本发明中，提供了一种多谐振电路并联的磁耦合共振电能***，如图2所示，该磁耦合共振电能***01中包括多谐振电路并联的磁耦合共振电能发射端02，多谐振电路并联的磁耦合共振电能接收端03，发射端02将电能转化为电磁能、接收端03将电磁能转化为电能，所述发射端02中包括两个或两个以上的发射电路单元04，每个发射电路单元04包括发射谐振电路05、以及用于驱动发射谐振电路05的逆变电路06，各逆变电路06输入端并联；所述接收端02包括接收电路单元07，所述接收电路单元07数量与前述多谐振电路并联的发射端02中发射电路单元04数量相同，且每个接收电路单元07包括与所述发射电路单元04中发射谐振电路05对应设置的接收谐振电路08、以及整流输出电路09，各整流输出电路09输出端并联。
其中，所有发射谐振电路05中的谐振线圈组成发射线圈阵列，构成所述发射线圈阵列的各谐振线圈同平面设置，构成所述发射线圈阵列的各谐振线圈为平面型线圈；所有接收谐振电路08中的谐振线圈组成接收线圈阵列，构成所述接收线圈阵列的各谐振线圈同平面设置，构成所述接收线圈阵列的各谐振线圈为平面型线圈；所述发射谐振电路05和接收谐振电路08中的谐振线圈的电感值相等；在实际应用中，发射线圈阵列中的谐振线圈和接收线圈阵列中的谐振线圈对应设置。无论是构成发射线圈阵列的各谐振线圈，还是构成接收线圈阵列的各谐振线圈，其各谐振线圈彼此间不重叠。如图4所示，谐振线圈L1、L2同平面设置。在一优选地实施方式中，该各谐振线圈间的预设间隔距离尤以不小于5cm为优。
所述发射谐振电路05和接收谐振电路08中均串联有补偿电容，所述发射谐振电路05和接收谐振电路08中的补偿电容的电容值相等；所述发射谐振电路05和接收谐振电路08均为CLC谐振电路。
在本发明的磁耦合共振电能***01的发射端02中，所选取的两个或两个以上的发射谐振电路04设计，均能实现所要解决的MOS管不能过大电流，以及如何降低谐振电容工作电压，进而降低成本，推动无线充电在电动汽车充电领域的普及应用的问题，尤以两个发生谐振电路04设计为最佳。下面针对采用两个发生谐振电路04的最佳实施方式作为实施例加以阐述。
在该具体实施例中，如图3所示，直流电压电源为U，两个发射谐振电路(补偿电容C1、谐振线圈L1和补偿电容C2构成一个发射谐振电路，以及补偿电容C3、谐振线圈L2和补偿电容C4构成另一个发射谐振电路)，对应的两个接收谐振电路(补偿电容C5、谐振线圈L3和补偿电容C6构成一个接收谐振电路，以及补偿电容C7、谐振线圈L4和补偿电容C8构成另一个接收谐振电路)；其中，
C1＝C2＝C3＝C4＝C5＝C6＝C7＝C8
L1＝L2＝L3＝L4
谐振频率f＝85000HZ，计算公式为：
Figure PCTCN2017104460-appb-000001
上述公式中，L＝L1＝L2＝L3＝L4
C＝C1+C2＝C3+C4＝C5+C6＝C7+C8
具体的，直流电压电源U的直流电压输出后，当施加在逆变电路开关管的PWM(Pulse Width Modulation，脉冲宽度调制)的驱动信号为方波时，(该PWM开关频率为85千赫兹)直流电压被逆变成85000赫兹的交流方波电压，该方波电压驱动C1L1C2发射谐振电路和C3L2C4发射谐振电路发生谐振，在空间内产生交变磁场，接收端的C5L3C6接收谐振电路和C7L4C8接收谐振电路与发射谐振电路产生共振，共振正弦电压经整流输出电路变成直流电压Vout后输出。
在该磁耦合共振电能***的发射端中的逆变电路为全桥逆变电路，所述全桥逆变电路的PWM开关频率为85千赫兹；所述整流输出电路为桥式整流电路。
上述多谐振电路并联的磁耦合共振电能***中的多谐振电路并联的磁耦合共振电能发射端02、多谐振电路并联的磁耦合共振电能接收端03分离设置，发射端02接入有直流电压电源，接收端03连接有输出电压，比如在电动汽车领域，发射端02设置在充电站、接收端03设置在车体内，只有在电动汽车充电时，发射端02和接收端03相互配合，实现电能的无线传输。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
