Overview

The TPSF12C3-Q1 evaluation module (EVM) is designed to evaluate the performance of the TPSF12C3-Q1. The solution improves the common-mode (CM) electromagnetic interference (EMI) filter in three-phase AC power systems. The TPSF12C3-Q1 IC provides a low-impedance path for CM noise in the frequency range of interest for EMI measurement and helps to meet prescribed limits for EMI standards.

Features
  • Active EMI filter (AEF) IC enables up to 25dB of common-mode EMI reduction
  • Over 50% reduction in the size and weight of the CM chokes of the AC line filter
  • Suitable for 3-phase AC power systems
  • Voltage range from 8 V to 16 V, nominally 12 V

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.
