Abstract
The utility model designs a boost inductor, in particular a high-power boost inductor. The inductor comprises a magnetic core and a coil wound around the magnetic core. The high-power boost inductor is improved in that: the magnetic core is a square magnetic core; and the coil is wound from a flat wire stock which is greater than or equal to 15 mm wide and greater than or equal to 4 mm thick. The high-power boost inductor of the utility model is capable of allowing current above 185 A to flow through by means of a single flat wire, so that the high power output of the single inductor becomes possible; as the inductor is wound from the flat wire; the volume of the product can be effectively reduced; and the power intensity of the product is improved.
Description
Technical field
The utility model designs a kind of boost inductance, especially a kind of high-power boost inductance.
Technical background
Boost inductance more than tens kilowatts becomes high-power boost inductance, and existing high-power boost inductance is general to adopt a plurality of inductance parallelly connected, and each inductance uses single magnetic core, and conductor uses circular enamelled wire or square enamelled wire.There is following significant disadvantages in this class formation: 1. because during circular enamelled wire coiling inductance, its occupation efficiency is little, causes finished-product volume excessive, the power density of product is low; 2. adopt a plurality of inductance parallel connections, cost is higher; 3. inductance uses single magnetic core, and when being applied to the inverter of different capacity output, the requirement of its magnetic core size has nothing in common with each other, and is unfavorable for raw-material simplification and standardization.
Summary of the invention
The utility model provides a kind of high-power boost inductance that reduces small product size, improves the product power density.
To achieve these goals, the utility model adopts following structure:
It comprises magnetic core be wound in the coil on the magnetic core, its improvement is: described magnetic core is a square core, described coil is flat wire rod coiling, the width of said wire rod is more than or equal to 15mm, thickness is more than or equal to 4mm.
Preferably, described square core is spliced by a plurality of little magnetic cores.
In sum, the high-power boost inductance of the utility model can pass through the above electric current of 185A through single flat wire, just makes single inductance realize that high-power output becomes possibility; Owing to adopt the flat wire coiling, can effectively reduce small product size, improve the product power density.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1; High-power boost inductance in the present embodiment comprises magnetic core 1 and is wound in the coil 2 on the magnetic core 1 that wherein, described magnetic core 1 is a square core; Described coil 2 is flat wire rod coiling; The width of said wire rod is more than or equal to 15mm, and thickness is more than or equal to 4mm, and described flat wire rod can be through the above electric current of 185A.The coil 2 that flat wire rod is formed is little with respect to the coil space factor of original enamelled wire coiling.
In addition, described square core 1 is spliced by a plurality of little magnetic cores 1 ', and magnetic core adopts the mode of littler standard magnetic core splicing to make that application is more flexible, helps raw-material standardization and simplification.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
