混合系统是已知的电磁干扰的潜在来源，由于其反复开关的电压和电流的原则。在本文中，我们展示了不同的周期调制技术，并提出了相应的电磁兼容性优化方法。提出了一种系统的方法来优化有限长度调制序列。我们准备了性能指标的数学表达式作为优化算法的基础。不同的波形生成方法的性能进行了验证，使用DC-DC转换器的例子。指出优化波形是功率谱整形的有力工具
Hybrid systems are known to be potential sources of electromagnetic interference due to their principle of recurrently switching voltages and currents. In this paper, we demonstrate different periodic modulation techniques and propose corresponding electromagnetic compatibility optimization methods. A systematic way to optimize finite length modulation sequences is proposed. We prepare mathematical expressions of performance indexes as a base for optimization algorithms. The performance of the different waveform generation methods is verified using a dc-dc converter example. It points out that the optimized waveforms are a powerful tool to shape the power spectrum
