Zusammenfassung:A magnetic apparatus with symmetric quadruple or octuple winding arrangement is provided. The magnetic apparatus includes a winding substrate provided with pairs of windings and a multiple-leg magnetically permeable core assembled on the winding substrate. Current self-equalization results from control signals with progressive phase offsets between groups and a phase offset of 180 degrees within groups. A power module including the winding substrate, the windings, a high-voltage circuits including bridge arms of switches and resonance branches, and low-voltage circuits including synchronous rectifiers, and with a DC input are used to form a DC-DC conversion device. Multiple circuit topology is provided and implemented in the structures of the power module and the DC-DC conversion device.
