Enclose schematic diagram；Fig. 8 is bucking coil schematic diagram.
From figure 5-8 it can be found that the area coil of bucking coil significantly increases in the present invention.This is because wireless charging
The energy transfer efficiency of system is main related with the coefficient of coup, and the determinant of coefficient is area coil once in a while.It is different from tradition
The bilateral wireless compensating charge system balance area coil very little of LCC, is not enough to construct the Energy transfer of bucking coil, and the present invention increases
The big area coil of bucking coil, and when the increase of the area coil of bucking coil to a certain extent after, transmitting terminal bucking coil
Energy transfer is formed between layer 3, receiving end compensating line ring layer 4, hereafter as the area coil of bucking coil is gradually increased, passes efficiency
Rate gradually rises.
In conjunction with the performance advantage of the bilateral wireless compensating charge system of LCC of tradition, bucking coil and biography energy coil angle are
It 90 °, realizes bucking coil and passes the decoupling of energy coil.The present invention increases bucking coil area, bucking coil on the basis of this
While with energy coil decoupling is passed, and Energy transfer is constructed between bucking coil, and between bucking coil and biography energy coil
Without coupled relation, as shown in Figure 9.
Since bucking coil inductance value and area coil are smaller, the coupled systemes of the bilateral wireless compensating charge system of LCC of tradition
Number only has K1_2, and the coefficient of coup and efficiency have following relationship:
K --- the coefficient of coup；
Q1 --- transmitting terminal quality factor；
Q2 --- receiving end quality factor；
From the coefficient of coup with relationship between efficiency formula it is found that being only improved the coefficient of coup or improving quality factor just can be improved
The efficiency of transmission of wireless charging system, if not considering the influence of quality factor, it is known that the coefficient of coup is bigger, and efficiency is higher.
The present invention makes bucking coil generate coupling by the area coil of increase bucking coil, as shown in figure 9, in addition to passing
The coefficient of coup for compensating charge system that the bilateral LCC that unites is wireless only has K1_2, due to compensating the increase of inductance, in charging system simultaneously
There is coefficient of coup Kf1_f2, therefore therefore the coefficient of coup of whole system increases, according to the coefficient of coup and relationship between efficiency
Therefore more traditional bilateral wireless compensating charge system of LCC can improve the efficiency of transmission of wireless charging system known to formula.
According to the discussion of front, the bilateral wireless compensating charge system of LCC of tradition has in the Y direction due to its design feature
Very strong anti-excursion capability, since it is compensated, inductance coil area is smaller can not to carry out energy transmission, although bucking coil is same
Sample uses DD type structure side by side, but does not have anti-excursion capability in the X direction.The present invention is due to increasing bucking coil
Area coil, bucking coil equally have biography can effect.Therefore, side by side the anti-excursion capability of DD type coil also on bucking coil
It is embodied, the present invention also has certain anti-excursion capability in the X direction.
Simultaneously as angular position vertically realizes decoupling between bucking coil and biography energy coil, in coil design process,
Bucking coil, which can be ignored, and passed to influence each other between coil, only to bucking coil and the respective coupled relation for passing energy coil
Meter is erected, without the concern for the coupled relation of bucking coil and biography energy coil, reduces the design difficulty of whole system.
Compared with prior art, technical solution of the present invention has the beneficial effect that:
First, bucking coil is also equipped with biography energy effect in addition to reactive compensation, is formed specially between bucking coil and passes and can lead to
Road improves the energy transfer efficiency of system.
Second, it is different from the bilateral wireless compensating charge system of LCC of tradition, the area coil of bucking coil is smaller not to constitute hair
The Energy transfer of end, receiving end is penetrated, the present invention is opened by increasing the area coil of bucking coil from not having biography energy effect
Begin, as the area coil of bucking coil is gradually increased, when area coil increases to certain value, formation passes energy between bucking coil
Channel, and the channel energy transfer efficiency improves, i.e. the biography energy effect of bucking coil as the area coil of bucking coil increases
Related with area coil, in system integrated planning size range, area coil is bigger, and it is better to pass energy effect.
Third, bucking coil are 90 ° with biography energy coil angle, so that effective overlapping area of bucking coil and biography energy coil
Reduce, and then realize bucking coil and biography energy coil decoupling, therefore the Energy transfer of bucking coil and biography energy coil can be independent
Consider, separately designs the size of its coil and the parameters relationship of the coefficient of coup, reduce the design difficulty of system.
4th, compensating charge system that the bilateral LCC of tradition is wireless emits the DD type side by side of end-coil using DD type structure side by side
