Post 13, left coil 14 and right coil 15 are constituted, and wherein left coil 14 is connected with right coil 15, so as to constitute an independent reactance
Device, is had the following disadvantages using above-mentioned reactor：The part of reactor is relatively more, loss ratio is larger；The coiling side of left and right coil
Formula is multi-layer flat winding, and production efficiency less trouble is high, and the layer insulation of left and right coil easily punctures；The total losses master of reactor
To be made up of left and right iron core and left and right coil loss, account for 40% or so of inverter total losses, so that photovoltaic DC-to-AC converter
It is less efficient.
But in view of the shortcomings of the prior art, developer be necessary to develop a kind of reasonable in design, simple structure, loss compared with
Low, overall weight is less single-phase vertical around magnetic integrated reactor compared with light, to improve photovoltaic DC-to-AC converter efficiency and overall dimensions.
Utility model content
To solve the problems, such as prior art, the utility model purpose provides a kind of reasonable in design, simple structure, damage
Consume relatively low, overall weight less single-phase vertical around the integrated reactance of magnetic compared with light, to improve photovoltaic DC-to-AC converter efficiency and overall dimensions
Device.
To solve above technical problem, what the utility model was realized using following technical scheme：
It is a kind of single-phase vertical around magnetic integrated reactor, including upper yoke and lower yoke, on described between yoke and lower yoke
Multiple stems are interval with along its length, it is characterised in that be provided between two adjacent stems every magnetic core post, every
Coil is wound with one stem.
In a preferred embodiment of the present utility model, on described between yoke and lower yoke along its length between
Every 2 stems are provided with, it is provided between 2 stems every magnetic core post, the upper end every magnetic core post is arranged on upper yoke, described
It is arranged on lower yoke every the lower end of magnetic core post.
In a preferred embodiment of the present utility model, the coil stands be wound on stem from top to bottom, the coil
End of incoming cables be arranged on the upper end of stem, the leading-out terminal of the coil is arranged on the lower end of stem.
In a preferred embodiment of the present utility model, inlet wire wiring hole is offered on the end of incoming cables of the coil,
Outlet wiring hole is offered on the leading-out terminal of the coil.
Compared with prior art, the utility model is interval with multiple along its length between upper yoke and lower yoke
Stem, and be provided with every magnetic core post between two adjacent stems, adopt the structure and not only reduce loss, and make whole
Body physical dimension is smaller, lighter in weight, further increases the operating efficiency of photovoltaic DC-to-AC converter.
