Analyses And Simulation Of The Three-Phase Controlled Inverter Using Space Phasors And Spice Model

This paper presents the analyses and simulation of the three-phase controlled inverter with transistors that can run as three phase inverter with two devices or three devices in conduction in steady-state. The first part makes the presentation of three-phase inverter using the step matrix in normal function. The form of tension on load results by making the equivalent circuit for every period tact. Because each alternation of load tension is approximated with several levels, the inverter is called inverter with pulses. The function of inverter is analyzed by space phasors, simulated by SPICE model and performed for resistive and resistive-inductive load. The simulation is made in each case and is a comparison between the obtained waveforms is made. From this circuit analysis results that we have an inverter with several pulses (levels) or multi levels inverters.
