A Proposed Five-level Neutral Point Clamped Inverter [PDF]
ERJ. Engineering Research Journal, 2021 This paper presents a proposed five-level inverter based on conventional five-level Neutral Point Clamped (NPC) topology which is a type of Multilevel Inverters (MLIs). MLI is a great solution for high power application in addition to medium power, low power and renewable energy applications. The proposed topology reduces the number of input DC sources

A five-level inverter based on differential structure
IEICE Electronics Express, 2023 Due to the advantages of low harmonic, low pollution to the power grid, and easy filtering, multilevel inverters have attracted more attention in recent years. In this paper, a five-level inverter based on the differential structure is proposed. It doesn’t need an additional bridge arm to change the polarity of the output voltage, but synthesize the ...
