Abstract

This paper proposes a Space Vector PWM (SVPWM) algorithm based on fractals for two legged three phase multilevel inverters. The paper presents the observation that the space vector representation of two legged three phase multilevel inverter has an inherent fractal structure. The properties of fractal structure together with the simplicity of fractal arithmetic are utilized to propose a generalized algorithm for SVPWM generation for two legged multilevel inverters and it can be easily extended to n-level inverters. The voltage space vectors of higher level inverter can be generated from the voltage vectors of an equivalent 2-level inverter using simple addition operations. Sector identification and switching vector determination in SVPWM generation are carried out using simple arithmetic operations without any computational complexity. The proposed algorithm doesn’t use any look up table for sector identification and switching vector determination. The validation of the algorithm through simulations in MATLAB/SIMULINK has been carried out for two legged 3-level and 5-level inverter configurations for which the results are also presented.
