Tessenderlo (BEL) or Bevaix (CH) – 4 to 6 months

Subject: Gradiometric Hall-based current sensing

Project Description

As an intern at Melexis, you will be engineering current sensor solutions for automotive EV applications. Hall-based current sensors typically require a ferromagnetic element to increase the magnetic field and to improve the stray-field immunity. Melexis has developed a new technology that does not require this additional element. This makes it a very promising solution for the future of electric vehicles.

More specifically, you will:


        Understand the advantages and drawbacks of this new current sensing technology

        Characterize the stray-field immunity and the mechanical play robustness of this new sensor

        Optimize the bus bar dimensions to reach the best performance

        Optimize the PCB design to be robust against inductive and capacitive coupling

        Build a current sensor prototype based on your findings

        Integrate and validate your prototype in our high voltage lab in Switzerland

Expected results

        Develop a clear understanding of the gradiometric Hall-based current sensors

        Validate the simulations done during the development of the product with measurements

        Build a prototype that is showing the optimal results

        Provide a set of guidelines that are justified by measurements on a real inverter



        Self-motivated student, eager to learn, curious and enterprising with strong problem-solving mindset

        Strong experience with electrical measurements and characterization in a lab environment

        (Strong) experience with hall sensors and/or magnetic circuits

        Experience with Python is a plus

        Experience with Altium or any PCB design tool is a plus



Melexis Current sensing branch has increased significantly in the past few years, closing projects with major OEMs such as Tesla (X/S/3/Y), Renault (Zoé, E-TECH) or BYD. Supported by the growing electrification of vehicles, Melexis is expanding its current sensing branch: upon excellent work and strong motivation, this Master Thesis or Internship will lead to a permanent position offer.


Joining Melexis for your internship is the opportunity to build up your know-how in a high-tech, international and dynamic company, benefit from the experience and training of our experts and enjoy the welcoming and friendly atmosphere of our teams. The Bevaix office is specialized in Hall Sensors and Wireless technology and counts 70 employees. The Tessenderlo office is the headquarter.
