Abstract

Paper bases on the principles of the coupling inductor to illustrate the planar integration of two resonant inductors and one filter inductor in the ZCS buck QRC, all three inductors are integrated in one magnetic core, then the decreasing in the volume and height can be achieved, through comparing the close coupling with the loose coupling, how to achieve the soft switching is discussed, and the stable output voltage is guaranteed too. The simulated results of the circuit and the flux line are also included in this paper
