style="line-height:200%;">前言：整流器英語：rectifier，是指將交流電轉換為直流電的裝置，可用于供電裝置和無線電信號的檢測等。整流器由真空管、起火管、固體硅半導體二極管、汞弧等制成。在備用UPS只需充電電池，不需要負荷供電，只需充電機。在雙重變換UPS中，該裝置為變頻器供電，也為電池充電，因此被稱為整流器/充電機。<br /> <br /> 整流器的作用<br /> 整流器是整流裝置，簡而言之，將交流(AC)轉換為直流(DC)的裝置。有兩個作用功能<br /> （1）首先，把交流電(AC)變成DC(DC)，過濾后供給負載，或者供給逆變器；<br /> （2）其次，為電池提供充電電壓。因此它還起到充電器的作用；<br /> <br /> 整流器應用<br /> 整流器的主要應用是將交流電源轉換為直流電源。雖然所有的電子設備都需要使用直流，但電力公司的供電是交流，所以除非使用電池，所有的電子設備的供電器內部都需要整流器。<br /> <br /> 至于把直流電源的電壓進行轉換則復雜得多。直流-直流轉換的一種方法是首先將電源轉換為交流（使用一種稱為反用換流器的設備），然后使用變壓器改變該交流電壓，最后再整流回直流電源。<br /> <br /> 整流器還用在調幅(AM)無線電信號的檢波。信號在檢波前可能會先經增幅(把信號的振幅放大)，如果未經增幅，則必須使用非常低電壓降的二極管。使用整流器作解調時必須小心地搭配電容器和負載電阻。電容太小則高頻成分傳出過多，太大則將抑制訊號。<br /> <br /> 整流裝置也用于提供電焊時所需固定極性的電壓。這種電路的輸出電流有時需要控制，此時會以可控硅(一種晶閘管)替換橋式整流中的二極管，并以相位控制觸發的方式調整其電壓輸出。<br /> <br /> 晶閘管也用于各級鐵路機車系統中，以實現牽引馬達的微調。可關斷晶閘管(GTO)則可用于從直流電源產生交流，例如在 Eurostar 列車上使用此方式提供三相牽引馬達所需的電源。<br /> <br />
