Since 2008, the PCIM Europe Conference has been presenting this annual honor to young talents in the power electronics industry. The winning contributions will be presented by the successful candidates at the conference from 9.5.2023 – 11.5.2023.
Three Best Paper Awards, one Young Engineer Award and one Young Researcher Award were honored once again this year. The PCIM Europe Advisory Board, chaired by Prof. Dr. Leo Lorenz, ECPE, selected the five winners from over 400 submissions. The main criteria were the timeliness, relevance and quality of the submission.
The awards were presented by Prof. Dr. Leo Lorenz and this year's conference sponsors Semikron Danfoss, Littelfuse, Infineon, VW and Mitsubishi Electric. The winners of the awards will also receive prize money of €1,000.
The Best Paper Award honored the top three submissions overall. Engineers aged 30 or younger were eligible to apply for the Young Engineer Award. Since 2022, the Young Researcher Award has been given to an author aged 30 or under from the field of science and research institutions.
The winners of the three Best Paper Awards are:

Impact of Current Density on Wire Bond Lifetime – Power Cycle Testing with Clamped VCE for Realistic Current Stress
In power cycling tests, end-of-life failure modes of IGBT modules are provoked by repetitive DC current pulses. However, in real-life inverter operation a big portion of the power losses is due to switching events and much smaller currents are present in the module. Especially the wire bond lifetime depends on the current density and exaggerated test load currents can lead to early wire bond lift-off. This article presents experimental results on the impact of current density on wire bond lifetime and introduces a novel PC test method that allows for testing with moderate currents.

Design and Testing of a Compact Dry Insulated Medium Frequency Transformer Prototype for Medium Voltage Applications
Medium voltage solid state transformers with a modular structure require compact insulated medium frequency transformers with high efficiency to be an attractive solution. In this paper, the design, prototyping and test of a cast resin 12 kV class insulated medium frequency transformer with more than 99.5% efficiency and more than 5kW/L power density is described. Dielectric performances are demonstrated experimentally. An accurate measurement method for the losses as well as a full load test method are also presented.

Advanced Solid-State-based Protection Scheme for High-Voltage Li-ion Battery Energy Storage System
Safety issues such as external short-circuit (ESCs) increase discharge rate and hence impose impacts on Li-ion batteries by raising the temperature. To minimize these effects, high-speed protection schemes are required to eliminate ESCs.

Machine-Learning Approach to Model Junction Temperatures in Automotive Inverters
Increasing power density of automotive inverters lead to an increasing demand for accurate lifetime and reliability models. As such models are closely dependent on junction temperatures, they benefit from accurate temperature estimation methods. In this contribution, a machine-learning approach to model semiconductor junction temperatures is presented. The model was trained and evaluated with data from a test bench incorporating a 1200 V SiC power module. The data pipeline, model performance, benefits and limitations are shown and discussed.

Implementation and Characterization of a 200 kW Full-SiC Isolated DC-DC Converter for Future Medium Voltage PV Plants
Nowadays, taking into account the new projects of photovoltaic (PV) power plants, novel architectures with an intermediate medium-voltage DC (MVDC) collector are under consideration. Thus, high-power isolated DC-DC converters are key components to accelerate the deployment of these architectures. The author presents the implementation and characterization of a prototype which is a 200-kW two-stage isolated DC-DC converter based on Medium Voltage SiC Power Modules.
