變頻器容量選定過程,實際上是一個變頻器與電機的佳匹配過程,常見、也較的是使變頻器的容量大於或等於電機的額定功率,但實際匹配中要考慮電機的實際功率與額定功率相差多少,通常都是設備所選能力偏大,而實際需要的能力小,因此按電機的實際功率選擇變頻器是合理的,避免選用的變頻器過大,使投資增大。對於輕負載類,變頻器電流一般應按1.1N(N為電動機額定電流)來選擇,或按廠家在產品中標明的與變頻器的輸出功率額定值相配套的大電機功率來選擇

工業電源的工作流程是怎樣的?
答:當市電進入電源後,先經過扼流線圈和電容濾波去除高頻雜波和幹擾信號,然後經過整流和濾波得到高壓直流電。接著通過開關電路把直流電轉為高頻脈動直流電,再送高頻開關變壓器降壓。然後濾除高頻交流部分,這樣後輸出供電腦使用相對純凈的低壓直流電。
