Also important is the minimum frequency that full power is possible - this indicates the amount of primary inductance and the quantity and quality of the core material.

而且，全功率输出时的最低频应指标亦为重要，因为这能显示出铁芯材料本身的初级电感量、质量、及其铁片数量。

In order to improve both charge current and transfer efficiency via a lower coupling coefficient inductive link, class E power amplifier based on primary leakage inductance and compensat.

在低耦合系数条件下 ，通过基于初级漏感的E类功率放大器和次级漏感的补偿方法 ，提高电容充电电流和传输效率。
