Control of Standalone Cascaded H-Bridge Eleven-level Inverter Based on Twisting Sliding Mode Algorithm

This paper presents the modeling and control of the single-phase eleven-level cascaded H-bridge multilevel inverter equipped with an output LC filter. Multi-level cascaded H-bridge (CHB) inverters are commonly utilized in high power applications with medium voltage levels. To attain this purpose, a Twisting Sliding Mode controller (TSMC) is designed to regulate the output voltage according to its reference. The main concern of this study is based on the delivery of sinusoidal voltage waveforms with almost negligible total harmonic distortion (TIED). The outcomes of the simulation show that the proposed controller is successful in achieving its goals and show how effective and reliable the selected control strategy is. Simulation is carried out using MATLAB / SIMULINK.
