Distributed power generation systems may necessitate connecting multiple independent energy sources that employ various converter topologies. A recent development in this field is the emergence of impedance source converters, offering the ability to deliver buck-boost functionality within a single stage. The split-source inverter (SSI) has been introduced as a novel choice in between this family. Many control strategies have emerged for electrical power systems control. Among the recent emerging controllers, model predictive control strategies have become an effective technique for control systems. Model predictive controllers (MPCs) offer a number of features compared to the conventional and counterpart models such as enhanced system response and improved system transients with reduced steady-state error. This research suggests a finite control-set MPC for three-phase single-stage SSI supporting a standalone load for remote area applications. Considering the proposed FCS-MPC, the output load current tracks its reference magnitude with minimized error. In addition, the proposed FCS-MPC enhances the proposed SSI system performance with a settling time of 10 μs, and approximately without overshoot in the output current. The system has been validated using Opal-RT OP-4510 and the power loss model of the inverter has been explained. In the end two comparisons have been presented to clarify the main points in the topology structure and the control technique. [ABSTRACT FROM AUTHOR]

This paper introduces a study of reduced devices count symmetric multilevel inverter (MLI) under two PWM techniques for AC applications. The MLI uses two DC sources to synthesize five‐level output voltage at a reduced switching devices number. The MLI employs five switching devices comprising the main and auxiliary circuits. The main circuit is a single‐phase H‐bridge inverter, which controls the output voltage polarity. The auxiliary circuit controls the input DC bus voltage by altering the number of the input DC cells to the frontend of the main circuit. Two PWM techniques are considered to control the MLI output based on minimum power loss and reduced total harmonic distortion, which in turn, elect the inverter application. To verify the effectiveness of the proposed MLI as well as the importance of the two PWM techniques, the five‐level inverter has been carried out experimentally using a laboratory prototype. DSPACE‐DS 1103 digital controller is utilized, to implement the experimental system controller, for controlled load voltage regulation. [ABSTRACT FROM AUTHOR]
