Abstract

The matrix converter is an attractive topology of power converter for the Aerospace Industry where factors such as the absence of electrolytic capacitors, the potentiality of increasing power density, reducing size and weight and good input power quality are fundamental. The matrix converter potential advantages offers the possibility to achieve the aim of the More Electric Aircraft research which intends to gradually re- place, from the aircraft architecture, the hydraulic power source and its infrastructure with electric power generation and a more flexible power distribution system. The purpose of this work is to investigate the design and implementation of a 40kVA matrix converter for an Electro Mechanical Actuator (EMA) drive system. A SABER simulation analysis of the candidate matrix converter drive systems, for this application, is provided. The design and implementation of the matrix converter is described, with particular attention to the strict requirements of the given aerospace application. Finally, the matrix converter PMSM drive system and the EMA drive system are respectively assembled, tested and commissioned.

Abstract

This paper proposes a novel control strategy for matrix converters which is coined “Direct Predictive Current-error Vector Control”. The proposed control method retains the advantageous features of both a modulation scheme and of a predictive based controller. The result is a controller that is capable of good dynamic performance and steady state response with fixed switching frequency operation. Control of load and input currents of a direct matrix converter using the proposed method is demonstrated in this paper by simulation and experimental results.

Abstract

The International Technology Roadmap for Wide-Bandgap Power Semiconductors (ITRW) has four distinct technical working groups, each providing its own perspective on the technology and industrial drivers for the adoption of wide-bandgap (WBG) power semiconductors in power electronics. This article summarizes the progress toward an initial roadmap for the packaging and integration working group of the ITRW.

14. Next generation integrated drive: a novel thermal and electrical integration technique for high power density converters used in automotive drive systems

Author

Ahmadi, Behzad, Espina, Jordi, De Lillo, Liliana, Abebe, Robert, Empringham, Lee, and Johnson, Christopher Mark

Abstract

In this paper, an innovative method of electro-thermal integration of a drive system is presented. Important challenges of this integration consist of, firstly coupled thermal design of switching power modules and PM electric motor and secondly integration of high frequency switching devices into the motor housing, without compromising the performance of these transistors. To provide a solution to these challenges, an integrated liquid cooling system for both stator windings and transistor modules is designed. On the other hand, a specific module is designed to meet the specific requirements of this packaging technique.

49. Experimental Efficiency Comparison Between a Direct Matrix Converter and an Indirect Matrix Converter Using Both Si IGBTs and SiC <sc>mosfet</sc>s.

Abstract

This paper presents an experimental efficiency comparison study between two different direct ac–ac converter topologies; a direct matrix converter and an indirect matrix converter. The evaluation is performed under variable load conditions using both discrete silicon isolated gate bipolar transistor and silicon carbide MOSFETs working at power levels up to 9 kW. Each loss measurement is carried out using two power analyzers; one placed at the input and one at the output of the converter under study. To facilitate this measurement, an output filter was necessary in addition to the normal input filter. Both converters are modulated using the same traditional symmetrical space vector approach and feature an identical input/output filter design. [ABSTRACT FROM PUBLISHER]
