A New Control Approach of a Three-Phase Inverter Two Levels

In this paper, we present the study, modelling and simulation of duty cycle modulation (DCM) based on SVPWM control technique using Matlab/Simulink software. It is one most advanced techniques space vector (SVM), which can be used for controlling static converters or electrical machines to achieve better dynamic performance. DCSVM a that generates signals two-level voltage converter as well intermediate times. The main advantage reduction number calculations, especially trigonometric functions generation reference voltage. order reduce computational effort, have designed controller able faithfully reproduce same vectors output quantities classical SVM. test functionality validity control, developed different simulations result in total harmonic distortion (THD) current 41.19% 15.19% respectively with fundamental values 61.51 V 2.80 A current; contrast SVM gives 47.27 2.01 THDs 77.16% 16.00% current. This results an improvement rate around 25.5%. obtained are very satisfactory. real competitor its various variants.
