With the development of the distributed power system, the paralleled switching mode power supplies are becoming more and more important for large current load. However, paralleled system usually requires load sharing to equalize stresses, and while a lot of techniques have been used, there are many compromises between complexity and performance. This paper introduces the superiority of the power supply modules in parallel, discusses both the advantages and disadvantages of the usual current sharing methods. Finally, some suggestions to enhance redundancy and reliability for current sharing modules have been proposed.
