變頻器是運動控制系統(tǒng)中的功率變換器。當(dāng)今的運動控制系統(tǒng)包含多種學(xué)科的技術(shù)領(lǐng)域，總的發(fā)展趨勢是：驅(qū)動的交流化，功率變換器的高頻化，控制的數(shù)字化、智能化和網(wǎng)絡(luò)化。因此，變頻器作為系統(tǒng)的重要功率變換部件，提供可控的高性能變壓變頻的交流電源而得到迅猛發(fā)展。
隨著新型電力電子器件和高性能微處理器的應(yīng)用以及控制技術(shù)的發(fā)展，變頻器的性能價格比越來越高，體積越來越小，而廠家仍然在不斷地進(jìn)步可靠性實現(xiàn)變頻器的進(jìn)一步小型輕量化、高性能化和多功能化以及無公害化而做著新的努力。變頻器性能的優(yōu)劣，一要看其輸出交流電壓的諧波對電機的影響；二要看對電網(wǎng)的諧波污染和輸進(jìn)功率因數(shù)；三要看本身的能量損耗如何。這里僅以量大面廣的交—直—交變頻器為例，闡述它的發(fā)展趨勢：
主電路功率開關(guān)元件的自關(guān)斷化、模塊化、集成化、智能化；開關(guān)頻率不斷進(jìn)步，開關(guān)損耗進(jìn)一步降低。
變頻器主電路的拓?fù)浣Y(jié)構(gòu)方面。變頻器的網(wǎng)側(cè)變流器對低壓小容量的裝置常采用6脈沖變流器，而對中壓大容量的裝置采用多重化12脈沖以上的變流器。負(fù)載側(cè)變流器對低壓小容量裝置常采用兩電平的橋式逆變器，而對中壓大容量的裝置采用多電平逆變器。對于四象限運行的轉(zhuǎn)動，為實現(xiàn)變頻器再生能量向電網(wǎng)回饋和節(jié)省能量，網(wǎng)側(cè)變流器應(yīng)為可逆變流器，同時出現(xiàn)了功率可雙向活動的雙PWM變頻器，對網(wǎng)側(cè)變流器加以適當(dāng)控制可使輸進(jìn)電流接近正弦波，減少對電網(wǎng)的公害。
脈寬調(diào)制變壓變頻器的控制方法可以采用正弦波脈寬調(diào)制控制、消除次數(shù)諧波的PWM控制、電流跟蹤控制、電壓空間矢量控制(磁鏈跟蹤控制)。
