TPSF12C1-Q1 是一款有源滤波器 IC，旨在降低 单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。
TPSF12C1-Q1 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。

Welcome to the TPSF12C1/-Q1 and TPSF12C3/-Q1 quickstart design tool. This standalone tool facilitates and assists the power supply engineer with the design of an active EMI filter (AEF) circuit based on this family of common-mode AEF ICs. As such, the user can expeditiously arrive at an optimized design to meet the application requirements.
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.
