摘　　要：通过改变频率、占空比和ＲＰＷＭ 方案来检测ＲＰＷＭ 对Ｂｕｃｋ 变换器的影响，以证实一种减少ＤＣ 变换器的噪声和电磁辐射的有效方法。结果显示了系统工作在不同的参数条件下，输出电压中纹波电压幅值和噪声电压幅值的变化规律。最后分析归纳了实验结论。The system was designed and the experiment was done to test RPWM on a buck converter by varying the frequency, the average duty ratio, and the RPWM schemes to prove an effective method in providing noise and radiation reduced dc. to dc. conversion. The system was run under a range of operating conditions and results were presented in terms of the noise amplitude of the continuous noise spectrum and the ripple amplitude presented in the output voltage. A summary of the results was drawn.
