ESA Graduate Trainee in Power Systems

Job Description:

Location

ESTEC, Noordwijk, Netherlands

Our team and mission

The power management and distribution section is a very lively, social and competent group of people, with a really great work atmosphere. EGTs, trainees and Research Fellows are fully integrated in the section and participate to all meetings. They have access to support from all members of the section as needed. The section takes care of:

* Power system architectures. Working on the optimum architecture definition and the overall sizing of the system, linking with the colleagues from the solar array and battery sections
* Primary power system units. Working on the topologies and features of the main power conversion units
* Secondary power conversion. Working on DC/DC converters, control systems, protections, etc
* Distribution system. Working on the safest and most efficient way to distribute protected power to all units

Technologies for power conversion. Working on the use of GaN and SiC switches, digital control, new topologies, etc.
Apart from the assigned tasks, EGTs and trainees are welcome to participate in any other activity going on in the section if they are particularly interested in them.

You are encouraged to visit the ESA website: http://www.esa.int

Field(s) of activity/research for the traineeship

The proposed training project consists in one or several of the following tasks:

On the Power Systems area:
* Build generic simulation models of the main power system types
* Build generic 3D models of the most typical satellite configurations
* Build a generic behavioural model of all power units
* Build a generic functional model of all power units
* Build and test a full power system architecture with the models developed
* Develop an alternative power system sizing method to reduce system margins

On the DC/DC converter area:
* Design and test new power topologies with GaN devices
* Design and test new digital control strategies with FPGAs or microcontrollers
* Design and test electronic protection systems
* Design and test electronic motor drives

All activities that entail relevant breadboard realisation and test can be done in our lab.

For analyses, advanced model and simulation tools are available (LTspice Simetrix/Simplis, Matlab, Jupyter, Mathcad, EcosimPro. etc).

For breadboard and tests, relevant electrical/electronic components, tools and instrumentation are available in the labs (solar array simulators, power and signal generators, scopes, sensors, active and passive loads, network analyser, impedance test bridges, etc).
