Five-level nested inverter with neutral point connection

2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe), 2020
Multilevel inverter technology has been a well-established concept especially in medium voltage drives. This paper presents a new five-level nested inverter topology, that has a neutral point connection and two flying capacitors per phase. Compared to five-level topologies presented previously, the proposed topology has the same switch count, but fewer

Five-level reduced hybrid inverter with coupled inductors

2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017
This paper investigates two five-level reduced hybrid inverters with split-wound coupled inductor and reduced number of components. The proposed inverters are composed of two legs, one of two levels and another of three-levels. Two types of three-level leg have been investigated: diode-clamped and flying capacitor.

Harmonic elimination in a five level multilevel inverter

2016 International Conference on Computer Communication and Informatics (ICCCI), 2016
Multilevel inverters are popular for renewable energy applications. This paper presents a technique for harmonic elimination in a five level cascaded H-Bridge multilevel inverter. The technique is based on computation of switching angles using Chebyshev polynomials. The method involves simple mathematical calculations to arrive at the desired switching

A Single-Phase Five-Level Transformerless Photovoltaic Inverter

2020 IEEE Applied Power Electronics Conference and Exposition (APEC), 2020
The five-level inverters are preferred solutions for medium-voltage PV applications because of lower total harmonic distortion (THD), lower switching stress and lower electromagnetic interference in contrast to two-level inverter topologies. In order to reduce the leakage current in the five-level inverter applications, a single-phase five-level ...

Discussions of parallel-connected five-level PWM inverters

IECON'99. Conference Proceedings. 25th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.99CH37029), 2003
Multi-level PWM inverters have significant advantages such as the ability to operate the motor with nearly sinusoidal current waveforms and higher output voltages. In order to increase the inverter size, the parallel connection method would be effective for the present.

A novel five-level inverter for solar system

2014 IEEE Applied Power Electronics Conference and Exposition - APEC 2014, 2014
This paper compares the advantages and disadvantages of I-type 5-level inverter and T-type 5-level inverter, involving the conduction loss, commutation path in reactive power and switching loss, especially at high frequency. Based on the analysis, this paper proposes a novel 5-level inverter for solar system, aiming at reducing both the conduction loss
