Kwanan nan, Shanghai Yongming Electronic Co., Ltd. ta ƙaddamar da na'urorin tallafi na DC, waɗanda ke da fa'idodi guda huɗu masu ban mamaki wanda hakan ya sa suka dace da IGBTs na ƙarni na bakwai na Infineon. Suna kuma taimakawa wajen magance ƙalubalen kwanciyar hankali, aminci, rage farashi, da farashi a tsarin SiC.
Na'urorin ɗaukar fim suna samun kusan kashi 90% na shigar da bayanai a cikin manyan aikace-aikacen faifai. Me yasa SiC da IGBT ke buƙatar su?
A cikin 'yan shekarun nan, tare da saurin haɓaka sabbin masana'antun makamashi kamar adana makamashi, caji, da motocin lantarki (EVs), buƙatar na'urorin DC-Link suna ƙaruwa da sauri. A taƙaice dai, na'urorin DC-Link suna aiki a matsayin masu hana ruwa shiga a cikin da'irori, suna shanye manyan kwararar iska daga ƙarshen bas ɗin kuma suna daidaita ƙarfin bas ɗin, don haka suna kare makullan IGBT da SiC MOSFET daga manyan kwararar iska da tasirin ƙarfin lantarki na ɗan lokaci.
Yawanci, ana amfani da ƙarfin lantarki na aluminum electrolytic capacitors a aikace-aikacen tallafi na DC. Duk da haka, tare da ƙarfin bas na sabbin motocin makamashi yana ƙaruwa daga 400V zuwa 800V kuma tsarin photovoltaic yana motsawa zuwa 1500V har ma da 2000V, buƙatar capacitors na fim yana ƙaruwa sosai.
Bayanai sun nuna cewa a shekarar 2022, ƙarfin da aka shigar na inverters na lantarki bisa ga DC-Link film capacitors ya kai raka'a miliyan 5.1117, wanda ya kai kashi 88.7% na jimillar ƙarfin da aka shigar na na'urorin sarrafa lantarki. Manyan kamfanonin sarrafa lantarki kamar Fudi Power, Tesla, Inovance Technology, Nidec, da Wiran Power duk suna amfani da DC-Link film capacitors a cikin inverters na drive ɗinsu, tare da jimlar ƙarfin da aka shigar har zuwa 82.9%. Wannan yana nuna cewa capacitors na fim sun maye gurbin electrolytic capacitors a matsayin babban abin da ke cikin kasuwar tuƙi ta lantarki.
Wannan kuwa saboda matsakaicin ƙarfin lantarki na ƙarfin lantarki na masu ƙarfin lantarki na aluminum shine kimanin 630V. A cikin manyan ƙarfin lantarki da aikace-aikacen wutar lantarki mai yawa sama da 700V, ana buƙatar haɗa masu ƙarfin lantarki da yawa a jere da layi ɗaya don biyan buƙatun amfani, wanda ke haifar da ƙarin asarar makamashi, farashin BOM, da matsalolin aminci.
Wani takarda daga Jami'ar Malaysia ta nuna cewa ana amfani da na'urorin lantarki masu ƙarfin lantarki a cikin hanyar haɗin DC na inverters na rabin-gado na silicon IGBT, amma ƙaruwar ƙarfin lantarki na iya faruwa saboda juriya mai yawa (ESR) na masu ƙarfin lantarki masu ƙarfin lantarki. Idan aka kwatanta da mafita na IGBT na silicon, SiC MOSFETs suna da mafi girman mitoci na sauyawa, wanda ke haifar da mafi girman ƙarfin lantarki a cikin hanyar haɗin DC na inverters na rabin-gado. Wannan na iya haifar da lalacewar aikin na'ura ko ma lalacewa, saboda mitar amsawar na'urorin lantarki masu ƙarfin lantarki 4kHz ne kawai, wanda bai isa ya sha ripple na yanzu na inverters na SiC MOSFET ba.
Saboda haka, a cikin aikace-aikacen DC waɗanda ke da buƙatun aminci mafi girma, kamar inverters na tuƙi na lantarki da inverters na photovoltaic, galibi ana zaɓar capacitors na fim. Idan aka kwatanta da aluminum electrolytic capacitors, fa'idodin aikinsu sun haɗa da juriyar ƙarfin lantarki mafi girma, ƙarancin ESR, babu polarity, aiki mai ƙarfi, da tsawon rai, wanda ke ba da damar ƙirƙirar tsarin da ya fi aminci tare da juriyar ripple.
