Simulation of Three-Phase Voltage Source SPWM Inverter

摘要

Simulation model of Three-phase full bridge voltage source SPWM Inverter was set up. Typical voltage and current wave was analyzed. Fast Fourier Transform, for short FFT of phase voltage, line voltage, instantaneous phase power were given. FFT of voltage source output current thus output power was also given, adjust value of frequency and inductance, the influence was analyzed. This Simulation model was intuitive, can show waves dynamically, it's helpful in product design and development, and has important value.
