Fractal Based Space Vector PWM for Three Level Inverter

S.Jeyaseeli

This paper presents a space vector pulse width-modulation technique based on fractal approach for multilevel inverters is presented. Here the properties of fractal structure together with the simplicity of fractal arithmetic are exploited to generate the SVPWM. The proposed method does not use any lookup tables for sector identification. The switching space vectors are also directly determined without using any lookup tables. Simulations are carried out using MATLAB/Simulink for a three level inverter. The proposed scheme can be extended to an n-level inverter, and a generalized algorithm is also presented
