about 15-20 invited speakers from academia and industry, sometimes complemented by a panel discussion. The majority of participants comes from industry especially from the ECPE Member companies but also the ECPE Competence Centres use these events to discuss results from their latest research with industry experts. The number of participants varies from 50 to 150 depending on the topic, the workshop locations are spread over Europe. The details regarding topics, dates and locations are available in the ECPE Calendar of Events on our web site.

10

2.2 ECPE TUTORIALS

While the Workshops are mainly focussing on expert discussion, the ECPE Tutorials are addressing education and training with the target group of young engineers in industry. The number of participants is normally limited to 35 persons to keep the classroom atmosphere. A typical ECPE Tutorial is a two-day event involving a team of 2-4 course instructors. The portfolio of ECPE Tutorials is covering the basic topics and disciplines of power electronics: power semiconductor technologies and devices, power electronics packaging, parasitics & EMC, reliability and thermal engineering. An ECPE certificate is given to those participants who attended all five basic tutorials.

2.3 INFORMATION ON EUROPEAN RESEARCH & DEVELOPMENT PROJECTS

There are several programmes and initiatives on the European R&D stage funding research projects related to power electronics. Apart from the European Commission with its framework programme Horizon 2020 and the European EUREKA initiative with the CATRENE and EURIPIDES clusters there are Joint Undertakings (JU) and Joint Technology Initiatives (JTI) working as public-private partnership e.g. ENIAC, ARTEMIS, ECSEL, FUEL CELL & HYDROGEN and CLEAN SKY. From the hundreds of research projects on European level ECPE is selecting those projects with relevance to power electronics and presenting compact project information on the ECPE web site with the project title, abstract, consortium, project volume and duration together with a link to the project web site, if available. The aim of this project overview is to provide a higher level of transparency on what is going on in power electronics research on the European level. Unfortunately, none of these programmes and initiatives is directly addressing power electronics e.g. in the headline. CATRENE: EURIPIDES: ENIAC: ARTEMIS: ECSEL:

2.4 RECRUITMENT EVENTS AND ECPE JOB FORUM

European PhD School The European PhD School on ´Power Electronics, Electrical Machines, Energy Control and Power Systems´ was founded in 1999 with the goal of providing PhD students with the opportunity to broaden their knowledge. About 100 PhD students from all over Europe take part every year. ECPE is responsible for organising the Industry Day with companies exhibition for recruitment.

ECPE Job Forum In the Job Forum on the ECPE web site network members have the possibility to search for young power electronics engineers Europe-wide. In addition, there is a separate rubric for student positions at the ECPE Member companies e.g. for practical trainings, master thesis or working students. This network service is free of charge.

ECPE PROJECTS AND INITIATIVES

3.1 ECPE ROADMAP PROGRAMME Research and Technology Roadmaps are an important strategic tool to identify and guide a mainstream for medium to long term research. The ´Power Electronics 2025´ Roadmaps will be the key element of the ECPE Strategic Research Agenda. The roadmaps are used by the ECPE Network members for different purposes: t Provide input and industrial guidance to research programmes on European as well as on national level t ECPE Member companies will reflect their own company roadmap vs. the ECPE roadmaps t ECPE Competence Centre will use the roadmaps when they define new research directions Based on the experiences from the 1st ECPE Roadmap Programme (20072010) the Roadmap 2.0 Programme is structured in three application-related groups: 1. Power Supplies (low power) 2. Automotive & Aircraft (medium power) 3. Electronic Power Grid (high power) In these three groups also technologyrelated trends e.g. wide bandgap power semiconductors and advanced integration technologies are discussed but against the background of the specific system and application field.

The 1st decade of the ECPE Network (2003 - 2013) was affected by the energy-related megatrends of energy efficiency, renewable energies and e-mobility. At that time ECPE has started a strategic process to communicate the role and importance of power electronics by stressing the user´s value and benefit as well as the societal impact. The potential of power electronics for energy saving and improvement of energy efficiency has been worked-out as well as the key role of power electronics in using

3.4 THE ECPE JOINT RESEARCH PROGRAMME The Joint Research Programme is organised within the ECPE GmbH where the Member companies who decided to join the ECPE Research Partner Agreement as Principal or Associate Partner are driving R&D projects as contract research with the Competence Centres. This Joint Research Programme is 100% industry-financed and about 10-15 projects are started every year by the ECPE Principal Partners. The research topics are proposed by the companies or, alternatively, are arising from an annual call-for-proposals published among the ECPE Competence Centres.

One exemplary highlight from ECPE Research: Ultra-low inductance package for SiC This ECPE Project realised at Fraunhofer IZM aims at the development of an advanced power package with extremely low DC-link inductance. The 1st demonstrator is a half bridge with two paralleled SiC-JFETs applying printed

Current rail inverters are mainly designed for a high voltage of 1500V from overhead wires and therefore downsizing of high voltage power modules is important. Hitachi has developed a compact 3.3kV/1200A hybrid module for rail car inverters having a high voltage resistance of 3.3kV using SiC. The hybrid module developed combines 3.3kV SiC-SBDs (Schottky barrier diode) and Si-IGBTs. To achieve a compact size module, Hitachi optimized both the SiC-SBD structure and the Si-IGBT device characteristics taking full advantage of device, cir-

They have been developed for several vehicles, such as buses, diesel-electric locomotives or light motorcycles. Other new developments have recently been presented, as the example of a low aging, easy to recycle, hybrid energy storage device based on compressed air. These activities represent one aspect of a tendency to realize so-called multidisciplinary studies, as it is often needed in the sector of energy.
