Engineering Physics Annotation << Back THE NEUTRAL VOLTAGE FORMING METHOD IN A THREE-PHASE FOUR-WIRE VOLTAGE INVERTER A.B. DAR’ENKOV, I.E. BERDNIKOV, A.P. SLUZOV, A.E. KHRAMOV The paper is devoted to research of three-phase four-wire inverter control method developed by the authors, which allows to correct the form of phase voltage supplied to the load using the most frequently used PWM methods (SVPWM, DPWM0-3). A description of the method (in the form of a block diagram of a three-phase four-wire inverter control system) and the results of research by means of a simulation model are presented. Simulation modeling has been performed with the developed Simulink model of the three-phase four-wire inverter and its control system. The simulation results showed that the application of the method provides a sinusoidal form of voltage when any PWM method is used. Thus, the simulation results showed that the average THDU reduction was 16,94 % and the average THDI reduction was 19,21 %. Keywords: voltage inverter, space vector pulse width modulation, four leg inverter, neutral point modulation, total harmonic distortion. DOI: 10.25791/infizik.8.2023.1347 Pp. 09-19.
