Abstract：The isue of degraded power quality in server power suppliesunder light-load conditions is addressed byproposinga light-load powerqualityoptimization control strategy.Byanalyzing thetraditional control strategies and the characteristics ofEMI filter circuits，an X-capacitor currentcompensation control strategy is proposed to improve the power factor under light-load conditions.A hybrid control strategycombining ofset lifting， variable gain，and average currnt restoration in discontinuous conduction mode （DCM）is adopted to optimize the input current total harmonic distortion（THD）under light-load conditions.A13Oo Wserver powersupply prototype is developed.The experimentcl resultsdemonstrate that the proposed optimization control strategy significantly improves powerqualityunder light-load conditions，with both power factor and input current THD meeting the specification requirements，which verifies the ffctiveness and superiority of the proposed strategy.

Key words： server power supply; light-load power quality ; X -capacitor current compensation; hybrid control strategy
