Abstract

To increase the output dynamic response and decrease the stable ripple of VRM, With multi-core combination, a split-phase coupling array integration inductance (short for SCAII) is applied in the four-phase VRM. Without considering the impact of leakage magnetic flux, the effect of SCAIIpsilas parameters is analyzed on the performance of VRM. The SCAIIpsilas complanation structure, is given and using electromagnetic field finite element software complanation SCAII VRM is analyzed. Using circuit simulation software the SCAII is compared with the separation magnetics. The simulation results show the correctness of the theory and experimental results showe that four-phase SCAII VRM has preferable dynamic effectiveness.
