The TPSF12C1EVM-FILTER single-phase active EMI complete filter evaluation module (EVM) is designed to conveniently evaluate the performance of the TPSF12C1 active filter IC. The EVM helps to improve the common-mode (CM) electromagnetic interference (EMI) signature in single-phase AC power systems by amplification of the effective Y-capacitance value. A higher effective Y-capacitance enables a reduction in CM choke size, weight and cost.
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.
