Abstract
This paper proposes a 19-level inverter structure with a gain of nine times. The proposed structure consists of thirteen power switches, two diodes, and four capacitors. The proposed structure includes redundant switching states (RSS) to charge the total capacitors of the proposed structure at different levels. This paper proposes a hybrid pulse width modulation method that enables the use of redundant switching states to complete the maximum continuous discharge period (LDP) of the capacitors in a shorter time. This factor reduces the voltage ripple, minimizes the inrush current, and increases the efficiency of the inverter. Also, the proposed structure does not require a capacitor with a high rated voltage. The circuit description of the proposed 19-level structure, the conduction states of the elements during the generation of different levels, the proposed hybrid modulation method, the determination of the capacitor capacitance, and the analysis of the circuit current stress are presented. Also, a comparison between the proposed inverter and similar inverters is made, and the results indicate the superiority of the proposed structure. To investigate the performance of the circuit, a simulation of the proposed structure has been performed in MATLAB Simulink, and its results have been analyzed. Finally, the results of the implementation of a laboratory sample of the proposed structure have been presented.
