Harmonics elimination technique applied to an NPC topology three level inverter used as static VAr compensator

In this paper the use of harmonics elimination method applied to a three level inverter is reported. The method used to calculate the switching angles is clearly shown and discussed. Simulations results using Pspice program and experimental results are carried out to validate the mathematical model. Finally, we applied this harmonics elimination method to control an advanced static VAr compensator (ASVC) which uses a three level voltage source inverter.
