英文摘要:

This paper gives the design of a DC surge generator of two-stage conversion, used to generate surge test voltage for airborne DC equipment specified in GJB181A and RTCA/DO-160 standards. Buck+bridge circuit is used as main power topology to generate 28V and 270V DC voltages, DSP is used as controller to realize all-digital control, and variable speed integration is used to achieve quick response of output voltage. System design and prototype test verify the feasibility and practicability of the design scheme.
