All-Digital No-speed-sensor Vector Control Current-inverter Control System
-
摘要: 提出了基于無速度傳感器矢量控制的電流型變頻調速系統,并介紹了負載開路時,晶閘管保護的方法,電動機側并聯LC諧波濾波器的作用.Abstract: Deal with no-speed-sensor vector control current-inverter control, and the way of protect SCR when load ciruit open. The results showed that AC motor is filtered by LC filter.
