Given the recently available IGBT switch modules up to 6.5 kV, 1200 A rating, the prospect of the diode-free variant topology of the three-level neutral-point-clamped (3-level T-type, NPC) inverter in certain medium-voltage applications is bright due to its small part count and low conduction losses compared to the diode-clamped NPC inverter.

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 control of three level PWM inverters
Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics, 1997An harmonic loss-minimized optimal PWM strategy for three-level inverters is investigated. The different PWM methods for low-, middle-, and high-speed regions are presented. It is shown that, for three-level inverters, the optimized strategy in all speed regions differs from the optimal PWM strategy of two-level inverters. The developed optimal control

PESC `92 Record. 23rd Annual IEEE Power Electronics Specialists Conference, 2003
To extend the application of insulated gate bipolar transistor (IGBT) inverters in motor drives to higher voltages, a three-level IGBT inverter has been developed. The power circuit realized and a pulse pattern generator with space voltage modulation are described. A method to control the middle point potential is suggested.

Compensation of Switch Faults in a Three-Level Inverter
2008 IEEE Industry Applications Society Annual Meeting, 2008This paper deals with open switch faults in a three-level inverter feeding a three-phase induction motor. It also investigates the fault compensation via topologies that are able to maintain the system operation for a period of time. With the proposed techniques it is possible to detect and identify the power switch in which the fault has occurred ...

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 ...

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 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 ...
