Abstract :
We are developing a system to provide isolated power to the filament power supply of an X-ray tube located at a potential of several hundred kilovolts. In this design a fiber-optically connected photonic power system (PPS) is used to recharge a lithium-ion battery pack, which will subsequently supply power to the rest of the system. This paper evaluates the suitability for using the commercially available JDSU Photonic Power System for charging Li-Ion batteries. The output of the PPC converter is characterized. The technical aspects of its use for charging a variety of Li-ion batteries are discussed. Battery charge protection requirements and safety concerns are also addressed.
