Superior part-load efficiency is another virtue in the proposed system, for the input current of the resonant tank is decreased with the decrescence of load.

同时谐振槽输入电流随负载的减小而减小，提高系统的部分负载能效值。

By the resonant tank parameters obtained from the proposed method, a 220W phototype was built up, and the experimental results verified the improved design method.

基于所提出的方法设计的参数建立一台220 W的样机，实验结果证实了所提出改进型设计方法的正确性和可行性。
