目前，中國小型乘用車保有量已趨近2億。而由于自動擋車型便于操作，市場保有量已達到了新高度。至2015年，自動變速箱的新車裝車率就增長到了80%，而國內(nèi)銷售的進口車，有95%以上裝配的都是自動變速箱。龐大的保有量，造就了這一市場的火熱。眾所周知，傳統(tǒng)的汽車修理廠主要是以機修、鈑噴、發(fā)動機油、輪胎為主要經(jīng)營項目，隨著競爭的愈發(fā)激烈，他們的盈利能力逐漸下降，生存空間也被嚴重擠壓。因此，越來越多的修理廠力爭去尋求可實現(xiàn)增值的服務(wù)項目。而對于一些**企業(yè)，尋找一個突破點是很容易的事情，通過一個項目以點帶動面，使企業(yè)依然生機勃勃。這時，“自動變速箱專項養(yǎng)護”等增值項目逐漸出現(xiàn)，且大有推廣之勢。但當(dāng)前國內(nèi)的一二類汽車綜合維修廠在“自動變速箱專項養(yǎng)護”方面，依然還屬于盲區(qū)。他們不是不想去拓展，其實更多的是一些擔(dān)心和一些風(fēng)險。國內(nèi)大部分汽車維修廠每天所面對的車型極其復(fù)雜，因此很難掌握每一款車型所配備的是什么形式的變速箱(AT、CVT、DCT)。即便看到變速箱也不一定能夠認識，這樣在保養(yǎng)環(huán)節(jié)中不得不求助外援來完成操作過程。 “外冷內(nèi)熱”的戶用市場：逆變器企業(yè)誰能拔得頭籌？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="并網(wǎng)微型逆變器品質(zhì)保障,微型逆變器"

三相型微型逆變器通常也為兩級式，仍需升壓環(huán)節(jié)，整體電路所需器件較多，成本較單相式逆變電路高。無升壓環(huán)節(jié)的三相拓撲雖然效率較高，但目前應(yīng)用對象為特定的大功率輸出光伏面板，并不具備普遍性。如若引入升壓環(huán)節(jié)，該類型拓撲和多級式拓撲類似，電路所需器件亦較多。由于微型逆變器多采用小容量的逆變器設(shè)計，其效率相對較低，而且成本較高。通過分析目前提出的微型逆變器結(jié)構(gòu)可知，單級式微型逆變器由于結(jié)構(gòu)簡單，所需開關(guān)數(shù)目較少，成本相對于多級式逆變器較低，且效率相對較高，若能進一步改進功率解耦電路，同時引入軟開關(guān)技術(shù)，使功率解耦電路和逆變器電路均工作在軟開關(guān)狀態(tài)，不僅能降低主電路的損耗，提高整體效率，還能減少器件的發(fā)熱，進一步提升系統(tǒng)的可靠性，高效率低成本的單級式微型逆變器將更具吸引力。另外，影響微型逆變器可靠性的因素還有很多，當(dāng)前對于提高微型逆變器工作壽命問題的研究主要集中在如何取代電路中電解電容這一方面，實際中微型逆變器的極端工作環(huán)境、封裝、制作工藝等均會影響設(shè)備的可靠性。在微型逆變器設(shè)計中應(yīng)綜合考慮多方面的因素。大功率逆變器+低電壓并網(wǎng)，實現(xiàn)工商業(yè)項目降本。**微型逆變器知識</p><p

隨著光伏電池技術(shù)的快速發(fā)展，光伏模塊成本的不斷降低以及電力電子技術(shù)的進步，分布式光伏發(fā)電系統(tǒng)相比其他可再生能源系統(tǒng)表現(xiàn)出極強的市場競爭力。光伏微型逆變器，也稱為光伏交流模塊式逆變器，因具有發(fā)電量高、安全性好、制造成本低、安裝維護方便、支持“即插即用”、系統(tǒng)容量易于擴展等優(yōu)點，在分布式光伏發(fā)電系統(tǒng)中逐漸被采用?；谔摂M直流母線結(jié)構(gòu)的反激式微型逆變器，輸入輸出隔離、結(jié)構(gòu)緊湊、控制簡單，近年來成為研究熱點。華南理工大學(xué)電力學(xué)院、深圳茂碩電氣有限公司的研究人員對相關(guān)研究成果進行分析，針對當(dāng)前研究中的不足，將一個開關(guān)管和一個二極管集成于升壓-反激變換器，構(gòu)建了一種非隔離虛擬直流母線混合微型逆變器。該電路拓撲在半工頻周期內(nèi)交替工作于升壓-反激（Boost-Flyback,BF）模式和反激（Flyback,F）模式：當(dāng)工作于BF模式時，在低的變壓器匝比和漏感量下，獲得了高的電壓增益和低的電壓應(yīng)力，此外，還提供了固有的無損吸收電路，漏感能量得以回收利用，實現(xiàn)了主開關(guān)管的電壓鉗位；F模式解決了BF模式不能降壓的問題，使得在直流母線處產(chǎn)生直流正弦全波（饅頭波）成為可能。并網(wǎng)微型逆變器品質(zhì)保障</p><p
