The simultaneous development proposed in the frame of this activity will allow to optimize the commonalities between the two PPUs and to reduce the development costs by looking for similar electrical architecture, packaging concepts and technologies. Ultimately, the two PPUs resulting from this activity will be coupled with HEMPT and HET thrusters developed in the frame of two H2020 EPIC programmes.
 
The activity will be executed in 3 steps:

The project focused on the development of technology for wireless energy transmission from a fixed station to a vehicle. A rover-like vehicle on the surface of the moon was assumed for the definition of the system parameters. Previous studies and projects for SPS WPT systems focused on the frequency ranges at 2.4GHz or 5.8GHz and less in the mm-wave range when selecting the transmission frequency. The reason for this is the lower attenuation of the transmission through the atmosphere.

Energy generation in Space poses a severe challenge, the answer to which may be the use of novel metamaterials for thermoelectric generators. Metamaterials can address this question by employing conventional materials and well-established fabrication technologies while leaving room for other approaches to increase the efficiency of thermoelectric generation. In the current study, we investigated possible configurations of metamaterials that could increase the efficiency of thermoelectric generators in Space.

For a given application area, the power and propulsion requirements may evolve with each generation of the satellite system. Power levels may increase with the enhancement of the payload and also the introduction or the increased use of electric propulsion. These trends are occurring in application segments such as navigation. In order to address these trends, power subsystem solutions may be adapted from satellite systems used for other orbits and other applications.

High voltage and high switching speed DC-DC converters based on Gallium Nitride (GaN) technology offer a revolutionary breakthrough for the next generation of power systems. Moving from Silicon (Si) to GaN, will mean power-conditioning subsystems with better efficiency and reduced mass/volume (50%). GaN transistors also offer the inherent ability to operate at higher voltages than Si and with improved radiation tolerance. All of these attributes are important for space application.

New space applications and present thoughts about use of Commercial Off The Shelf (COTS) components resulted in the massive use of non-hermetic packages for a number of active analogue, digital or mixed Application Specific Integrated Circuits (ASIC), to combine both performances and cost reduction. One extremely attractive option is to put in plastic package a radiation hardened component, for which full traceability can be demonstrated.

The aim of the work has been to develop an efficient and robust turbine demonstrator that can efficiently operate under Mars environmental conditions. A combination of low friction and high inherent triboelectric charge density materials have been integrated into the Triboelectric Generator (TEG) architecture operating under a freestanding mode and including 4 generators. Each generator is compounded by Al+PTFE stator and H-DLC+Al rotor and the complete efficient design has 2 rotors and 4 stators.
