Abstract: Three-phase two-level voltage source converters are used for distribution static compensator (DSTATCOM) applications and can be replaced by a multilevel inverter. In this paper, an LCL filter interfaced cascaded H-bridge multilevel inverter-based (CHBMLI) DSTATCOM is simulated and its performance is analyzed considering the system parameters. The analysis considers factors including t...

 This paper presents multilevel inverters as an application for all-electric vehicle (EV) and hybrid-electric vehicle (HEV) motor drives. Diode-clamped inverters and cascaded H-bridge inverters, (1) can generate near-sinusoidal voltages with only fundamental frequency switching; (2) have almost no electromagnetic interference (EMI) and commonmode voltage; and (3) make an EV more accessible/saf...

In PWM inverter-fed drives, a variation of Common mode voltage (CMV) causes unbalanced voltage operation in induction motor. Multilevel inverters reduce this problem, but the complexity of the power circuit increases with an increase in the number of inverter voltage levels. In this paper, a five-level inverter is compared with two, three and four levels and this five level structure is propose...

The cascaded multilevel inverters (MLIs) are suitable topologies when a high number of voltage levels needed. Nonetheless, possess the main drawback power switches and gate drivers that make sophisticated control, reducing efficiency, increasing cost. This article proposes new fundamental switched-diode topology is capable generating five positive-voltage with only three switches, diodes, dc so...

Cascaded multilevel inverters offer several advantages over other multilevel structures: modularity, high voltage capability, reliability. Additionally, a large number of cascaded inverters using a square wave modulation method allow low losses in the inverter and low harmonic distortion in the output voltage. This paper analyzes the main features of one of these modulation methods especially i...
