I-WZD22005-5 22010-5 imojuli yokushaja imvamisa ephezulu
Uhlolojikelele lomkhiqizo
Le nkampani igxile ekukhiqizeni amamojula okushintsha ama-high-frequency switch kanye namanye amamojula wamandla ochwepheshe, kanye nezinhlelo zokuqapha ukunikezwa kwamandla kagesi, futhi inikeza izingxenye zokunikezwa kwamandla kubakhiqizi abahlukahlukene bokubambisana nabasebenzisi bokugcina.Uhlelo lokuphakela amandla okusebenza kwamandla luwumshini wokuphakela amandla egumbini lokufaka isicelo.Ikakhulukazi esetshenziswa eziteshini ezingaphansi (iziteshi) kuwo wonke amazinga kanye nezitshalo zamandla ashisayo, izitshalo zamandla kagesi, njengokunikezwa kwamandla okulawula umthwalo nomthwalo wamandla kanye nomthwalo wokukhanyisa ingozi ye-DC, kuyisisekelo sokulawula nokuvikela uhlelo lwamandla.Emkhakheni wezokuthutha ngojantshi, isetshenziswa kakhulu ukuhlinzeka amandla kagesi e-DC angaphazamiseki ekuvuleni nasekuvaleni ama-breaker circuit ohlelweni lokuphakelwa kwamandla kanye namathuluzi, amamitha, ukuvikelwa kokudlulisa kanye nokukhanyisa kwengozi kusekethe yesibili.
Uhlelo oluhlakaniphile lokushintshwa kwemvamisa ephezulu ye-DC luqukethe ingxenye yokusabalalisa amandla okufakwayo e-AC, ingxenye yokulungiswa kwemojula yokushaja, ingxenye eyehlayo, ingxenye yokuphakelayo ephumayo ye-DC, ingxenye yokuqapha kanye nengxenye yokuqapha ukwahlukanisa.
Umdwebo wohlelo lwesistimu
Izici Zomkhiqizo
Njengengxenye ebalulekile nebalulekile yesistimu yamandla, imojula yokushaja amandla okusebenza kwamandla iklanyelwe ukunikeza amandla kumpahla yamandla ngokuphepha, ngokuthembekile, ngokuyikho, ngokuzinza nangokungaphazamiseki;ngaphezu kwalokho, amandla esimanje okusebenza kwamandla kumele futhi abe nokuqapha okusabalaliswe ngo-Intelligent, imisebenzi yokuphatha ibhethri engagadiwe futhi ezenzakalelayo, ukuze kuhlangatshezwane nezidingo zokuphathwa kwesimanje kwezinhlelo zamandla.Imojula yokushaja kagesi esebenza ngamandla ayikwazi nje ukuhlangabezana nezidingo zemakethe, kodwa futhi ihlinzeka amakhasimende ngesisombululo sesistimu esiyonga ngempela, esithembekile futhi esikahle ngokombono wohlelo lokusebenza olungokoqobo lwamakhasimende.
Izici zayo eziyinhloko zifakwe ku:
■ Ukuminyana kwamandla aphezulu kusiza ukonga isikhala sohlelo futhi kwandise umthamo wesistimu.
■ Ukusebenza kahle okuphezulu, kusetshenziswa indlela ehlakaniphile yokupholisa umoya, kungaphatha kahle ukunyuka kwezinga lokushisa kwamadivaysi emojula futhi kuthuthukise ukwethembeka.
■ Inomsebenzi wokulungiswa okushelelayo kwe-voltage ephumayo kanye neyamanje.
■ I-anti-backflow diode ihlanganiswe ngaphakathi kwemojuli, ekwazi ukubona ukushintshaniswa okushisayo, okulungele ukulungiswa nokugcinwa kwesistimu.
■ Ukwabelana kwamanje kwesoftware, ngaphandle kwezilungiselelo zehadiwe, kungasekela amamojula angafika ku-0 ukuze asebenze ngokwethembeka nangokuzimele.
■ Imojula yokushaja ilawulwa ngobuhlakani futhi inikeza isikhombimsebenzisi sokuxhumana kwedatha.
■ Uhlelo lokuqapha olunamazinga amaningi ukuze kutholakale uhlelo lokuqapha olulula noluthembekile.
Amandla we-AC wezigaba ezintathu afakwa kusekethe esilungisa kabusha ngesihlungi se-EMI, i-AC ilungiswa ibe okokukhiphayo kwe-DC, futhi i-DC edonsayo iguqulwa ibe ugesi oqondile we-DC ngokusebenzisa isekethe yokulungiswa kwesici samandla (i-PFC).Isiguquli se-DC/DC sikhiqiza igagasi le-PWM nge-DSP ukuze lilawule idivayisi yamandla, bese lihlukaniswa futhi likhishwe yi-high-frequency transformer bese lilungiswa yi-high-frequency;I-LC ihlunga futhi ikhiphe amandla kagesi e-DC alawulwayo adingwa uhlelo lokuphuma kwesekethe ye-EM.
Yonke imojula yokushaja isebenza ngaphansi kokuqapha kwesistimu ye-microcomputer, okuhlanganisa ukuvikelwa kwemojula, ukulungiswa kwe-voltage, njll. Ngesikhathi esifanayo, i-microcomputer ibona ukubikwa kwedatha yokusebenza yemojula yokushaja kumojula yokuqapha futhi yamukela imiyalo yokulawula module yokuqapha.
Iphaneli Imiyalo
■ Iphaneli yokubonisa ye-LED
Ingabonisa i-module voltage, yamanje, i-alamu, ikheli, inombolo yeqembu, imodi yokusebenza nolunye ulwazi.Uma ukhiye ungasebenzi isikhathi esingaphezu komzuzu owodwa, i-voltage ne-current module izovezwa ngokuzenzakalelayo.Uma kune-alamu ngalesi sikhathi, ulwazi lwe-alamu luzovezwa.Ukunemba kwesibonisi sikagesi ngu-±0.5V, futhi ukunemba kwesibonisi samanje kungu-±0.2A.
■ Izinkomba
Kunezinkomba ezi-3 kuphaneli yemojula, okuyinkomba yamandla (eluhlaza), inkomba yokuvikela (ephuzi) kanye nenkomba yephutha (ebomvu).Bheka ithebula elingezansi.
