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.
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.
