Simple digital current control strategy for single-phase grid-connected converters
This study proposes a simple digital current control technique for single-phase grid-connected voltage source converters. Unlike conventional strategies, the proposed method does not require any proportional-integral or ...
Investigation of the possibility of removing the grid side inductance from the LLCL filter circuit
It has been shown in the literature that in the grid connected converters, which uses trap based filters, like LLCL, the grid side inductance and therefore the filter size is effectively reduced. This paper with the goal of further reducing...
Application of the Min-Projection and the Model Predictive Strategies for Current Control of Three-Phase Grid-Connected Converters: a Comparative Study
This paper provides a detailed comparative study concerning the performance of min-projection strategy (MPS) and model predictive control (MPC) systems to control the three-phase grid connected converters. To do so, first, the converter is modeled...
