摘要
研究了在负载变化时的新型E类放大器磁耦合谐振式无线电能传输系统的效率。首先,对新型E类放大器进行了理论分析和数学建模。然后,通过在新型E类放大器上采用前端阻抗转换器实现了放大器的开关管的ZVS、ZDS条件;并采用后端阻抗转换器实现了负载变化时效率的稳定性。最后,通过MATLAB对该系统进行仿真研究。仿真结果表明,在新型E类放大器中加入双端阻抗转换器后,放大器在负载变化的情况下,负载效率更加稳定。
The efficiency of a new class E amplifier magnetically coupled resonant wireless power transmission system is studied when the load changes. Firstly,the theoretical analysis and mathematical modeling of the new class E amplifier are carried out. Then,the ZVS and ZDS conditions of the switch of the amplifier are realized by adopting the front-end impedance converter in the new class E amplifier,and the efficiency stability of the switching load is realized by using the back-end impedance converter. Finally,the simulation of the system is carried out by MATLAB. The simulation results show that the load efficiency of the amplifier is more stable under the condition of load change after adding double ended impedance converter in the new class E amplifier.
