Weighted voltage control design for DC/DC converter

In this paper, the design procedures of the weighted voltage control (WVC) network integrated referent command setting; current share control effort and voltage trimming function together are presented. In accordance to the location of this WVC network within DC/DC converter, two approaches are analyzed in detail by using the superposition theorem and linearized perturbation analysis. Owing to the integrated function of the WVC network, the measuring procedures of the current share loop transfer function are also introduced though proper controlling this WVC network and leads to design current share controller more easily. Finally, some simulations and experimental results of the paralleled operating 12 V/3.3 V/20 A buck converter are provided to show the effectiveness of this WVC network
