Existing filter design methods for grid-tied power converters either focus on grid current harmonic suppression or electromagnetic interference (EMI) noise attenuation. This article proposes a simulation-based, multifunctional filter design method, which can simultaneously handle multiple objectives, including minimizing grid current total harmonic distortion (THD), conductive EMI noise, ground leakage current, touch current, filter weight, and so on. By modeling equivalent filter circuit and simulating in the Powersim (PSIM) software, the approach avoids traditional complicated circuit analysis and mathematical computation. In addition, unlike most existing filter design approaches that only focus on one specific application or converter topology, this filter design method is a generalized approach and can also be used for universal converters that have variable applications. To demonstrate this feature, the filter design method is applied to a recently proposed series-capacitive-link universal converter. Experimental results verify the effectiveness of the proposed method.

通用转换器的基于仿真的多功能差分模式和共模滤波器设计方法

并网功率转换器的现有滤波器设计方法要么着重于电网电流谐波抑制,要么着重于电磁干扰(EMI)噪声衰减。本文提出了一种基于仿真的多功能滤波器设计方法,该方法可以同时处理多个目标,包括最小化电网电流总谐波失真(THD),导电EMI噪声,接地泄漏电流,接触电流,滤波器重量等。通过对等效滤波器电路建模并在Powersim(PSIM)软件中进行仿真,该方法避免了传统的复杂电路分析和数学计算。此外,与大多数现有的滤波器设计方法仅专注于一种特定的应用或转换器拓扑不同,这种滤波器设计方法是一种通用方法,也可用于具有可变应用的通用转换器。为了演示该功能,将滤波器设计方法应用于最近提出的串联电容链接通用转换器。实验结果证明了该方法的有效性。
