uhlobo olusha lwe-electroplating power supply equipment-high-frequency switching power supply. Ihlanganisa izinzuzo zokushelela kwe-waveform ye-silicon rectifiers kanye nokuba lula kokulawulwa kwamandla kagesi kwezilungisi ezilawulwa yi-silicon. Isebenza kahle kakhulu njengamanje (kufika ku-90% noma ngaphezulu) kanye nevolumu encane kakhulu. Ingumlungisi othembisayo. Ubuchwepheshe bokukhiqiza buyixazulule inkinga yamandla, futhi ukunikezwa kwamandla okushintshwa kwamandla aphezulu kusuka ezinkulungwaneni zama-amps kuya emashumini ezinkulungwane zama-amps kungene esigabeni esisebenzayo sokukhiqiza.
Ilungisa ngokuqondile futhi ihlunge igridi yamandla e-AC ngesihlungi somugqa we-EMI anti-electromagnetic interference, iguqule i-voltage ye-DC ibe igagasi lesikwele le-high-frequency yamashumi noma amakhulu e-kHz ngesiguquli, ihlukanise futhi yehlise i-voltage nge-high-frequency. i-transformer, bese ngokusebenzisa i-high Frequency filtering output DC voltage. Ngemuva kwesampula, ukuqhathanisa, ukukhulisa nokulawula, isifunda sokushayela, isilinganiso somsebenzi weshubhu yamandla kusiguquli silawulwa ukuze kutholwe i-voltage ephumayo ezinzile (noma yamanje okukhiphayo).
Ishubhu yokulungisa ye-high-frequency switching rectifier isebenza esimweni sokushintsha, ukulahleka kwamandla kuncane, ukusebenza kahle kungafinyelela ku-75% kuya ku-90%, ivolumu incane, isisindo silula, futhi ukunemba kanye ne-ripple coefficient kungcono. kunesilungisi se-silicon, esingaba kububanzi obuphelele bokuphumayo. Thola ukunemba okudingekayo ngokukhiqiza. Inekhono lokuzivikela futhi ingaqala futhi ime ngokuzenzakalelayo ngaphansi komthwalo. Ingaxhunywa kalula nekhompiyutha, okuletha ukunethezeka okukhulu ekukhiqizeni okuzenzakalelayo futhi isetshenziswa kabanzi embonini ye-PCB yokucwenga.
Izici
Ngokusebenzisa umsebenzi wokulawula isikhathi, ukulungiselelwa kulula futhi kulula, futhi isikhathi sokusebenza se-polarity yamanje enhle nesibi singasethwa ngokungafanele ngokuvumelana nezidingo zenqubo yokucwenga.
Inezimo ezintathu zokusebenza zokushintshwa komjikelezo okuzenzakalelayo, okuhle nokubi, kanye nokuhlehla, futhi ingashintsha ngokuzenzakalelayo i-polarity yokuphumayo kwamanje.
Ukuphakama kwe-periodic commutation pulse plating
1 I-Reverse pulse current ithuthukisa ukusatshalaliswa kogqinsi kwento enamathelayo, ukujiya kwento enamathelayo kuyafana, futhi ukulevelina kuhle.
2 Ukuqedwa kwe-anode kwe-reverse pulse kwenza ukuhlangana kwama-ion ensimbi endaweni ye-cathode kukhuphuke ngokushesha, okuvumela ukusetshenziswa kwe-high pulse yamanje ukuminyana kumjikelezo we-cathode olandelayo, futhi ukuminyana okuphezulu kwe-pulse kwamanje kwenza isivinini sokwakheka i-crystal nucleus ngokushesha kunezinga lokukhula kwekristalu, ngakho-ke I-coating iminyene futhi ikhanya, ine-porosity ephansi.
3. I-reverse pulse anode stripping kunciphisa kakhulu ukunamathela kokungcola okuphilayo (okuhlanganisa i-brightener) ekugqokeni, ngakho-ke ukugqoka kunokuhlanzeka okuphezulu kanye nokumelana okuqinile nokushintsha umbala, okugqame kakhulu ekufakweni kwesiliva kwe-cyanide.
4. I-Reverse pulse current i-oxidize i-hydrogen equkethwe ku-coating, engaqeda i-hydrogen embrittlement (njengokungathi i-reverse pulse ingasusa i-hydrogen e-co-deposited ngesikhathi se-electrodeposition ye-palladium) noma inciphise ukucindezeleka kwangaphakathi.
5. I-periodic reverse pulse current igcina ingaphezulu lengxenye epuletiwe isesimweni esisebenzayo ngaso sonke isikhathi, ukuze kutholakale ungqimba lokucwenga olunamandla okubopha okuhle.
6. I-Reverse pulse iyasiza ukunciphisa ukushuba kwangempela kwesendlalelo sokusabalalisa futhi ithuthukise ukusebenza kahle kwamanje kwe-cathode. Ngakho-ke, imingcele efanele ye-pulse izoqhubekisela phambili ukusheshisa izinga lokubekwa kwe-coating.
7 Ohlelweni lokucwenga olungakuvumeli noma inani elincane lezithasiselo, i-pulse plating ephindwe kabili ingathola ukunamathela okuhle, okubushelelezi, nokushelelayo.
Ngenxa yalokho, izinkomba zokusebenza ze-coating ezifana nokumelana nokushisa, ukumelana nokugqoka, ukushisela, ukuqina, ukumelana nokugqwala, ukuguquguquka, ukumelana nokuguquguquka, nokushelela kuye kwanda kakhulu, futhi kungasindisa kakhulu izinsimbi ezingavamile neziyigugu (cishe 20% -50). %) bese ulondoloza izithasiselo (ezifana ne-Bright silver cyanide plating cishe ngo-50% -80%)
