Simulation and Experiment of Three-Phase Inverter Based on SVPWM

Abstract:

Aiming at the simulation of the three-phase inverter and SVPWM, the paper introduces their principles. A new method to build SVPWM simulation block in MATLAB/Simulink is proposed. The on-voltage-drop of the power devices is taken into account; the switch and diode are modeled as the connection in series of a resistance and a voltage source in simulation. The simulation and experiment results verify the correctness of simulation models, and show that the on-voltage-drop of the power devices has effects on the phase current and phase/line voltage, especially when the inverter works at a light load state.
