Ripple Estimation for Paralleled Converter System with Automatic Interleaving Function

Current ripple for any paralleled converter system under ideal out-of-phase operation is estimated with simplified circuit model. The ideal out-of-phase operation is achieved by introducing automatic interleaving function. Relationships between the ripple and circuit parameters such as duty ratio and number of modules are revealed which provide simple design guideline for ripple-minimized paralleled converter system.
