本文提出了一种非线性电容式WPT系统,该系统自动补偿在没有有源电路的电容式无线功率传输(WPT)系统中的发射器和接收器之间的耦合变化。该系统能够在13 MHz的固定工作频率下,随着耦合距离的变化,输出功率的变化最小。与传统的电容式无线电力传输电路相比,在宽范围的耦合电容变化上实现恒定的输出功率。这种方法对于采用电容式WPT系统的生物医学植入物是有吸引力的。
This paper presents a nonlinear capacitive WPT system that automatically compensate for the coupling variation between the transmitter and receiver in a capacitive wireless power transfer (WPT) system with no active circuitry. The system is capable of minimizing the output power variation at a fixed operating frequency of13 MHz as the coupling distance varies. A constant output power is achieved over a wide range of coupling capacitance variation in comparison to the conventional capacitive wireless power transmission circuits. Such an approach is attractive for biomedical implants employing a capacitive WPT system.
