TPSF12C1-Q1 单相有源 EMI 滤波器评估模块
TPSF12C1QEVM
概述
TPSF12C1-Q1 评估模块 (EVM) 专门设计用于方便地评估 TPSF12C1-Q1 有源滤波器 IC 的性能。该解决方案改善了单相交流和三线直流电源系统中的共模 (CM) 电磁干扰 (EMI) 特征。TPSF12C1-Q1 IC 在 EMI 测量相关的频率范围内为 CM 噪声提供低阻抗路径,可满足 EMI 标准(如 CISPR 11、CISPR 25 和 CISPR 32)规定限制。
特性
- 有源 EMI 滤波器 (AEF) IC 可将共模 EMI 噪声降低高达 25dB
- 可将交流线路滤波器 CM 扼流圈的尺寸和重量缩减 50%
- 适用于单相交流或三线直流系统
- 8V 至 16V 的宽电源电压范围(额定电压 12V)
- 可轻松连接到两个检测电容器和一个注入电容器

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.
