Reliability evaluation of three-level inverters
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010To date, many inverter topologies have been proposed in the literature with each exhibiting certain advantages and disadvantages. These inverters are however mostly proposed with their reliability indexes left unexplored. The main reason for a lack of reliability assessment might be a lack of existing quantitative techniques that can be used for ...

A novel three-level PV inverter
2012 7th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2012A novel three-level buck-boost type inverter is proposed in this paper. It combines the series-parallel diode-capacitor network with the traditional buck-boost converter, plus the full bridge inverter as the back stage. The new inverter can boost or lower the input voltage.

A new ZVZCS three-level inverter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017This paper presents a new ZVZCS three-level inverter with T-type structure. The proposed inverter can achieve ZCS on arm switches and ZVS on neutral point switches by series connecting the arm switches with resonant inductors and parallel connecting the neutral point switches with resonant capacitors.

Optimal pulse width modulation for three-level inverters
IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2004The three-level neutral-point-clamped voltage source inverter is widely used in high power, medium voltage applications. This paper studies continuous and discontinuous PWM for this inverter. Detailed analysis of discontinuous modulation shows that the average switching frequency is not directly proportional to the carrier or sampling frequency, since ...

Analysis and compensation of inverter nonlinearity for three-level T-type inverters
2016 IEEE Applied Power Electronics Conference and Exposition (APEC), 2016This paper analyzes the inverter nonlinearity effect resulting in issues such as narrow pulses and the even order harmonics in three-level T-type inverters. These issues make the compensation of the inverter nonlinearity be difficult. Based on the analysis of the output voltage distortion, carrier-based PWM methods to avoid these issues and to balance ...

A control scheme for three level inverter
International Symposium on Signals, Circuits and Systems, 2005. ISSCS 2005., 2006In this paper a control strategy for a three-level neutral point clamped inverter (NPC) is described on the assumption that the inverter feed an induction motor drive with vector control. In the NPC inverter, the three level pulse width modulation (PWM) techniques based on the sine triangle FWM and space vector modulation are used to drive the ...

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.

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.

Three level dual Buck half bridge inverter
2009 International Conference on Sustainable Power Generation and Supply, 2009Three level dual Buck half bridge inverter topologies, especially the coupled-inductance dual Buck inverter, are presented. Dual Buck inverter is a new configuration which has the characteristics of high frequency and efficiency. However the output of the bridge is in bi-polarity PWM waveform and the voltage stress is high.
