控制信号变化对PWM变换器谐波的作用模型
Modelling the Effect of Control Signal Variation on the Generation of Harmonics in PWM Converters
摘要
在频域内使用频率耦合矩阵(FCMs),用建模方法描述了控制信号变化对PWM变换器谐波的影响。该方法是建立在对变换器开关函数严格的数学分析基础上的,并在频域内产生了,一个完整的分析式。本文提供了这种建模方法得到的结果并用时域内的仿真数据进行了校验。
The effects of control signal variation on the generation of harmonics in PWM converters are described using a modelling approach in the frequency domain using frequency coupling matrices （FCMs）. The approach is based on rigorous mathematical analysis of the switching function and yields a full analytical solution of the converter in the frequency domain. Results from this modelling approach are presented andvalidated against time domain data analysis.
