Improving the cross regulation of multi-output SRC by adding the magnetic fence and capacitance compensation

In this paper, a novel method for improving the cross regulation characteristics in multi-output series resonant converter (SRC) is proposed. The proposed method is based on the theory of eddy demagnetization and series resonant. The proposed method is verified on a single input with four outputs SRC, the input of SRC is 12V with 24V in every output. Both the experimental results and FEM simulation are presented to demonstrate the theoretical analysis. The experimental results illustrate that the proposed method can improve the cross regulation characteristics in multi-output SRC, and make the outputs of multi-output SRC stable.
