摘要
推导了在斩波电路中采用随机脉冲位置(RPP)策略和随机载波频率(RCF)策略开关函数的功率谱密度(PSD)解析表达式。通过引入随机变量的特征函数,详细讨论了随机变量的分布对PSD的影响,为随机脉宽调制技术的设计提供了有效途径,仿真分析和实验结果的对照验证了表达式的正确性。
The closed-form equations for PSD of RPP method and RCF method were derived.By introducing the character function of random variable,the effect of the distribution variables on PSD was studied in detail and the optimization PSD was proposed.The equations were verified by the experiment results.
