In this paper, a novel common mode inductor structure is proposed to achieve high power density for the EMI filter. For better utilization of space, planar core is adopted. In this new design, the core integrates both the CM and DM inductors. Response surface methodology is applied for better design of the inductor. Furthermore, bifilar windings are adopted for less interaction. Finally, some simulation...
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...
In this paper, a novel three dimensional integration of EMI filter is presented. Planar structure is adopted in this EMI filter design, including planar common mode inductor and planar capacitors. The principle of the novel planar common mode inductor is analyzed and the implementation of the planar capacitor is discussed. This proposed EMI filter can achieve good performance in high frequency and...
Current sensing in dc–dc converters is critical for protection and operation purposes of the system. This paper proposes a novel lossless current-sensing technique based on the matching complementary filter topology whose main idea is to transform the current signal to voltage signal. This new technique introduces a thermal compensation block to improve its accuracy, an error elimination block to...
