In the updating and upgrading of aircraft power supply system, DC power supply will become mainstream strategy. The standard GJB181B-2012 explicitly states that critical utiliza-tion equipment should endure 50 ms power interruption characteristic produced by bus or power supply conversion. A capacitance energy storage method for 50ms power interruption is intro-duced, the problems of this method such as expensive cost, surge current are analyzed, a new capacitance energy storage method based on boost convertor and a limited current startup meas-ure are proposed. These two methods improves the security and reliability of the airborne equip-ment availably.
