This paper presents a multi-objective Model Predictive Control (MPC) for a grid connected 2-cell 5-level quasi Z-Source (qZS) Cascaded H-Bridge (CHB) inverter. The main contribution of the proposed control approach is the design of a multi-constraint cost function to achieve multi-objective MPC strategy dealing with the complex nature of the presented qZS-CHB topology. The designed cost function takes...
Modular multilevel converter (MMC) is an attractive topology for transformer-less high voltage applications due to its capability to reach high voltage levels by the use of power semiconductors. Each submodule can be considered as a controlled voltage source where capacitor's voltage should be maintained at a certain level for proper operation of the MMC and for fault detection and protection purposes...
In this paper, a finite control set Model Predictive Control (MPC) for grid-tie quasi-Z-Source (qZS) based multilevel inverter is proposed. The proposed Power Conditioning System (PCS) consists of a single-phase 2-cell Cascaded H-Bridge (CHB) inverter where each module is fed by a qZS network. The aim of the proposed control technique is to achieve grid-tie current injection, low Total Harmonic Distortion...
This paper presents a Model Predictive Control (MPC) for grid-tied Packed U Cells (PUC) multilevel inverter. The system under study consists of a single-phase 3-cell PUC inverter connected to the grid through filtering inductor. The proposed topology allows the generation of 7-level output voltage with reduction of passive and active components compared to the conventional multilevel inverters. The...
