PUC Optimal Switching Strategies for Renewable Applications in Single Phase Inverter

Nowadays, a lot of different sectors and researchers employ multilevel inverters for high power medium voltage applications. Because of this, hybrid topologies with fewer components have become increasingly popular. In this paper, the authors present an architecture for Hybrid Packed U-Cells that combines fewer switches with or without voltage balancing (H-PUCs). Eight switches are necessary for the proposed H-PUC for it to be able to offer voltage output at levels 7 and 15. H-PUC makes use of a combination of high voltage low frequency (HVLF) and low voltage high frequency (LVHF), which helps to reduce the amount of power that is wasted while simultaneously improving efficiency. A simulation and validation of the topology for the 7-level asymmetry is carried out on a microcontroller with the model number C2000. To evaluate the functionality of the proposed inverter, a simulation is run in the MATLAB programming environment. The H-PUC inverter topology that has been presented is one that is capable of being implemented in applications involving the integration of renewable energy.
