Multilevel converters have been under research and development for more than three
decades and have found successful industrial application. However, this is still a technology …

Neutral-point-clamped multilevel converters are currently a suitable solution for a wide
range of applications. It is well known that the capacitor voltage balance is a major issue for …

This paper discusses the modular multilevel cascade converter (MMCC) family based on
cascade connection of multiple bidirectional chopper cells or single-phase full-bridge cells …

This paper briefly reviews the common-mode voltage (CMV) and neutral point (NP) voltage
for neutral point clamped three-level inverter (NPC TLI). Then, the space vector pulsewidth …

Four-level hybrid-clamped inverter is a newly proposed topology that can operate under a
wide voltage range without switches connected in series. However, when it is applied in …

The neutral-point voltage unbalance problem holds back the extensive application of neutral-
point-clamped (NPC) multilevel converters with more than three voltage levels in industry …

This paper proposes a simplified space vector modulation (SVM) scheme for multilevel
converters. Compared with earlier SVM methods, the proposed scheme simplifies the …

In this paper, the properties and operation of the virtual-space-vector pulse-width modulation
(PWM) for a three-level neutral-point-clamped inverter with unbalanced dc-links are studied …

Neutral-point voltage imbalance is one of the main problems of five-level neutral-point
clamped inverters that impedes their industrial application. In order to solve this problem, a …

This paper presents a fast and generalized space vector pulse width modulation (SVPWM)
scheme for any multilevel inverter. The SVPWM scheme generates all the available …
