Integrated power-converting module

An integrated power-converting module electrically connected to a direct current electric power, the integrated power-converting module comprising:

• a bobbin comprising a main body, a plurality of winding portions, and a plurality of receiving portions, the main body having a first channel and a second channel communicating with the first channel and perpendicular to the first channel, the winding parts portions and the receiving portion portions arranged in a staggered manner, each receiving portion having a slot communicating with the first channel;
• a primary coil wound on the winding portions;
• a magnetic core assembly assembled with the bobbin and partially received in the first channel;
• and
• a plurality of power-converting units arranged in a parallel manner and each of the power-converting units comprising:
• a circuit board having a base portion and an expending extending portion connected to the base portion, a penetrating hole and a secondary winding formed on the expending extending portion, wherein the extending portions are portion is respectively inserted into the slots slot, and the penetrating hole is corresponding to and communicating with the first channel;
• a rectifier placed on one of surfaces of the base portion and electrically connected to the circuit board;
• and
• a filter placed on the other surface of the base portion opposite to where the rectifier placed on and electrically connected to the rectifier,
• wherein when the direct current electric power is conducted to the primary coil, the magnetic core assembly generates electromagnetic induction, and a converted power is generated on by the secondary windings of the power-converting units, wherein the filters of two power-converting units disposed on two opposite sides of and most close to the second channel face each other.
