Abstract :
In this paper an implementation of improved voltage oriented control for AC-DC converter has been presented and investigated. Algorithm is based on independent control of positive and negative current sequences. It contains different blocks responsible for grid synchronization, mitigation of 100 Hz component, current control and sequence extraction. Different line voltage feedforwards have been implemented and discussed according to harmonic components and operation of current controllers.
