Estudo e implementação da estratégia de modulação por largura de pulsos space vector aplicada em inversores monofásico e trifásico

Abstract

This work is a space vector pulse width modulation approach, applied to a full bridge single-phase voltage source inverter and to a three-wire three-phase voltage source inverter, as well as their projects and the experimental implementation of modulations. Two sequences from space vector modulation are implemented and compared to the conventional modulation. Besides the experimental data, simulations are shown. The space vector modulation allows better CC link utilization; improve the harmonic performance and reduction of switching losses. As case study, a permanent magnet motor is connected as load to the single-phase inverter and a wound rotor induction machine to the three-phase inverter.
