The present disclosure relates to a power module. The power module includes an inverse-coupled inductor and a plurality of half-bridge modules. The inverse-coupled inductor includes: a plurality of windings and a magnetic core. The plurality of windings are linear windings between a first plane and a second plane. The first magnetic core and the second magnetic core are located at both ends of each of the windings, the magnetic core pillars connect the first magnetic core and the second magnetic core to form a plurality of magnetic core units, and the plurality of magnetic core units surround corresponding windings in a same direction from the first plane to the second plane. Projections of the plurality of magnetic core units on the first plane form a plurality of closed areas.

Power module, power supply system and multi-phase inverse-coupled inductor

The disclosure provides a power supply module, including a transformer including magnetic core and winding, and a rectifier circuit electrically connected to the winding, wherein the magnetic core further comprises: a first and a second cover plate opposite to each other; a first magnetic column; and a second magnetic column having a magnetic flux in opposite direction to that of the first magnetic column, the first and second magnetic column connected between the first and the second cover plate; the winding further includes: a first winding wound onto the first magnetic column; and a second winding wound onto the second magnetic column, wherein the first and second winding have a shared winding portion at least partially located between the first and second magnetic column; the rectifier circuit includes a plurality of rectifier components including first to fourth rectifier component electrically connected to form a full bridge rectifier circuit.
