Voltage oriented control of three-phase PWM rectifier using space vector modulation and input output feedback linearization theory

摘要

The current energy challenges encourage the researchers to design and optimize the devices allowing the conversion and the control of energy. The power converters consist in adapting the source of energy to the needs for the load. In this paper, we present the study of voltage oriented control with space vector modulation (VOC-SVM) strategies for three-phase PWM rectifiers. This strategy of control founded on the transformation between stationary coordinates α-β and synchronous rotating coordinates d-q, it is based on the input-output feedback linearization controller for which the objective is to control the grid current's d- and q-axis component, while the dc-bus voltage is maintained at the desired level and satisfy the unity power factor (UPF) operation. The strategy VOC-SVM ensures high static performance and fast transient response by using internal current control loop. Moreover, the studies were carried out by using simulation under the environment Matlab/Simulink.
