The purpose of this paper is to describe a new generation of Power Conditioning Unit (PCU) developed to fulfil the needs of the Rosetta deep space mission. It will address the functional, electrical, thermal and mechanical aspects of the design. The energy source for the Rosetta deep space mission is solar panels. Batteries provide an energy storage facility to manage continued energy supply during eclipses and short-term peak power loading. The PCU regulates the spacecraft power required into one reliable, regulated 28 volt main bus supply line. The Rosetta spacecraft has to travel to a point, which is more than 5 AU from the sun, which reduces the available solar panel power to less than 1/25 of its power capability near earth. Thus, to limit the size of the solar arrays, it is mandatory for this mission to be able to utilise all the array electrical power.
