- <p>In Modular Multilevel Converters (MMC), circulating<br>currents consist of both DC and AC components. However,<br>these currents are significantly affected by even harmonic distortions,<br>which introduce ripples in the Sub-Module (SM) capacitor<br>voltages. These ripples contribute to the circulating currents,<br>increasing the voltage stress on the SM switches and adversely<br>impacting overall system performance. This paper presents a systematic<br>approach to mitigating circulating currents by employing<br>an Extended Order Generalized Integrator (EOGI), which effectively<br>removes even harmonic components from the converter’s<br>legs. The proposed solution has been evaluated against existing<br>methods and demonstrated to offer enhanced robustness in the<br>face of parameter uncertainties and sudden load variations. The<br>scheme was initially validated using MATLAB/Simulink, with<br>further real-time performance verification conducted via OPALRT<br>simulation and experiments, yielding promising results</p>
