本文提出了一种使用串联补偿器 GCSC（门控串联电容器）作为初级侧电容器的无线功率传输系统。 GCSC是一种通过控制半导体开关而起到串联可变电容器作用的电路模块。将 GCSC 应用到初级侧电容器的优点是它为高频逆变器提供了输出功率因数的可控性。因此，通过控制输出功率因数，无论线圈参数如何，都可以实现高频逆变器的最佳运行。 1 kW 实验室原型的实验结果证实，所提出的系统可以实现高频逆变器的最佳运行和高效率。
This paper proposes a wireless power transfer system using a series compensator GCSC (gate‐controlled series capacitor) as a primary side capacitor. The GCSC is a circuit module that functions as a series variable capacitor by controlling semiconductor switches. The advantage of applying the GCSC to the primary side capacitor is that it provides controllability of the output power factor for a high‐frequency inverter. Therefore, optimum operation of the high‐frequency inverter can be achieved irrespective of the coil parameters by controlling the output power factor. Experimental results with a 1 kW laboratory prototype confirmed that the proposed system can achieve optimum operation and high efficiencies of the high‐frequency inverter.
