Abstract:A low voltage, high current, modular 50 V, 700 A dc power
supply has been developed to bias 35 number of 500 W, 505.8 MHz
solid state RF amplifiers. This power supply incorporates 7 number
of 50 V, 100 A ac-dc power modules, operating in parallel to share
the load current. This power supply has two unique attributes namely
modular hot swappability and active redundancy. Hot swappable
feature incorporated in power modules enables isolation of faulty
power modules and facilitates their online repla… Show more
