摘要: According to various embodiments, a power converter circuit is disclosed. The power converter circuit includes at least two vertically stacked printed circuit boards (PCBs) comprising a top PCB and a bottom PCB. The power converter circuit further includes at least one multiphase coupled inductor placed between the top PCB and the bottom PCB. The top PCB is coupled to the bottom PCB via at least one conductive winding of the multiphase coupled inductor. The power converter circuit further includes at least one circuit module placed above the top PCB and at least one power source placed below the bottom PCB. The multiphase coupled inductor is configured to deliver current vertically from the bottom PCB to the top PCB.
