一般適用于老設(shè)備的節(jié)電改造，原來(lái)高壓電機(jī)設(shè)備的改造，高低高控制方案對(duì)于2，000KW以下高壓變頻器非常適合，此技術(shù)采用變壓器將高壓降到低壓，在購(gòu)買低壓變頻器裝置，再將變頻器輸出電壓經(jīng)過(guò)變壓器直接升到高壓驅(qū)動(dòng)高壓電機(jī)。

　　目前德國(guó)西門子公司在中國(guó)有較多的銷售實(shí)績(jī)。而且該公司出口到歐美的設(shè)備也在中國(guó)采購(gòu)輸入輸出變壓器，可見(jiàn)此方案有的性。

　　高低高控制的優(yōu)點(diǎn)是技術(shù)成熟，可靠性高，維修服務(wù)方便，投入成本低。

　　由于變頻器的廣泛應(yīng)用，中小容量的高壓電機(jī)已逐步減少需求，主要是因?yàn)樽冾l器能夠有效的控制起動(dòng)電流，運(yùn)轉(zhuǎn)效率及功率因子，因此中低容量高壓電機(jī)應(yīng)該盡量改選用低壓驅(qū)動(dòng)目前歐洲有些電機(jī)廠都已生產(chǎn)低壓電機(jī)到1，500KW，用戶可以選購(gòu)低成本，低維護(hù)費(fèi)用，率，高可靠性的變頻裝置驅(qū)動(dòng).
