Abstract:

Aiming at the requirements of miniaturization of satellite equipment and lightweight of the whole system,a design scheme of anti radiation POL power supply with 4.5~16 V wide voltage input and dual-channel output is proposed.Firstly,the topology structure of the circuit is designed according to the requirements of the power supply index.Secondly,the solution of anti-radiation index is proposed.Finally,the difficulties of process design are studied and solved.The proposed power supply is realized by simulation and prototype verification.It has the advantages of small volume,light weight and high power density and so on,which can provide miniaturized and lightweight tertiary power supply solutions for aerospace electronic equipment systems.
