In several pages, I have read that it is possible to obtain a sine wave (maybe with harmonics) from a three-phase inverter, with six transistors or thyristors, like this:

3-phase inverter

I have seen some techniques, like SPWM, but I am not sure about the correct working of those techniques.

I would like to know if it's possible to obtain sine waves from such inverter.

Thank you in advance.

  • \$\begingroup\$ If switching time is fast, inductors La/b/c are large, a decent load is present, and a the controller monitors output voltage, what will be output should resemble a sine wave. Depending on the capabilities of the controller. \$\endgroup\$ – rdtsc 2 days ago
