I-Aluminium Solar Inverter PCB Solutions for Power Systems

Isingeniso

Ama-Solar inverters asebenza njengebhuloho elibalulekile phakathi kwe-photovoltaic arrays namagridi kagesi, aguqula amandla aqondile abe amandla ashintshayo asebenzisekayo. Inselele eyinhloko ilele ekulawuleni ukuminyana kwamandla okuphezulu ngaphansi kokusebenza okuqhubekayo, ikakhulukazi ekufakweni kwangaphandle lapho amazinga okushisa e-ambient angadlula ku-70°C.

I -PCB ye-solar inverter kumele iphathe imithwalo yamandla aphezulu ngasikhathi sinye, isuse ukushisa okukhulu, futhi igcine ubuqotho bukagesi phakathi nezinkulungwane zamahora okusebenza. I-Aluminium PCB inikeza indlela yokushisa ethembekile yokuphathwa kwamandla kanye nokuqina kokusebenza kahle, ibhekana nemikhawulo eyisisekelo yezinto zebhodi lesifunda lendabuko.

Ukuqonda I-Solar Inverter PCB Architecture

Izingxenye Eziyinhloko kanye Nezinselele Zokushisa

Ama-solar inverter anamuhla aqukethe amamojula okuguqulwa kwamandla, amasekethe okulawula, izigaba zomshayeli wesango, kanye nezakhiwo zokuphatha ukushisa ezihlanganisiwe. I-PCB yesigaba samandla inesibopho esibaluleke kakhulu, isekela izindlela zamandla aphezulu ngenkathi ivumela ukulawula okunembile kokushintshana ngama-IGBT noma ama-MOSFET asebenza kumaza aphakathi kuka-10 no-50 kHz.

Ama-substrates e-FR4 endabuko ayazabalaza kulezi zinhlelo zokusebenza ngenxa yokungaphatheki kahle kokushisa kuka-0.3 kuya ku-0.4 W/m·K, okudala izindawo ezishisayo zendawo eduze kwama-semiconductors amandla. Ukungafani kwe-coefficient yokwanda okushisayo phakathi kwe-copper traces kanye ne-FR4 laminate kubangela ukucindezeleka komshini phakathi nokuhamba ngebhayisikili eshisayo, okuholela ekukhathaleni kwamalunga e-solder nokwehluleka ngaphambi kwesikhathi.

Izidingo Zokuminyana kwamandla

Imiklamo ye-PCB ye-Solar inverter idinga ukucatshangelwa ngokucophelela kwazo zombili izizinda zikagesi nezishisayo. Imikhondo yamandla kumele iphathe imisinga engaphezu kwama-ampere angu-50 kuyilapho igcina ukuhlukaniswa kwe-voltage phakathi kokufakwayo kwe-high-voltage DC kanye nokuphumayo kwe-AC. Ama-inverter ezintambo kanye nama-inverter amaphakathi afinyelela ukuminyana kwamandla asondela kuma-watts angu-5 kuya kwayi-10 ngesentimitha-skwele ngayinye, okudinga ubuchwepheshe obuthuthukisiwe be-substrate ngaphezu kwamabhodi ezendlalelo eziningi ezivamile.

Kungani i-Aluminium PCB yezicelo ze-Solar Inverter

Ukusebenza Okuphezulu Okushisayo

I -PCB ye-aluminium yezinhlelo zokusebenza ze-solar inverter ishintsha ngokuyisisekelo amandla okuphathwa kokushisa ngokwakhiwa kwe-core yayo yensimbi. Isendlalelo sesisekelo se-aluminium, ngokuvamile esiwugqinsi oluyi-1.0 kuya ku-3.0 millimeters, sifinyelela ekuqhutshweni kokushisa okuphakathi kuka-120 no-200 W/m·K—okumele ukuthuthukiswa okuphindwe ka-400 kune-FR4 ejwayelekile. Isendlalelo sokufakwa kwe-dielectric sigcina ukuhlukaniswa kukagesi ngenkathi sivumela ukugeleza kokushisa okusebenzayo kuqonde ngqo ebusweni bebhodi.

Izinzuzo eziyinhloko ze-thermal zihlanganisa:

Ukudlulisa ukushisa okusebenzayo kudinga izindlela ezishisayo eziqondile ukusuka kumaphedi engxenye kuya kusisekelo se-aluminium. Imithetho yedizayini kufanele inciphise okokusebenza kwe-dielectric ngaphansi kwezinyathelo zedivayisi yamandla aphezulu, kusetshenziswa i-thermal vias noma amabhondi aqondise ekhopha kuya ku-aluminium lapho kunokwenzeka khona. Ukuncishiswa okukhethiwe kongqimba lwe-dielectric ngaphansi kwezingxenye ezibalulekile kunganciphisa ukumelana nokushisa kwendawo ngamaphesenti angama-30 kuya kwangu-50.

Izidingo Zokuhlukaniswa Kagesi

Ukusebenza kwamandla aphezulu kudinga ukunakwa okujulile ebangeni lokucwila kanye nokususwa . Izimpawu zamandla ezithwala i-VDC engu-600 kuya ku-1000 zidinga isikhala esincane samamilimitha angu-4 kuya ku-6 kusuka kuma-cores e-aluminium asekelwe phansi, okubalwa izinga lokungcola kanye nezici zokuphakama ngokwezindinganiso ze-IEC. Izinqubo zokuhlola ziqinisekisa ukumelana kokuhlukaniswa okungaphezu kwama-megohms ayi-100 kanye nobuqotho be-hipot obuphindwe kabili kune-voltage yokusebenza kanye nama-volts ayi-1000.

Ukuthembeka Okushisayo ku-Solar Inverter PCB Systems

Ukusebenza Kwenkundla Nobude Obude

Ukwakhiwa kwe-substrate ye-aluminium kuthinta ngqo isikhathi esimaphakathi phakathi kokwehluleka ezinhlelweni ze-inverter ezisetshenzisiwe. Ngokugcina amazinga okushisa e-junction engaphansi kwemingcele ebalulekile, amabhodi ensimbi-core anciphisa amazinga okuwohloka kwe-semiconductor futhi andise isikhathi sokusebenza. Lokhu kuthembeka kuhumusha ukusebenza kahle kwe-inverter okuhlala isikhathi eside ngaphezu kwamaphesenti angama-97 ngaphansi kokusebenza okuqhubekayo ekushiseni okumaphakathi okungu-70°C.

Idatha yokusebenza kwenkundla evela ekufakweni kwesikali sosizo iqinisekisa lezi zinzuzo. Amapulazi elanga asebenza ezindaweni eziwugwadule anamazinga okushisa asemini angaphezu kuka-50°C abika ukuwohloka okuncane kokusebenza kahle lapho kusetshenziswa ubuchwepheshe obunamandla be-PCB e-aluminium. Ukuphatha okushisayo okuphakeme kuvimbela ukubuyisela ukusebenza kahle phakathi namahora okukhiqiza amandla aphezulu, okwandisa amandla okuvuna lapho ukukhanya kwelanga kufinyelela umkhawulo wawo wansuku zonke.

Ukuhlola Nokuqinisekisa

Amandla okuhamba ngebhayisikili athuthuka kakhulu ngamamojula asekelwe ku-aluminium abonisa ukusebenza okuzinzile ngokuhlolwa okushisayo okunwetshiwe. Izikhathi zokunakekela zinwebeka ngokufanele, njengoba izingxenye ezigcizelelwe ngokushisa bhá zibonisa amazinga okuhluleka aphansi kanye nokuncipha kokuwohloka ngokuhamba kwesikhathi emibuthanweni yokukhiqiza ye-solar inverter PCB.
