The PCDU modules, subject of this project, are dedicated to small Telecom GEO platform addressing the range of 2 to 5 kW.
The objective is to develop and qualify some specific modules, building blocks allowing to propose for such market a competitive "Power Conditioning and Distribution Unit" (PCDU) which is the heart of the electrical power system of any Telecom satellite.
For that purpose the following modules are manufactured and tested
Note that BCDR modules interfacing battery and bus have been developed in the frame of previous SATCOM development and therefore the development of BCDR module is not part of this project
In association with these modules an ATE (Automatic Test Equipment) is also manufactured in the frame of the project.
To illustrate the PCDU concept based on generic modules development, the modules are used in the PCDU of the EDRS (European Data Relay Satellite) Artes program of ESA for which the selected platform is the OHB one.
The challenge is to develop generic modules that could be used in PCDU of the target market small Telecom platform addressing the range of 2 to 5 kW with reduced customization.
The modules must be competitive in terms of cost and mass and must be based on mature and low risks technology / solutions
The main benefit brought by the project is the increased competitiveness in terms of development costs and time to market.
The goal of the generic modules is to be integrated to various PCDU applications based on the following common requirements.
The global Project plan is as follows:
The development of the modules is completed. The qualification of the modules in the frame of the validation of the EDRS PCDU is successful and the PCDU is delivered to OHB.
