IFEC 2020 - Power Supply for Nano Satellites
IFEC is an international student competition for innovation, conservation, and effective use of electrical energy, which is open to college and university student teams from recognized undergraduate engineering programs in any location.
The competition is sponsored by the Institute of Electrical and Electronics Engineers (IEEE) Power Electronics Society (PELS), Power & Energy Society (PES), Industry Application Society (IAS) and Power Sources Manufacturers Association (PSMA).
Background of IFEC 2020 Topic
Nanosatellites are one of the fast-growing satellite industry segments in recent years. According to Nanosats.eu, more than 1000 small- and nanosatellites have been launched as of the January of 2019 with an estimated market value over US$7 billion. As the costs are going further down and the production period is continuously shortening, the market of nanosatellites is still growing at a fast pace. The applications of nanosatellites are also very broad, covering global tracking, internet of things, remote sensing, defense and security, electronic equipment testing, etc.
Typically, nanosatellites have a wet mass between 1-10 kg (i.e., 2.2 – 22.0 lb). In this case, the design of nanosatellites requires much more dedications, especially the electronics, which is the core of the nanosatellites power systems. In general, the power electronics systems have to withstand the harsh operating environment, where the temperature is low and the equipment is exposed strong radiations. Additionally, the power conversions should be highly efficient and highly reliable to condition the power from solar photovoltaic (PV) panels, in which the power management is essential. The voltage levels at the PV should be regulated to be compatible with the load demands, e.g., battery storage systems and on-board loads. Those involve extensive direct current (DC) to DC power conversions, unidirectional and bidirectional. Notably, the space (volume and weight) is also a limiting factor when designing the power systems.
With the above considerations and background, IFEC 2020 is calling for proposals to design power supplies for nanosatellites applications. The power supplies include power sources from multiple solar PV panels (two) mounted on the surfaces of the nanosatellites. Batteries are used as the energy storage system, which are charged through the solar PV panels and discharged to supply loads when necessary. Different types of loads are considered. Thus, the power converters include unidirectional DC-DC converters and a bidirectional DC-DC converter for the batteries. The designed power supplies should perform the basic functions – extract the maximum power from solar PV modules; charge and discharge the batteries.
Topic: Power Supply for Nano Satellites
2x DC inputs: Max power < 60 W, Max current < 3 A, voltage 20 V
3x DC outputs: 3.3 V @ 5 A, 5 V @ 4 A, and 8 V @ 2600 mAh
Functionalities: MPPT control (uniform and non-uniform solar irradiance)
Functionalities: Battery charging and discharging
Judgment criteria: Functionality, efficiency, power density, and cost.
Participation is on a proposal basis. Those schools that are interested must submit a proposal to the topic chair before the proposal deadline. Each Proposal will be judged by a distinguished panel of volunteer experts from the IEEE and from industry. Schools with successful proposals will be notified and qualified for the rest of the competition. Deadline for each period will be posted on the IFEC website. The finalist teams will be invited to a competition event in summer of 2020.
There will be a Grand Prize of $10,000 and three additional awards granted at $5,000, $3,000 and $1,000 each.
Each university can support only one team.
Each team should have at least 4 members.
Interdisciplinary teams are encouraged.
Teams should be composed of primarily undergraduate students.
Graduate students can participate in team to provide high-level support.
