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.

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.

PWM Three-Level Inverter Control
2006 IEEE International Conference on Automation, Quality and Testing, Robotics, 2006This paper analyses a PWM control circuit for a three-level three-phase inverter. The power circuit of inverter and the PWM control principles, using a mirror triangular waveform, are explained. The output voltages of the inverter are represented by 21 Park vectors, from which 3 vectors are null.

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

Three level rectifier versus three level inverter with DTC controlled induction motor
The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004A three level NPC-rectifier versus three level NPC-inverter with direct torque controlled asynchronous motor is examined. Three level inverters have the problem of the DC-link voltage balance, especially if DTC control is considered. To reduce the problem both DC voltage and the potential of its middle point are controlled through a three level V.S.R ...
