A Hybrid Modulation Technique for Operating Medium-Voltage High-Power CHB Converters Under Grid Voltage Disturbances. IEEE Transactions on Industrial Electronics, 71 (1), 462-472. https://doi.org/10.1109/TIE.2023.3241246.0278-00461557-9948https://hdl.handle.net/11441/173924Power converters, and particularly multilevel converters, are key elements in the current energy scenario. Among them, cascaded H-bridge converters are a popular and versatile solution for many industrial applications. Technical literature provides multiple modulation techniques for its operation. Among them, hybrid pulsewidth modulation techniques provide a good tradeoff between switching loss and output voltage quality. In this article, a hybrid modulation technique is presented, which allows not only the fundamental block switching operation of some power cells but also a harmonic control over a specific harmonic distortion present in the grid. To validate the operation of the proposal, several experimental results have been reported to demonstrate the good behavior of the proposed modulation technique.application/pdf10 p.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Harmonic analysismultilevel converterspulsewidth modulationinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/TIE.2023.3241246
