Abstract

In recent years there has been an increased demand for integration of renewable energy into the electricity grid. This has amplified research into power converter solutions required to integrate renewable technology into the electricity supply. One such converter is a H-Bridge Converter.

This paper reports particle swarm optimization (PSO) technique and Newton Raphson method for selective harmonic elimination (SHE) in pulse width modulated inverter. To minimize the THD of the output voltage of PWM inverter A PSO optimization technique and NR method is proposed to find best switching angles. This method is applied for the unipolar switching in single phase inverter for five switching angles. The switching angles are calculated to completely eliminate the lower order harmonics. The result of the unipolar case using five switching angles are compared with that of a recently reported work, based on PSO technique, And is observed that the proposed method is effective in eliminating the lower order harmonics specially 3^rd, 5^th,7^th,9^th order harmonics and THD is reducing to a greater extent than the previously reported work.
