Development and Installation of Multi-Level Inverter for Industrial Applications

Abstract

This article develops a new design for single phase asymmetric cascade converters and implements it using the best hardware components. This solution drastically reduces the count of DC sources and semiconductor switches, thus reducing need for door drivers. The proposed multi-level inverter generates a display form with low THD output and high stepped voltage at the output. The setting is disproportionate and generates 31 various output voltages. MATLAB is used to validate digital software modelling and has been tested experimentally on laboratory-scale prototypes. The inverter was tested under conditions of stable and dynamic load changes. The combination of numerical and experimental results provides clear evidence that meets the expectations of theoretical elaboration. The proposed converter has the application in non-conventional energy. This is a major challenge to increase the self- confidence of researchers with low THD. For basic 13-level and advanced 31-level MLI, a number of parameters were analysed, including Cost Function (CF), Total Constant Voltage (TSV) and power reduction.
