What is a five-level inverter based on NPC and switched-capacitor technology?

Abstract: A novel five-level inverter based on neutral point clamped (NPC) and switched-capacitor technology is proposed in this article. The proposed inverter uses six unidirectional switches, two bidirectional switches, and three capacitors. The inverter has voltage-boosting capability, allowing it to increase the voltage by a gain factor of 1.5.

What is a three-phase inverter?

At higher power levels, three-phase inverters are used, which include three single-phase stages with output voltages synchronized at 120 degrees apart. This application note describes in detail the EVAL_4KVA_230VAC_5LINV multilevel inverter designed to produce a single-phase line frequency sinusoidal output for connection to standard loads.

What is a 7-level active neutral point clamped-based SC inverter?

This article proposes a seven-level active neutral point clamped-based SC inverter with a boosting of 1.5. The proposed topology, which includes six switches, and six diodes, produces a seven-level output voltage with an efficiency of 98.4%, and voltage and current THD% of 22.27% and 10.67%.

How efficient is a five-level active neutral point clamped flying capacitor inverter?

(%) (%) The five-level active neutral point clamped flying capacitor inverter design presented here demonstrates excellent efficiency over the load range, exceeding 98.7 percent from 500 W to 4000 W and peaking at 99.1 percent at 2000 W.
