AB - AbstractThis paper presents an approach using Pigeon Inspired Optimization (PIO) for selective harmonic elimination in a cascaded H-bridge (CHB) multilevel inverter fed with unequal dc sources. The aim of this work is to find the optimal combination of switching angles, such that the lower order harmonics are eliminated and the output voltage is constant irrespective of voltage change in the input side. This paper the PIO has been used to find the optimal angles for a 7-level inverter and the method can be scaled to any number of levels. To show the effectiveness of PIO the results have been compared with other evolutionary algorithms such as genetic algorithm (GA), particle swarm optimization (PSO). An adaptive switching angle strategy has also been developed using ANN to make the proposed strategy suitable to the real-time applications. In order to verify the results, an experimental prototype of 7 level CHB has been developed in the laboratory using dSPACE ds1104 R&D controller board. The results show that the PIO is the most accurate and fastest evolutionary algorithm for switching angle optimization and the experimental results are in close agreement with the simulation results.
