The influence on the power transfer and the current ripple with different turns ratio was researched. The experimental results verified the analysis.

文章研究了采用不同的正激、反激变压器匝比对传输功率的分配比例、电流纹波等影响，并进行了试验验证。

Finally, a solution to restraining the harmonic current and ripple torque is suggested, ie a larger modulation frequency ratio of 3k is to be adopted, as it is used in SPWM.

文中还提出了抑制谐波电流和脉动转矩的方法，如在SPWM生成中，采用较大的3的整数倍调制比。
