The typical consumer or user of a single-phase grid-connected inverter is a small business or institution that requires a power range of less than 10 kW. Different kinds of single-phase inverters that can connect to the grid have been studied. With its high switching frequency, the three-level inverter can meet requirements, but at the expense of possibly higher switching losses, noise, and interference. The inverter's switching function generates electromagnetic interference (EMI), which can be mitigated by optimising the waveform it produces. For photovoltaic systems that link to the grid, this research presents a novel pulse width modulated (PWM) control strategy for a single-phase, seven-level inverter. The PWM signals were generated by comparing three identical reference signals with an offset equal to the amplitude of the triangle carrier signal. From the dc source voltage, the inverter may generate seven different levels of output-voltage levels (Vdc, 2Vdc/3, Vdc/3, 0, Vdc/3, 2Vdc/3, Vdc). Multilevel inverters have cleaner output waveforms and reduced THD than single-stage inverters. Extensive MATLAB simulations were run to examine the proposed multilevel inverter's operation. The inverter's output voltage can be varied by setting the modulation index to the desired value. A comparison is made between the output of a 7-level inverter and that of an 11-level inverter.
