Abstract :
This paper discusses the optimization designing method for a 5-level ANPC inverter. The point of the mathematical expression is to observe the losses of a converter based on the study of the device condition. Selection of the capacitor is also discussed accordingly based on the design method. The performance of the 5-level ANPC inverter is compared with a conventional 2-level inverter. The validity of the proposed calculation method for the power loss is confirmed with the experimental results. The 5-level ANPC inverter can achieve higher efficiency than the 2-level inverter.
