Passivity-Based Control of Single-Phase Cascaded H-Bridge Grid-Connected Photovoltaic Inverter
IEEE transactions on industrial electronics (1982. Print), 2023This article presents a nonlinear passivity-based control for a grid-connected cascaded H-bridge (CHB) photovoltaic (PV) system. The proposed control system is based on a port-controlled Hamiltonian model extracted from the synchronous reference frame ...

Cascaded H-bridges for sub-module PV microinverter
2016 IEEE 25th International Symposium on Industrial Electronics (ISIE), 2016In the recent years growing interest has been given to photovoltaic (PV) microinverters. Sub-modular optimization of PV panels where the junction-box of the panel is removed and each sub-modules is connected to an individual DC-DC converter realizing independent MPPT is one promising solution especially for systems subject to partial shading.

A controller for cascaded h-bridge multilevel inverter
2016 IEEE 7th Power India International Conference (PIICON), 2016The multilevel inverter technology has gained a tremendous significance in the research area. This paper proposed a new controller for generating the switching sequence of power devices used in multilevel inverter to produce the desired output. An embedded code has been developed to control the switching states of different IGBT switches.
