LC滤波器感应电机驱动中的电感选择、改进型有源阻尼及无电压传感器无速度传感器运行

Owing to the phase delay and resonance oscillations introduced by the LC filter connected in-between the voltage-source inverter (VSI) and the induction motor (IM), the “L” and “C” design methodology is critical. Also, the closed-loop control and the speed sensorless operation of such drives are complex without stator voltage sensors. This article addresses these issues by proposing a simple filte...
