This paper deals with the reduction of the harmonic content of the output voltage of a single-phase multi-level cascaded inverter which is optimized using the Particle Swarm Optimization (PSO) technique. The operating parameters of the inverter are modified, such as the number of stages, the voltage at the sources and the switching pattern to achieve a minimum configuration that satisfies a Total Harmonic Distortion (THD) of less than 5% and the less possible number of power semiconductor devices.
