| Abstract: | Multilevel inverters (MLIs) have been widely used to enhance photovoltaic (PV) systems' power quality. However, the efficiency of the system is significantly impacted by the requirement for a large number of components, a greater standing voltage, and a high harmonic content in the typical MLI's output. Therefore, asymmetrical MLIs have been created as a good substitute to deal with these problems. The goal of the current study is to create a hybrid asymmetrical structure with a high level per component ratio and a minimal standing voltage that is appropriate for PV applications. A reduced switch H-bridge based (RSHB) MLI structure with n asymmetrical repeating units and various level doubling circuit (LDC) combinations is used to build the suggested MLI. The suggested MLI structures, i.e., PS1 and PS2, may synthesise 4n+5 and 4n+7 levels, respectively, at the output instead of 2n+3 levels with only RSHB MLI. The two dc sources utilised in the repeating units are in the ratio of 1:n voltage ratio. According to a comparative examination, PS1 and PS2 are less expensive, have fewer switches, less standing voltage, and reduced power loss. The PS1 structure's performance is assessed using a 3.9 kW standalone solar PV system that employs both carrier-based pulse width modulation (PWM) and selective harmonic elimination (SHE) control techniques. Therefore, the LDC's self-voltage balancing mechanism and dc-link voltage balancing are justified. The suggested MLI is extensively simulated using the MATLAB/Simulink platform under various conditions, including step changes in solar insolation, abrupt load changes, frequency changes, and modulation index changes. Additionally, a prototype of the suggested seventeen-level MLI is subjected to comparable testing in order to empirically corroborate the theoretical and simulation results. |
