Abstract

The MPBUS communication system is a unique technology designed to enable data transfer over common DC power lines. Eliminating wires can enhance the performance of aerospace systems by reducing weight, simplifying installation of components and maintenance as well as increasing system reliability. The power lines in space systems feed many actuators, sensors and switching power inverters that impose noise on the DC lines. Powerline Transceivers that were designed specially to operate under these harsh conditions are described. It is demonstrated how the MPBUS is employed for battery management and for providing sensors/actuators network while eliminating existing data-carrying cabling; i.e. more functionality is added with less cabling. EMI/EMC issues are also discussed.
