變(bian)頻(pin)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)是將市電(dian)(dian)(dian)(dian)中的(de)(de)(de)交流(liu)電(dian)(dian)(dian)(dian)經過AC→DC→AC變(bian)換,輸出(chu)為(wei)(wei)純凈的(de)(de)(de)正弦波(bo)，輸出(chu)頻(pin)率和電(dian)(dian)(dian)(dian)壓一定范圍內可調的(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)。它有(you)(you)別于(yu)(yu)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)機調速(su)用(yong)的(de)(de)(de)變(bian)頻(pin)調速(su)控制器(qi)，也有(you)(you)別于(yu)(yu)普通交流(liu)穩壓電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)。理想的(de)(de)(de)交流(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)(de)(de)特點是頻(pin)率穩定、電(dian)(dian)(dian)(dian)壓穩定、內阻等于(yu)(yu)零、電(dian)(dian)(dian)(dian)壓波(bo)形為(wei)(wei)純正弦波(bo)（無失(shi)真）；變(bian)頻(pin)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)十分接近于(yu)(yu)理想交流(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)，因此，先進發達國家越來越多地將變(bian)頻(pin)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)用(yong)作標準(zhun)供(gong)(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)，以便為(wei)(wei)用(yong)電(dian)(dian)(dian)(dian)器(qi)提(ti)供(gong)(gong)最(zui)優良(liang)的(de)(de)(de)供(gong)(gong)電(dian)(dian)(dian)(dian)環境，便于(yu)(yu)客觀(guan)考核(he)用(yong)電(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)技術性能。
變頻電(dian)源(yuan)是采(cai)用IGBT逆變(bian)輸(shu)出(chu)(chu)技術(shu)，用先進微處(chu)理器控(kong)制設(she)計而成的(de)高(gao)性(xing)(xing)能精密電(dian)(dian)源，它具有過(guo)流、短(duan)路、過(guo)壓(ya)、過(guo)載等保護(hu)及報警故障(zhang)顯示功能，確保用電(dian)(dian)設(she)備及變(bian)頻(pin)電(dian)(dian)源安全。具有負(fu)載適應性(xing)(xing)強，輸(shu)出(chu)(chu)波形(xing)品(pin)質(zhi)好(hao)(hao)，良好(hao)(hao)的(de)人機界面，操作簡(jian)單，體積(ji)小，重量輕等特點。純正(zheng)弦波輸(shu)出(chu)(chu)，可調輸(shu)出(chu)(chu)電(dian)(dian)壓(ya)及頻(pin)率的(de)變(bian)頻(pin)電(dian)(dian)源為用電(dian)(dian)設(she)備提供了所需要的(de)交流電(dian)(dian)。
變(bian)頻電源應用目的及領域:
由于世(shi)界(jie)各國(guo)電(dian)網指標不統(tong)一，出(chu)口電(dian)器(qi)廠(chang)商需要電(dian)源(yuan)模擬不同國(guo)家的(de)(de)電(dian)網狀況，為(wei)工程師在設(she)計開發、生(sheng)產線測(ce)(ce)試及品(pin)保的(de)(de)產品(pin)檢測(ce)(ce)、壽命、過高壓/低壓模擬測(ce)(ce)試等應用中提供純(chun)凈(jing)可靠的(de)(de)、低諧波失真、高穩(wen)定的(de)(de)頻率和(he)穩(wen)壓率的(de)(de)正弦波電(dian)力輸出(chu)；進口原裝電(dian)器(qi)、設(she)備的(de)(de)用戶也需要對我國(guo)電(dian)網進行變壓、變頻以保證進口電(dian)器(qi)、設(she)備的(de)(de)正常運轉；滿足航空(kong)電(dian)子(zi)及軍事設(she)備的(de)(de)需求。
