambo zikagesi kanye nesigaba sokuphumayo sezintambo ze-voltage zixhuma kumatheminali okubhoboza. Konke ukuxhumeka kuma-IGBT kwenziwa ngokusebenzisa ihadiwe efakwayo ngezimbobo ezifakwa ebhodini le-DSFC.
Isesibili sesithathu silungisiwe ngokugcwele futhi sahlungwa ukuze sinikeze amandla kagesi wokuhlukanisa angu-±12 V adingekayo ku-oscillator elawulwa yi-voltage elawulwa yi-shunt yamanje namasekhethi okuthola amaphutha (okungalawulwa, ±10%, 100 mA isilinganiso esiphezulu ngasinye). Isekethe ye-shunt nayo idinga ukunikezwa okunengqondo okungu-5 V (±10%, 100 mA isilinganiso esiphezulu), ekhiqizwe isilawuli somugqa esingu-5 V esixhunywe ku-+12 V. Ukunikezwa kwe-5 V kuphela kulawulwa.
Ubuningi bemithwalo bumi kanje:
±17.7V 0.65A rms
+5V 150mA
Imibuzo evame ukubuzwa ngomkhiqizo imi kanje:
-Liyini i-GE IS200DSFCG1AEB Drive Shunt Feedback Card?
-I-IS200DSFCG1AEB iyikhadi lempendulo ye-drive shunt esetshenziswa ezinhlelweni zokulawula i-Speedtronic turbine. Iklanyelwe ukuphatha impendulo evela ku-exciter (noma ijeneretha), ilawula amandla erotha ye-turbine. Le mpendulo ibalulekile ekugcineni isivinini esilungile nokusebenza kwe-turbine ngokulungisa ukuphuma kwe-exciter ngokusekelwe ekusebenzeni kwangempela kwe-rotor.
-Yimiphi imisebenzi esemqoka ye-IS200DSFCG1AEB?
Icubungula amasignali asuka ku-turbine exciter noma ijeneretha ukuze kuqinisekiswe ukuthi impendulo efanele inikezwa ohlelweni lokulawula. Ikhadi lisiza ukuphatha ukulawulwa kwamandla kagesi ngokunikeza impendulo evela kumjikelezo we-exciter shunt ukuze kugcinwe ukuphuma kukagesi kwe-turbine ebangeni eliphephile. I-IS200DSFCG1AEB ibeka amasiginali ukuqinisekisa ukuthi afanele ukusetshenziswa wuhlelo lokulawula i-turbine. Futhi inomthwalo wemfanelo wokuqapha i-exciter kanye nejeneretha amaphutha noma amanani angaphandle kobubanzi, ukuhlinzeka ngokuvikeleka kwesistimu kagesi ye-turbine. Ikhadi lixhumana nayo yonke isistimu yokulawula i-turbine, iqinisekisa ukusebenzisana okufanele phakathi kwesivinini se-turbine, umthwalo, nokuphuma kukagesi.
-Iziphi izingxenye eziyinhloko ze-IS200DSFCG1AEB?
I-microcontroller/processor icubungula amasignali empendulo.
Izihlungi zesekethe yesimo sesignali futhi ibeka amasignali empendulo engenayo kusilawuli se-turbine.
Izixhumi namatheminali asetshenziselwa ukuxhumana ne-exciter nezinye izakhi ohlelweni lukagesi lwe-turbine.
Izibani zezinkomba zisetshenziselwa ukuqapha isimo, ukubika amaphutha, nokuxilongwa.
Izimbobo ze-Input/Output (I/O) zisetshenziselwa ukuxhumana namanye amamojula okulawula kusistimu yokulawula i-turbine.
