●采用IGBT鉗位三電平拓?fù)浣Y(jié)構(gòu)，使零電位可控，輸出電壓波形更接近于正弦波，高次諧波分量較二電平變頻器顯著降低，對(duì)電網(wǎng)及控制系統(tǒng)的電磁干擾明顯改善。
IGBT clamping tri-level topology structure is adopted to make zero potential controllable, and the output voltage waveform is closer to sine wave. Compared with 2-level converter, the high-order harmonic component is significantly reduced, and the electromagnetic interference on the power grid and control system is significantly reduced.
●1140V三電平變頻器輸出電壓峰值較二電平變頻器降低一半，能有效的避免電機(jī)繞組絕緣擊穿的問(wèn)題。
The peak output voltage of 1140V three-level converter is only half of two-level converter, which can effectively avoid the insulation breakdown of motor windings.
●采用無(wú)傳感矢量控制技術(shù)。
The sensor - free vector control technology is adopted.
●模塊化結(jié)構(gòu)設(shè)計(jì)，維護(hù)維修更便利。
Modular structure design, more convenient maintenance.
