rudzi rutsva rwemagetsi emagetsi emagetsi-yepamusoro-frequency switching power supply. Iyo inosanganisa mabhenefiti eiyo waveform kutsvedzereka kwesilicon rectifiers uye kurerukira kwevoltage regulation yesilicon-inodzorwa rectifiers. Iyo ine yakanyanya kunaka ikozvino kushanda (kusvika 90% kana kupfuura) uye idiki vhoriyamu. Iyo inovimbisa kugadzirisa. Iyo tekinoroji yekugadzira yakagadzirisa dambudziko remagetsi, uye iyo yakakwirira-simba inoshandura magetsi kubva kuzviuru zveamps kusvika kumakumi ezviuru zveamps yakapinda muchikamu chinoshanda chekugadzira.
Inogadzirisa zvakananga uye kusefa iyo AC magetsi gidhi kuburikidza neEMI anti-electromagnetic interference line sefa, inoshandura iyo DC voltage kuita yakakwira-frequency square wave yemakumi kana mazana ekHz kuburikidza neinoshandura, inoparadzanisa uye inoderedza voltage kuburikidza nepamusoro-frequency. transformer, uye ipapo kuburikidza yakakwirira Frequency kusefa goho DC voltage. Mushure mekuita sampling, kuenzanisa, kukwidziridza uye kutonga, kutyaira dunhu, chiyero chebasa chechubhu yemagetsi mushanduri inodzorwa kuti iwane yakagadzikana yakabuda voltage (kana kubuda ikozvino).
Iyo yekugadziridza chubhu ye-high-frequency switching rectifier inoshanda munzvimbo yekuchinja, kurasikirwa kwesimba kudiki, kugona kunogona kusvika 75% kusvika 90%, vhoriyamu idiki, huremu hwakareruka, uye iko kurongeka uye ripple coefficient zviri nani. kupfuura iyo silicon rectifier, inogona kunge iri mune yakazara inobuda renji. Wana kurongeka kunodiwa nekugadzirwa. Iyo ine kuzvidzivirira kugona uye inogona kutanga nekumira zvisina tsarukano pasi pemutoro. Inogona kubatana nyore nyore nekombuta, iyo inounza kurerukirwa kukuru kune otomatiki kugadzirwa uye inoshandiswa zvakanyanya muPCB plating indasitiri.
Features
Uchishandisa nguva yekudzora basa, kurongeka kuri nyore uye kuri nyore, uye nguva yekushanda yeakanaka uye yakaipa yazvino polarity inogona kuiswa zvisina tsarukano zvinoenderana nezvinodiwa zveplating.
Iine matatu anoshanda maitirwo e otomatiki cycle commutation, yakanaka uye yakaipa, uye kudzosera kumashure, uye inogona otomatiki kushandura polarity yezvinobuda.
Kukwirira kweperiodic commutation pulse plating
1 Reverse pulse current inonatsiridza kukora kugova kwejasi, ukobvu hwejasi hwakafanana, uye kuenzana kwakanaka.
2 Iyo anode dissolution ye reverse pulse inoita kuti kusanganisirwa kwesimbi ion pane cathode pamusoro pepamusoro kusimuke nekukurumidza, izvo zvinobatsira pakushandiswa kwepamusoro pulse ikozvino density mune inotevera cathode cycle, uye yakakwirira pulse ikozvino density inoita kuti kuumbwa kwekukurumidza iyo crystal nucleus inokurumidza kupfuura chiyero chekukura kwekristaro, saka Iyo yekupfekedza ine dense uye yakajeka, ine yakaderera porosity.
3. Reverse pulse anode stripping inoderedza zvakanyanya kusungirirwa kwehutsvina hwehupenyu (kusanganisira blightener) mumucheka, saka kuvhara kune kuchena kwepamusoro uye kupikisa kwakasimba kwekushanduka kwemavara, iyo inonyanya kuzivikanwa mune sirivha cyanide plating.
4. The reverse pulse current oxidizes the hydrogen iri mujasi, iyo inogona kubvisa hydrogen embrittlement (yakadai sereverse pulse inogona kubvisa co-deposited hydrogen panguva ye electrodeposition ye palladium) kana kuderedza kushushikana kwemukati.
5. The periodic reverse pulse current inochengetedza pamusoro pechikamu chakapfava mumamiriro ekushanda nguva dzose, kuitira kuti jira rekuputira rine simba rakanaka rekubatanidza rinogona kuwanikwa.
6. Reverse pulse inobatsira kuderedza hukuru chaihwo hwekupararira uye kuvandudza cathode ikozvino kushanda. Naizvozvo, akakodzera pulse paramita anozowedzera kukurumidza dhizaini chiyero chekupfeka.
7 Muplating system isingatenderi kana zvishoma zvekuwedzera, kaviri pulse plating inogona kuwana yakanaka, yakatsetseka, uye yakatsetseka.
Nekuda kweizvozvo, zviratidziro zvekubatika senge tembiricha kuramba, kupfeka kuramba, welding, kuomarara, corrosion kuramba, conductivity, kuramba kubuda kwemavara, uye kutsvedzerera kwakawedzera exponentially, uye inogona kuchengetedza zvakanyanya isingawanzo uye yakakosha simbi (inenge 20% -50 %) uye chengetedza zvinowedzera (zvakadai seBright silver cyanide plating ingangoita 50% -80%)
