| Abstract: |
| According to the particularity of the power circuit design requirement for space
electronics equipment working under special condition, this paper analyses its
power supply environment and the operation principle of power source converter,
provides the general design principle of the periphery protection circuit when t
he integrated DC/DC converter is used, proposes the commonly used power source p
rotection circuit scheme for spaceborne and rocket/missile-borne electronics e
quipment, and gives suggestion of control indexes for the protection circuit des
ign parameters. |
