Z-SOURCE INVERTER BASED ON CONSTANT MAXIMUM BOOST OPTIMIZED WITH PARTICLE SWARM OPTIMIZATION (PSO) ALGORITHM

In this paper, a new approach based on the particle swarm optimization (PSO) algorithm is proposed to tune the parameters of the Constant Maximum Boost control method for the Z-Source Inverter (ZSI). The purpose of utilizing PSO technique is to minimize Total Harmonic Duration (THD) output voltage of ZSI. The design problem of the Constant Maximum Boost control method is converted to an optimization problem with the time-domain-based objective function which is solved by a PSO technique which has a strong ability to find the most optimistic result. The Matlab/Simulink was used to verify the effectiveness of proposed control method. The simulations results prove that the Constant Maximum Boost optimized PSO algorithm has excellent ability in minimize THD output voltage toward Constant Maximum Boost.
