Single electronic power conditioner for integrated payloads of communication satellites

Abstract

This paper discusses the design of an electronic power conditioner (EPC) that caters to an entire regenerative payload of spacecraft. The EPC in this particular case is capable of handling 25W output power distributed amongst thirteen outputs of respective subsystems i.e. FPGA based digital filter, Solid State Power Amplifier, Up converter, Low-Noise Amplifier (LNA) etc. The paper presents a compendium of the application wherein the EPC has been employed with all of the subsystems' specific requirements including individual Telecommands as well as requisite delays in startups of output voltages with pre-defined time periods and highlights the design of the same.
