An overview of three-phase voltage source active rectifiers interfacing the utility

In this paper an overview of the three-phase voltage source active rectifiers and their applications is given. The basic control methods like phase and current controls are described. Advanced control such as two-axis based, feedforward and active damping if an LCL-filter is used are also described. The use of emerging control technologies such as direct power control, fuzzy control and soft computing like genetic algorithm are investigated. Particular attention is also paid to industrial problems such as cost, reduction of the number of sensors, non- ideal conditions, such as grid unbalance, LCL-filter design and EMI-issues. Finally, some tests results are presented and discussed in order to provide the theoretical analysis with a solid experimental basis.
