Award winners of PCIM Europe Conference 2019 announced

May 7, 2019

The Best Paper and three Young Engineer Award winners were honored during the opening ceremony of the PCIM Europe Conference 2019.

The PCIM Europe advisory board, led by Prof. Dr. Leo Lorenz, ECPE, Germany, chose this year’s winning entries from the over 370 papers submitted.

The winner of the PCIM Europe Best Paper Award is:

Jürgen Schuderer, ABB Corporate Research, Switzerland
High-Power SiC and Si Module Platform for Automotive Traction Inverter

The winners of the PCIM Europe Young Engineer Award are:

Mohamed Ahmed, Virginia Polytechnic Institute and State University, USA
GaN Based High-Density Unregulated 48 V to x V LLC Converters with ≥ 98% Efficiency for Future Data Centers

Christoph Marczok, Fraunhofer Institute IZM, Germany
Low Inductive SiC Mold Module with Direct Cooling

Miguel Vivert, Pontificia Universidad Javeriana, Colombia
Decentralized Controller for the Cell-Voltage Balancing of a Multilevel Flying Cap Converter

The Young Engineer Awards were granted to exceptional contributions from young professionals (not older than 35 years). Whereas the Best Paper Award was presented to the best paper overall. Additionally, each Award is endowed with prize money amounting to 1,000 EUR.

With the annually granted PCIM Awards, PCIM Europe has honored outstanding contributions for over ten years, also supporting young talents in the power electronics industry. In addition, supplementary travel grants were awarded to help international power electronics students attend PCIM Europe 2019. The grants were provided by the event organizer Mesago Messe Frankfurt to selected authors who will present an accepted paper at PCIM Europe Conference 2019.

PCIM Europe 2019 Best Paper Abstract:

High-Power SiC and Si Module Platform for Automotive Traction Inverter
Jürgen Schuderer, Chunlei Liu, Niko Pavlicek, Giovanni Antonio Salvatore, Jean-Yves Loisy, Daniele Torresin, Thomas Gradinger, Fabian Mohn, Arne Schröder, David Baumann, ABB Corporate Research, CH; Andreas Apelsmeier, Audi, D

A novel power semiconductor module platform for the automotive powertrain is presented in this paper. Mold modules in half-bridge configuration are designed for symmetric and minimized parasitics and all interconnects are solder-free to provide superior reliability. SiC or Si devices are packaged for the same external outline offering a simple scalability for inverter classes in the 150 – 300 kW power range. A compact screw-less and O ring-less 3-phase module is provided by a bond process of the mold modules to a low-cost Al cooler.

GaN Based High-Density Unregulated 48 V to x V LLC Converters with ≥ 98% Efficiency for Future Data Centers
Mohamed Ahmed, Virginia Polytechnic Institute and State University, USA; Fred Lee, Qiang Li, CPES, USA; Michael de Rooij, David Reusch, Efficient Power Conversion (EPC), USA

In this work an eGaN® an unregulated LLC converter with integrated magnetics is proposed for two-stage 48V Votage regulator module, the converters designed with fixed transformation ratios of 4:1 and 8:1 provide a continuous power of 900W with maximum efficiencies of 98.4% and 98.0% in high-power-densities of 94 KW/liter (1500W/in3) and 75 KW/liter(1200 W/in3) respectively. The intermediate bus voltage variation is evaluated to maximize the overall efficiency of the two-stage 48V VRM.

Low Inductive SiC Mold Module with Direct Cooling
Christoph Marczok, Eckart Hoene, Tina Thomas, Fraunhofer Institute IZM, D; Andreas Meyer, Karsten Schmidt, Rogers Germany, D

To make use of the superior properties of Wide Band Gap (WBG) semiconductors power modules are needed with optimum thermal performance, good parasitic electromagnetic properties, a high temperature capability and the possibility for a high degree of integration. In this investigation, a new setup for power modules with SiC power MOSFETs is demonstrated using multilayer ceramic substrates with direct substrate water cooling and transfer molding with a metallized and structured copper layer on top.

Decentralized Controller for the Cell-Voltage Balancing of a Multilevel Flying Cap Converter
Miguel Vivert, Pontificia Universidad Javeriana, CO; Marc Cousineau, Philippe Ladoux, University of Toulouse, F; Joseph Fabre, LAPLACE laboratory, F

This paper presents a decentralized control for a Flying-Cap converter. It is based on a balancing-voltage local controllers (LCs) and a classical output current controller (OCC). LCs cancels the difference between their local cell-voltages (CV) with the average value of the neighbouring CVs. A great deal of cells can be handled with this control. It provides also an auto-balancing if the number of cell changes. This technique decouples the dynamics between CVs and output current. Simulations and experimental results validate the theory.
