摘　　要：非接触供电主要采用串联耦合谐振和并联耦合谐振实现能量的传递,谐振电路中L和C以静态的串联、并联形式连接存在,根据半桥变换器拓扑电路的特点,改变有极性电容为谐振无极性电容,在负载为电感的情况下,通过调节全控型开关工作频率,实现负载电感L与半桥电容C的动态并联谐振,从而完成能量的非接触传输。Abstract： The contactless inductive coupled power circuit could transfer power mainly by use of the series coupling resonance and parallel coupling resonance, L and C are connected by static series and parallel style in resonance circuit, according to the characteristic of half bridge converter topology, that the polarized capacitors is transformed to no-polarized resonance capacitors is to realize the load L and half bridge capital C dynamic parallel resonation by altering the frequency of full-controlled switch under inductance load circumstances, so the power is transmitted by the contactless style.
