Abstract
In this paper, a real time implementation of selective harmonic elimination pulse width modulation (SHEPWM) using a new technique known as Linearization Method for single phase Matrix converter (SPMC) is designed and discussed. SHEPWM for SPMC is designed using Real coded genetic algorithm (RGA), particle swarm optimization (PSO) and firefly algorithm (FFA). From the switching angle trajectory of these techniques, the trajectory of LM is designed. In the proposed technique, the optimum switching angles are obtained using simple mathematical calculations. A MATLAB simulation was carried out and FFT analysis of the simulated output voltage waveform confirms the effectiveness of the proposed method. An experimental setup was also developed and the switching angles and firing pulses are generated using Field Programmable Gate Array processor. The proposed method proves that it is much applicable in the industrial applications by virtue of its suitability in real time applications.
