Professional Doctorate in Engineering at Eindhoven University of Technology in RF Wireless Power Transfer

Are you ready for a two year training program while at the same time receiving a salary? Do you like to work in an international, multidisciplinary team of professional experts for the next two years? Would you like to apply your innovative, creative ideas in developing future healthcare products in the high tech medical industry? Then you should consider starting as a PDEng trainee at TU/e and gain a head start on your fellow Master students!

Job description Professional Doctorate in Engineering' (PDEng)
During the traineeship you follow an individual program, consisting of courses, workshops, assessments and industrial projects, deepening the theoretical knowledge gained during your university studies. You will apply all knowledge gained in a large-scale in-company multidisciplinary design project. You build up a valuable network in the healthcare business community and can count on professional supervision from both the university and industry. Your individual training scheme is customized to your personal and professional skills, as well as the demands of the industrial project.

Wireless charging is typically based on magnetic induction, which requires that the power source and receiving device are in very close proximity to one another. These types of solutions typically require special alignment and charging docks. Far-field radiative RF power transfer offers a solution for continuous wireless power over a distance. This work focusses on harvesting RF energy at lower input power levels than state-of-the-art solutions, and offering a better operating distance than other radiative solutions.

Most of today's RF harvesters either have poor sensitivity, or require calibration, or a special technology process, or a large chip/antenna area. We want to focus on a design that consumes a small area, good sensitivity and wireless range performance. The IC design will focus on a combination of a rectifier and a boost-buck DC-DC converter. The challenge is to come to an adaptive rectifier design with a large voltage boost (and hence good sensitivity), but minimizing the drop in output current at the same time. The DC/DC converter will be co-designed with the rectifier to deal with fluctuating input conditions and load impedances, for an optimum power-point-tracking (PPT) system with high flexibility and adaptivity.

Outline of the project:
