Article Preview

Abstract:

This paper presents the implementation of a microcontroller-based Harmonic Elimination PWM (HEPWM) switching scheme of a Cascaded H-Bridge Multilevel Inverter (CHMI) for renewable energy system. This technique applies Particle Swarm Optimization (PSO) technique to allow computation of HEPWM switching angles. The detail description on the microcontroller-based implementation is provided in this paper. The performance of CHMI employing the control strategy based-on the simulation and experimental results are shown for comparison purposes.
