Job Description
Introduction
Are you ready to play a pivotal role in powering accelerating systems for the worlds largest particle accelerator currently under study the Future Circular Collider (FCC) Join CERNs Electrical Power Converter Group (EPC) and leave your mark on the development and operation of the electrical systems for CERNs particle accelerators. Take part!
You will join the Accelerator Systems Department (SY) which is responsible for the beamrelated technical systems of the CERN accelerators. The SY teams design build and operate equipment systems in all CERN accelerators and are engaged in ambitious forwardlooking R&D programmes.
The Electrical Power Converter Group in the Accelerator Systems Department (SY) is responsible for the electrical power systems for the entire CERN accelerator complex.
You will join the dynamic FastPulsed Converter Section responsible for most of high voltage power converters (from 10s of kW to multiMW) at CERN.
Functions
As an Electrical Engineer you will be an integral part of a multidisciplinary R&D team actively shaping the future of accelerator technology. You will take the lead in defining and developing the power systems for a broad spectrum of Radio Frequency (RF) equipment ranging from a few kilowatts up to 130 megawatts which are critical to accelerating particle beams in nextgeneration accelerator projects currently under development.
You will:
Power Converter design and modelling
- Define optimal topologies and switching technologies for both Low Voltage (LV) and High Voltage (HV) DC/DC and AC/DC power converters including highvoltage protection devices such as solidstate switches (e.g. IGBTbased fast disconnectors). Converter power ratings range from a few tens of kilowatts to several megawatts;
- Develop analytical and numerical models to evaluate power converter performance considering parameters such as efficiency dynamic response size footprint and cost based on specific input/output requirements;
- Design and refine digital control strategies to improve converter performance and reliability;
- Validate models through simulations and when necessary smallscale prototyping.
SystemLevel optimization
- Integrate converter models into a broader systemlevel optimization framework to reduce costs and enhance overall system performance;
- Collaborate closely with specialists across various accelerator technology domains to ensure cohesive and efficient system design.
Reporting and communication
- Present project progress challenges and outcomes in internal meetings and external conferences;
- Produce comprehensive technical documentation to support R&D activities and knowledge sharing.
Qualifications :
Masters degree or PhD or equivalent relevant experience in the field of electrical engineering or power electronics or a related field.
Experience:
Required experience:
- Demonstrated experience in design and modelling of power electronics converters topologies;
- Proven experience with power semiconductors technologies thermal and electrical simulation tools such as Matlab/Simulink.
Desired experience:
- Initial experience with Python;
- Initial experience in numerical optimization.
Technical competencies:
- Design and modelling of power electronic components and systems;
- Knowledge and application of power electronics techniques;
- Functional analysis of control systems.
Behavioural competencies:
- Achieving results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
- Managing self: working well autonomously; taking on activities and tasks without prompting; taking initiative beyond regular tasks and making things happen.
- Working in teams: building and maintaining constructive and effective work relationships.
- Solving problems: addressing complex problems by breaking them down into manageable components.
- Communicating effectively: giving praise and providing honest and constructive feedback.
Language skills:
Spoken and written English with a commitment to learn French.
