摘要
本文介绍NCHVVF系列高压变频器在某研究院声学风洞项目上的应用。该高压变频器采用电压源型单元级联的拓扑结构,具有低电压穿越、抗电网波动能力强、输入输出谐波低、转速精度高、转矩响应快、抗干扰能力强、运行可靠等特点。
This article introduces NC HVVF series medium voltage VFD application on wind tunnel. NC HVVF adopt voltage source cell cascade topology, with function of LVRT (low voltage ride through), strong resistance to power grid fluctuations, low input and output current harmonics, high control accuracy of speed and torque, strong immunity to interference and high reliability.
