tpsf12c3 是一款有源滤波器 ic，旨在降低 三相交流电源系统中的共模 (cm) 电磁干扰 (emi)。
配置了电压检测和电流注入 (vsci) 的有源 emi 滤波器 (aef) 使用电容倍增器电路来模拟传统无源滤波器设计中的 y 电容器。该器件使用一组检测电容器来检测每条电源线上的高频噪声，并使用注入电容器将降噪电流注入电源线。有效的有源电容由电路增益和注入电容设置。aef 检测和注入阻抗使用相对较低的电容值，组件尺寸较小。该器件包括集成滤波、补偿和保护电路，以及使能输入。
tpsf12c3 在 emi 测量所需频率范围内提供了极低的 cm 噪声阻抗路径。在指定频率范围（例如 150khz 至 3mhz）的下限降低高达 30db 的 cm 噪声，可显著降低 cm 滤波器实施方案的尺寸、重量和成本。

tpsf12c1/3 mathcad file
this mathcad worksheet is offered to predict the stability of a voltage-sense, current-inject active emi filter (aef) circuit, in particular with respect to ti's tpsf12c1/3/-q1 family of aef ics, and to assist with component selection. the model is inclusive of most parasitc effects and can be used as a quick check of the loop gain and insertion loss prior to simulation, bench measurement and fine tuning.
the worksheet functions for single- and 3-phase ac systems and facilitates two ways of entering the cm choke parameters:
1. using an equivalent circuit model with (a) resistive and capacitive parasitics – suitable for ferrite-core chokes; (b) a ladder network of three parallel rl circuits -- suitable for nanocrystalline chokes
2. using measured impedance data (magnitude and phase).
the worksheet is ideal for knowledge capture, unit-aware calculation reuse and for engineering collaboration amongst design, systems & application engineers.
