Current Controllers for single-phase Grid-connected inverters: Review and Analysis

Abstract | This paper mainly focuses on multiple current controller methods for a grid-connected inverter-based distributed generation. PI, PR, DQ, and Hysteresis controllers are the different control methods used for the analysis. Switching pulses for the conventional H-bridge inverter are generated, and the output total harmonic distortion analysis is performed using these controllers. Disadvantages of a PI current control include its steady-state errors as well as its extremely low rejection capability. As a solution to the issues of PI controller, PR controller was invented. In addition to the PI and PR controllers, Direct-Quadrature and hysteresis controllers are also studied and compared in terms of total harmonic distortion. Analytical results of the hysteresis current controller are compared with different bandwidths. The performance of these controllers has been examined using MATLAB/Simulink by evaluating the switching frequency and current THD of the inverter. |
