摘要
A predictive control scheme to control the phase currents of a three-phase power converter coupled to the electric grid by means of an LCL network is developed. This kind of coupling offers several advantages when compared to pure inductive coupling networks, namely a greater attenuation of switching harmonics and a smaller size. Equations that model the behavior of the current through the LCL network in terms of the applied voltages are, however, more complicated to obtain. In this paper the difference equations required to implement a discrete predictive control scheme are obtained and tested by simulations when it is operated as an inverter and as a controlled rectifier.
