Real-time remaining life estimation (Eindhoven)

Category:                            Internship jobs
Education level:                  MSc Electrical Engineering

Context
Prodrive technologies is a developer and manufacturer of world-class electronics. It comprises over 900 employees and is one of the fastest growing companies in Europe. Our organization is based on two groups: Development and Operations. The Development department is oriented at developing first-rate electronic, mechanic and software solutions. The operations department is responsible for production, assembly, testing and life-cycle-management of electronic products and systems in the range of 1 to more than a million pieces per year.

Prodrive Technologies has developed a series of gradient amplifiers that can be used to build 3 axis gradient systems for MRI scanners. The gradient amplifier generates the current through the gradient coils and therefore consists of 3 amplifier modules that share a common power supply. In order to have fast and large enough variation in the field, high voltage and high current is required (e.g. 2100V, 1150A for NG2200). Accuracy, reliability and lifetime are very important for gradient amplifier. The latest MRI scan technologies require longer and higher current that might compromise the IGBTs life expectancy.

Assignment
Prodrive Technologies wants to acquire accurate lifetime data while MRI scans are being made. You, as a student, establish an algorithm that can be implemented in the Gradient Amplifiers to real-time keep track of the remaining useful life of the IGBTs. The calculations can be based on values that are available in the amplifier, such as: current, duty cycle, etc.  You will assess the accuracy of the algorithm by performing (destructive) tests. The algorithm is implemented in an FPGA (in VHDL code). Prodrive Technologies provides test facilities for this project and the gradient amplifier development team is available for support and reviews. The focus of the assignment may be adjusted to one or all of these topics:

  • Power electronics and IGBT physics
  • Algorithm design
  • FPGA design
  • Lifetime testing

Deliverables

  • Mathematical model of IGBT life
  • Algorithm to assess life consumption based on available parameters in the amplifier
  • Lifetime tests that proof correctness of the algorithm
  • VHDL code to implement the algorithm in an FPGA

Organization
There are only few companies in the world of technology which stand out. Prodrive Technologies is one of them. Our company was founded in 1993 by technical professionals from the Eindhoven University of Technology. Since then every year has shown a steep growth rate due to a very successful business concept in a relatively young organization (average age 28 years). Currently the total Prodrive Technologies organization consists of 900 highly skilled employees (770 FTE), who are motivated, focused and result oriented of which more than 400 engineers work in development.
