Overview

The TPSF12C1-Q1 evaluation module (EVM) is specifically designed to conveniently evaluate the performance of the TPSF12C1-Q1 active filter IC. The solution improves the common-mode (CM) electromagnetic interference (EMI) signature in single-phase AC and 3-wire DC power systems. The TPSF12C1-Q1 IC provides a low impedance path for CM noise in the frequency range of interest for EMI measurement and meets prescribed limits for EMI standards, such as CISPR 11, CISPR 25 and CISPR 32.

Features
  • Active EMI filter (AEF) IC enables up to 25dB of common-mode EMI reduction
  • 50% reduction in the size and weight of the CM chokes of the AC line filter
  • Suitable for single-phase AC or 3-wire DC systems
  • Wide supply voltage range of 8 V to 16 V, nominally 12 V
  • Easy connection to two sense capacitors and an injection capacitor

Release Infomation

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.
