Introduction

Join CERN’s Electrical Power Converter Group (EPC) and contribute to powering the world’s largest particle accelerator, the Future Circular Collider (FCC). Be part of the Accelerator Systems Department (SY), responsible for beam-related technical systems across CERN's accelerators, and engage in cutting-edge R&D projects.

The Electrical Power Converter Group manages the electrical power systems for CERN's accelerator complex, with the Fast-Pulsed Converter Section focusing on high-voltage power converters ranging from tens of kilowatts to multi-megawatts.

Functions

As an Electrical Engineer, you will be integral to a multidisciplinary R&D team, shaping future accelerator technology. Your responsibilities include defining and developing power systems for RF equipment, with power ratings from a few kilowatts to 130 megawatts.

You will:

1. Define optimal topologies and switching technologies for LV and HV DC/DC and AC/DC power converters, including high-voltage protection devices like solid-state switches (e.g., IGBT-based fast disconnectors). Converter ratings range from a few tens of kilowatts to several megawatts.
2. Develop analytical and numerical models to evaluate converter performance, considering efficiency, dynamic response, size, footprint, and cost based on specific input/output requirements.
3. Design and refine digital control strategies to enhance performance and reliability.
4. Validate models through simulations and small-scale prototypes when necessary.

System-Level Optimization

1. Integrate converter models into a broader system-level framework to reduce costs and improve overall performance.
2. Collaborate with specialists across various domains to ensure cohesive system design.

Reporting and Communication

1. Present project progress and outcomes in meetings and conferences.
2. Produce technical documentation to support R&D activities.

Qualifications

Master's degree or PhD in electrical engineering, power electronics, or related fields, or equivalent experience.

Experience:

• Design and modeling of power electronics converter topologies.
• Experience with power semiconductors, thermal and electrical simulations (e.g., Matlab/Simulink).

Desired Skills:

• Experience with Python and numerical optimization.
• Design and modeling of power electronic components.
• Knowledge of power electronics techniques and control systems.

Additional skills include structured work approach, autonomy, teamwork, problem-solving, and effective communication. Proficiency in English and willingness to learn French are required.
