機(jī)械設(shè)計(jì)與電氣設(shè)計(jì)應(yīng)相互配合。許多生產(chǎn)機(jī)械采用機(jī)電結(jié)合控制的方式來(lái)實(shí)現(xiàn)控制要求，因此要從工藝要求、制造成本、結(jié)構(gòu)復(fù)雜性、使用維護(hù)方便等方面協(xié)調(diào)處理好機(jī)械和電氣的關(guān)系。
隨著科學(xué)技術(shù)水平的不斷提高，新型大功率電力電子元器件的誕生，集成電路和微機(jī)技術(shù)的應(yīng)用，交流變頻調(diào)速技術(shù)已日趨完善和成熟。交流變頻調(diào)速系統(tǒng)以調(diào)速范圍寬、動(dòng)態(tài)響應(yīng)快、調(diào)速精度高、保護(hù)功能完善和操作簡(jiǎn)單等優(yōu)點(diǎn)，已在冶金、石化、電力、機(jī)械、民用電器等行業(yè)得到廣泛應(yīng)用。

20世紀(jì)80年代后半期開(kāi)始，美、日、德、英等發(fā)達(dá)國(guó)家的VVVF變頻器已投入市場(chǎng)并獲得了廣泛應(yīng)用。至于想了解各類變頻器工作原理的話，不妨由簡(jiǎn)至繁的看看變頻器控制方式的四種演變。
變頻器就是把工頻電源(50Hz或60Hz)變換成各種頻率的交流電源，以實(shí)現(xiàn)電機(jī)的變速運(yùn)行的設(shè)備。而這其中控制電路完成對(duì)主電路的控制，整流電路將交流電變換成直流電，直流中間電路對(duì)整流電路的輸出進(jìn)行平滑濾波，逆變電路將直流電再逆成交流電（及核心控制電路實(shí)現(xiàn)：交-直-交的過(guò)程）。
