摘要 开关频率调制技术是改善功率变换器EMC的一种有效方法,不同的扩频信号的扩频效果是不同的。在隔离式双正激DC/DC功率变换器的基础上,分别对周期性信号、随机信号和混沌信号作为开关频率调制信号对功率变换器EMI的抑制效果作数值上的分析,指出它们各自的优缺点。认为相对而言,混沌信号是一种比较理想的扩频信号。 Switching frequency modulation technology is efficient in improving EMC of switching power converters. Based on a diagonal half-bridge forward power converter. The discrepancy of E MI suppression effect of different spread-spectrum signal in theoretical, such as periodic signal, random signal and chaotic signal is analysid. Chaotic signal is thanked relatively superiority in view of their advantages and disadvantages.
