“…On the other hand, the IGBT module has multi-material interface that is sensitive to thermal cycling. Therefore IGCT has higher thermal cycling capability than the IGBT [9]. ETO uses GTO as the main switch, which also uses the press pack technology hence it has similar thermal cycling capability as that of the IGCT.…”

The emitter turn-off thyristor (ETO) is a new emerging high power semiconductor switch which combines the advantages of thyristor's high voltage/current capability and MOS easy gate control. Due to very high silicon utilization and use of conventional thyristor technology, it has much lower cost compared with other competing technologies. Furthermore, it has significantly improved performance in current conduction, turn-off speed, and snubberless turn-off current capability. Future ETO switches under development will also pack with additional features that no-competing technologies offer, including built-in voltage, current and temperature sensing capability, control-power self-generation capability and high-voltage current saturation capability. These capabilities make ETO a very promising power semiconductor device to reduce the cost of converter-based transmission controllers while improving the controller output power, dynamic performance, and operating reliability.

In symmetric multilevel inverters, there is a tradeoff between the output quality and the reliability and efficiency of the converter. New asymmetric and hybrid solutions, using different voltages and devices in various parts of the inverter, promise significant improvements for medium-voltage industrial drives. This paper investigates such a hybrid asymmetric nine-level inverter. It consists of a three-phase three-level integrated gate-commutated thyristor inverter (main inverter), with a two-level insulated-gate bipolar transistor H-bridge (subinverter) in series with each phase. To keep the power part simple and the efficiency high, the subinverters have no feeding from the net and can only supply reactive power. This is a very interesting solution in terms of power quality, efficiency, reliability, and cost. But the nonsupplied intermediate-circuit capacitors form an unstable system. This paper proposes a control method to stabilize their voltages. Power balancing is guaranteed by varying the common-mode voltage, using an online nonlinear model-predictive controller. The controller predicts the system evolution as a function of the control inputs. A cost function of system and control quantities is iteratively minimized in real time, to find the optimal control to apply to the system. Simulations and measurements demonstrate stable behavior in steady state and during transients. Precharging of the nonsupplied capacitors is also an issue to consider. This paper proposes a startup method that charges them in parallel with the supplied ones, without any additional equipment. Measurements show its successful application in the proposed drive system.

The three-level (3L) neutral-point-clamped (NPC) voltage-source (VSC) converter has been the standard solution in medium-voltage range for industrial applications. Recently, the NPC converter structure was improved by adding two extra active switches per phase leg, thus overcoming one of its main drawbacks: the unequal power loss among the power semiconductors. The resulting structure became known as active NPC (ANPC) converter. The high availability of these power converters is mandatory, since their maintenance or replacement imply equipment downtimes incompatible with the requirements of the production processes. The faulttolerant operation of such converters has been addressed in the technical literature, but the main proposed solutions result in more complexity and higher parts count. This work proposes a new fault-tolerant structure for the ANPC IGBT-based converter, using standard devices, with very low additional cost and small complexity. The main goal is to show that the ANPC converter can overcome different and successive failures in its power devices without loss of functionality, before its definitive downtime.
