Abstract :
Digital control is now being applied to control the plant voltage and current sharing among paralleled rectifiers in a telecommunications battery plant. The stability analysis of this scheme is needed to ensure robust performance and maintain the reliability of the plant under a variety of different operating conditions. The analysis also provides design criteria that can lead to optimal time response of the current-sharing loop in the battery plant,
