Abstract

There are mainly two kinds of DC power supply voltages such as 28V, 42V in small and medium power level satellites. A novel cascaded current fed DC/DC topology which can cover all these input voltages was proposed. The working principle of the cascaded topology which composed by a Buck converter cascaded with a current fed push-pull converter was analyzed. With a synchronous rectifier circuit, high output current can be offered efficiently. A unique magnetic feedback scheme for space applications was also proposed. The experimental prototype had been built here and testing results were also analyzed.
