PSIM APPLICATION TO SIMULATE AND INVESTIGATE 3-PHASE INVERTER CIRCUIT

Abstract

As alternative energy sources become more popular, the need to connect existing energy sources and grids will increase. Three-phase inverters are often used to convert DC power generated by alternative energy sources into AC power compatible with the load system[1]. The purpose of this paper is to use Psim software - a powerful tool in power electronic circuit simulation to simulate a three-phase inverter circuit with two control methods: pulse width modulation (SPWM) and 6-step control, thereby better understanding each method and their advantages and disadvantages.
