Abstract
The issue of degraded power quality in server power supplies under light-load conditions is addressed by proposing a light-load power quality optimization control strategy.By analyzing the traditional control strategies and the characteristics of EMI filter circuits,an X-capacitor current compensation control strategy is proposed to improve the power factor under light-load conditions.A hybrid control strategy combining offset lifting,variable gain,and average current restoration in discontinuous conduction mode(DCM)is adopted to optimize the input current total harmonic distortion(THD)under light-load conditions.A 1 300 W server power supply prototype is developed.The experimentcl results demonstrate that the proposed optimization control strategy significantly improves power quality under light-load conditions,with both power factor and input current THD meeting the specification requirements,which verifies the effectiveness and superiority of the proposed strategy.关键词
