Abstract: An inverter includes a bobbin and a first insulated wire. The bobbin includes a main body, a first base disposed on one side of the main body and connected with the main body, a first plate disposed between the main body and the first base, among which a wire groove is formed between the first plate and the first base, and a plurality of second plates disposed on the main body for forming a plurality of first winding grooves on the main body. The first insulated wire has a winding portion disposed in the first winding grooves and a first outlet partially disposed in the wire groove, such that the first outlet is staggered with the winding portion, thereby avoiding the short circuit phenomena of the first insulated wire caused by the tear abrasion, avoiding the arc burn phenomena, and having high voltage-resistance.

Abstract: An inductor assembly includes a base and an inductor component. When the inductor component is disposed on the base, the distance between the inductor component and a nearby electronic component is increased by a connecting element or a carrying element of the base, and the inductor component is prevented from contacting the nearby electronic component by a spacing element of the base.

Abstract: A surface mount magnetic device includes a magnetic core assembly, a winding coil and an extension region. The magnetic core assembly includes a first magnetic part and a second magnetic part. The second magnetic part has a first surface and a second surface. The first surface of the second magnetic part is connected to second magnetic part such that a receptacle is formed between the first magnetic part and the second magnetic part. The winding coil is partially accommodated within the receptacle and includes at least two pins, wherein the pins are attached on the second surface of the second magnetic part. The extension region is integrally formed on the second surface of the second magnetic part.

Abstract: A magnetic element includes a magnetic core assembly and multiple winding coils. The magnetic core assembly is used for proving a closed magnetic flux path and includes a first side plate, a second side plate, a first side pillar, a second side pillar and at least two middle pillars. The first and second side pillars are arranged between the first and second side plates and respectively disposed on bilateral edges of the first and second side plates. The at least two middle pillars are arranged between the first and second side pillars and includes a first middle pillar and a second middle pillar. The winding coils are wound around the at least two middle pillars.
