Two power supplies have been developed by the Space Engineering Research Team of the Wigner Physics Research Center for the PEP Plasma Physics Instrumentation (PI Stas Barabash, IRF, Kiruna, Sweden), the integration of the first flight unit began at the University of Bern in early August . PEP will be launched on its nine-year journey on an Ariane rocket in May 2022 as part of the ESA Juice project. The aim of the project is to research Jupiter and its moons.

The two power supplies developed by the Hungarian group led by János Nagy were named NU_DCC and JDC_DCC  (Nadir Unit Direct Current Converter, Jovian plasma Dynamics and Composition Analyzer Direct Current Converter), and their task is to provide power for 2 processor cards and 4 sensors. The integration started after the 3 shipped cards of the NU_DCC were installed in the mechanical frame. Based on the tests, all devices have been working properly so far. The integration will last until the end of September. PEP's goal is to study the interaction between Jupiter's magnetosphere and its moons and the effect of the solar wind around Jupiter.
