The voltage source inverter (VSI) is a commonly used power inverter. It converts a DC voltage into a three-phase AC voltage. So a three-phase inverter is required.
The standard three-phase inverter modulation scheme. The input dc is usually obtained from a single-phase or three phase utility power supply through a diode-bridge rectifier and LC or C filter. The inverter has eight switch states given in Table 4.1. As explained violating the KVL. Thus the nature of the two switches in the same leg is
The output voltages of a three-phase inverter have the shape of a square wave, not a pure sinusoidal wave, so they include many harmonics.
For the six switches of a three-phase inverter, there are only eight possible switch combinations, i.e., eight different switching states.
