Current Control of Three-Phase PWM Rectifiers without Phase Current Sensors
상전류 센서없는 3상 PWM 정류기의 전류제어
Abstract
This paper proposes a novel current control method of three-phase PWM rectifiers without phase current sensors. The features of this method are to reconstruct phase currents by using switching pattern of space vector modulation and to estimate phase currents by a predictive state observer for practical applications. Simulation results show that the performance of the proposed system is nearly the same as that of sensor-based system.
