PhD Student – Circuit Breakers for Renewable Energy Integration (m/f/d)

Your mission

• Conduct literature reviews and technical analysis on medium-voltage circuit breakers (MV-CBs), focusing on renewable energy integration (e.g., solid-state/hybrid CB topologies, fault current limiting, and protection strategies)

• Design and perform experiments to validate the performance of next-gen CBs (solid-state/hybrid), including drive unit optimization, dynamic response testing, and failure diagnostics

• Perform multiphysics simulations (COMSOL, Siemens Simcenter) and CFD analysis to evaluate electro-thermal-mechanical behavior of CB geometries and optimize designs

• Develop and test experimental circuits (e.g., gate drivers, snubber circuits, sensor interfaces) and functional modules in a lab environment

• Publish research findings in high-impact journals and present at international conferences

• Generate patents and technical reports to protect innovations and support commercialization

• Maintain lab safety protocols, equipment logs, and calibration records in compliance with EHS standards

• Collaborate with cross-functional teams (power electronics, materials, controls) for system-level validation and integration

Your areas of expertise

• Master of Science (MSc) or equivalent degree in electrical engineering, power electronics, physics or related field

• Hands‑on experience with PCB assembly (soldering, wiring) and basic lab equipment (multimeter, oscilloscope, current/voltage sensors)

• Experience in working with current interruption experiments in MV/HV levels is preferred

• Experience with discreet and modular power electronics components (e.g. MOSFET/IGBT device, gate driver) is desirable

• Good working knowledge of one or more of the following software tools is advantageous: Python, PLECS, Modelica

• Flexibility to learn new things and work in highly dynamic atmosphere

• Excellent communication skills in English language; knowledge of German is an advantage
