- Abstract:
- In order to address the issues that the magnetic coupled resonant wireless power transfer(MCR-WPT)system is sensitive to the resonant frequency and that transmission power is difficult to control with the non-resistive load in the MCR-WPT, a single-side regulation scheme for frequency and transmission power online is proposed, which is based on the inherent constraint relationships the among system parameters in the primary side. Thus, the communication between the primary side and the secondary side is avoided. First, the transfer models of resistance-capacitance load and resistance-inductance load are established, respectively. Next, the relationship between the input voltage phasor and the input current phasor is used to recognize the load property and value. Then, the coaxial rotation of the stepper motor and the rotating vacuum variable capacitor is conducted to unify resonant frequency both in the primary side and the secondary side. Finally, the regulations of both frequency and amplitude of input voltage are made to guarantee transmission power under a new resonant frequency point the same as the one when the only pure resistance part of load is accessed under the former resonant frequency point. Both simulation and experimental results indicate that the proposed regulation scheme can track resonant frequency and maintain transmission power constant.
- 为了解决磁耦合谐振式无线电能传输系统频率特性尖锐及非阻性负载接入时传输功率难以控制的问题, 基于系统初级侧参数固有的约束关系, 提出了一种单侧功-频在线控制策略, 从而避免两侧之间建立通讯.分别建立系统在阻容性和阻感性负载接入时的传输模型, 利用初级侧输入电压相量和输入电流相量的关系对负载性质和大小进行辨识;利用步进电机和初级侧真空可调电容的共轴旋转调整容值以使得初级侧谐振频率和次级侧谐振频率一致;调节输入电压频率和幅值以保持系统在新的谐振频率点下传输功率与在原谐振频率点下仅接入该负载阻性部分时的传输功率一致.仿真和实验结果表明, 所提出的控制策略能够准确地实现谐振频率的跟踪和传输功率的恒定.
