摘要:
研究了磁共振式无线电能传输的传输效率,指出获得高传输效率的关键在于提高谐振电路的品质因数; 针对高品质因数谐振电路的易失谐性,提出一种基于相控电容的谐振电路调谐方法:通过改变相控电容的相位角,等效形成一个可变电容,用此可变电容对谐振电路进行调谐,从而稳定传输效率和功率。分析相控电容调谐原理,设计相控电容调谐电路,给出相位与等效电容之间的对应关系,并采用仿真和实验的方法对其调谐特性进行了验证。结果表明: 相控电容调谐具有一定的可行性,可使磁共振式无线电能传输在耦合改变时,通过谐振补偿来维持电能传输的稳定性,因而对其推广应用具有重要意义。
Abstract:
The transmission efficiency of the magnetic resonant wireless power transfer is studied,which reveals that the quality factor of the resonant circuit is the key to achieving high transmission efficiency. For the detuning of the high quality resonant circuit,a turning method based on the phase-control capaci-tor was addressed; A controllable capacitor was achieved by adjusting the phase angle of recharging. Thus, the transmission efficiency and power of wireless power transfer can maintain stable by using this phase-control capacitor. The theory of phase-control turning was analyzed. The circuit of phase-control capacitor was discussed,and the relationship between the equivalent capacitor and the phase angle was calculated. Then,simulations and experiments were carried out to verify the validity. It shows that the proposed meth-od is feasible,and important to the application of wireless power transfer due to mproving the transmission quality.
