Abstract :
A novel model-based sensorless input current controller for three phase active rectifiers is presented. The proposed algorithm is based upon a load conductance rectifier controller, which was previously implemented using current sensors. The paper presents analytical studies, simulation results and discusses a simple implementation using a low-cost integrated microcontroller. Experimental verification utilizes a 50 kVA active input/output IGBT converter. Simulation and experimental results for the proposed controller are compared to that of the sensor based version to validate the efficacy of this novel algorithm
