Asymmetrical PWM Technique for a Three-Level Hybrid Inverter
2007 IEEE Industry Applications Annual Meeting, 2007Although the three-level neutral point clamped inverter is the most widely used multilevel topology, it still has some drawbacks mostly related to the balancing of the DC-link voltages across the capacitors and the unequal semiconductor stress. Many solutions devised in order to alleviate these problems rely on special symmetrical PWM modulation ...

SVM algorithm of three-level NPC inverter
2008 3rd IEEE Conference on Industrial Electronics and Applications, 2008On the basis of presenting the principles of space vector modulation (svm) of three-level neutral point clamped (NPC) inverter, an approach to implementation of SVM is proposed. The dwell times of vectors are calculated according to the volt-second balancing. A triangle is adopted to compare with three switching points.

A soft-switching interleaved three-level inverter
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010In this paper, a soft-switching interleaved circuit applied in three-level inverters is proposed. An interleaved three-level inverter is realized by employing two interleaved power switches in parallel at the most upper and the lowest location in traditional three-level inverters.

IGBT modules optimized for three level inverters
2010 IEEE Energy Conversion Congress and Exposition, 2010This paper will present optimized IGBT module packaging for three level inverters. Modules with nominal ratings ranging from 25A to 600A will be proposed. Total losses for a three level inverter using these new modules will be compared to the losses of a conventional two level inverter using newly developed computer simulation tools.

Analysis and implementation of a three-level PWM rectifier/inverter
IEEE Transactions on Aerospace and Electronic Systems, 2000A three-level pulse width modulation (PWM) technique for ac/dc/ac converter is proposed. Single-phase three-level rectifier based on double boost configuration with power factor correction is used in the input side. Three-phase three-level voltage source inverter based on diode clamped scheme is employed in order to reduce the harmonic content of the ...

Design of a three-level inverter for an electric vehicle.
1999A conventional two-level BIT inverter was installed in an electric vehicle to control two AC induction motors at the University of Canterbury. Nowadays, power device technology has made tremendous progress, and the IGBT becomes the best device in high-quality drive system with inverters in the mid power range.
