“…The selected converter topologies are presently among the most technologically mature. Variant A is a 3-level neutral point clamped (NPC) converter topology [8] with commonly used Si IGBT devices [9,20,21], while variant B is a 2-level topology [10] with less common SiC MOSFET devices [11,22,23] (SiC devices have been used due to the required voltage rating of the devices). Figure 7 presents single phase leg arrangements of each converter topology.…”

“…The paper demonstrates the use of the MTM on an example MEE/MEA power system, where the tool is used to evaluate two separate power converter design variants, from [7], of the generatorside active rectifier. The first variant considers 3-level converter topology [8] with Si IGBTs [9], while the second variant considers 2level converter topology [10] with SiC MOSFETs [11]. In each variant, the evaluation includes the comparison of two hardware components and four switching control algorithms in order to identify optimal design options.…”

There is a well-recognised need for robust simulation tools to support the design and evaluation of future More-Electric Engine and Aircraft (MEE/MEA) design concepts. Design options for these systems are increasingly complex, and normally include multiple power electronics converter topologies and machine drive units. In order to identify the most promising set of system configurations, a large number of technology variants need to be rapidly evaluated.This paper will describe a method of MEE/MEA system design with the use of a newly developed transient modeling, simulation and testing tool aimed at accelerating the identification process of optimal components, testing novel technologies and finding key solutions at an early development stage. The developed tool is a Matlab/Simulink library consisting of functional sub-system units, which can be rapidly integrated to build complex system architecture models. This paper will demonstrate this functionality by applying the tool to assess the suitability of various designs of active power converter circuitry for use with an example MEE/MEA network. Three aspects of the converters' performance will be considered in order to assess this suitability: efficiency, power quality and fault tolerance. The example case studies will demonstrate the adequacy of the selected variant designs as well as the system level impacts of design decisions. This will enable system designers to rapidly identify variant configurations of electrical components at early design stage that satisfy MEE/MEA system requirements.

“…Then HV, MV, and LV cell can be composed of power devices rated at 6.5 kV, 2.5 kV, and 1.2 kV in blocking voltage, respectively. The LV cells operating with PWM can increase their switching frequency or reduce their switching loss by applying up-to-date 1.2-kV SiC-JFET [14] or SiC-MOSFETs [15], [16].…”

This paper deals with a cascaded multilevel converter which has multiple dc voltage values (multi-voltage cascade converter, or hybrid multilevel converter) for a 6.6-kV transformerless distribution static synchronous compensator (D-STATCOM). A control method is proposed to realize dc voltage regulation of series-connected multiple cells in the STATCOM operation, making it possible to remove dc sources from all H-bridge cells. The simplified configuration without the dc sources makes the STATCOM small and lightweight. A downscaled STATCOM model rated at 220 V and 10 kVA is built and a series of verification tests is executed. Theoretical analysis and experimental results prove the stable operating performance of the proposed method in steady states and transient states.

“…Generally, in automobile applications, high current (>100A) power devices and high-temperature operation are needed. In [14], a 4H-SiC planer MOSFETs with high blocking voltage (1.3kV) and relatively large current (40A) have been developed for automotive applications. In addition, they have succeeded in fabricating the larger current (300A) 4H-SiC trench MOSFET with low-on resistance (2.6mΩcm 2 ).…”

Today, there is an increasing demand for high frequency, high power and high temperature applications where the converters will operate in a harsh environment. Switching devices based on Silicon Carbide (SiC) offer a significant performance improvement on the switch level compared with Si devices. This paper describes the current state of the art in SiC devices briefly. Then the research and development of applying SiC devices in military and industrial applications are given respectively. And challenges regarding broader implementation of SiC devices today are emphasized. Finally, a short outlook into the future for upcoming SiC power devices is given.
