Rennes, Ille-et-Vilaine, France Mitsubishi Electric R&D Centre Europe - France Temps plein

Context and description:

MITSUBISHI ELECTRIC is one of the leading manufacturers of power electronics related products from components such as semiconductor power devices to systems such as HVDC systems. As MITSUBISHI ELECTRIC Group’s subsidiary, MITSUBISHI ELECTRIC R&D CENTRE EUROPE includes a research division specialised in Power Electronics, in particular in the field of Heterogeneous Integration Techniques[1] and high efficiency-ultra compact converters. To further improve the power density of conversion units, activities related to magnetic components[2] and based on PCB technology are carried out.


The research division, located in Rennes (France – Britany [35]), is looking for a researcher specialized in Power Electronics, specifically Magnetic components with the following duties:

  • Make a survey of magnetic coupling techniques applicable to interleaved converters using Planar PCB inductors. Pros and cons regarding losses, volume and cost will be investigated.
  • Based on two set of specifications for converters, select the best-in-class solutions with the motivation being to further improve the power density while fulfilling thermal constraints
  • Generate the design routines under Matlab environment, potentially coupled to a FEA software (such as FEMM4.2) if co-simulations are required.
  • Practical implementation of the designed devices (PCB routing, manufacturing follow-up and mechanical assembly)
  • Small-signal characterization prior to functional validation on MERCE’s existing experimental platforms
  • Other activities related to magnetic components developed at MERCE with PCB technologies will complement this mission
  • Research results will be publishable in international conferences and journals



Expected education and experience:

  • Holding a Master Degree within the field of Power Electronics, you have spent at least 3 or 4 years of experience through a public or private R&D laboratory. A PhD graduation would be appreciated.
  • Expertise in the design of magnetic components for Power Electronics (Transformers and inductors) in conjunction with soft magnetic material technologies (ferrite, iron powders, amorphous…). Specific know-how in Integrated Magnetics (Inter-Cell Transformer, Transformer with Integrated Inductances, Coupled chokes as examples) would be a plus.
  • A good knowledge in FEA software (FEA, Maxwell2/3D) is required
  • Practical experience in converter design including the selection and the practical implementation of active/passive components but also cooling systems. Basic knowledge in routing of electronic boards would be a plus.
  • Familiar with laboratory environment and associated equipments (power supplies, scopes, thermal or electrical measuring devices or probes), knowledge in metrology and experimental measurements



Personal profile:

  • Ability to work across multiple tasks methodically and efficiently and meet committed schedules
  • Motivated to work in dynamic environment and adaptable to changes in priority
  • Excellent communication and interpersonal skills: ability of sharing information with team players (must show evidence of team-working)
  • Fluent English
  • Availability for frequent international business trips.



Contract : 12 to 18 months fixed term contract
