TPSF12CX-MATHCAD
概覽
此 Mathcad 檔案的用途是預測電壓感測電流注入 AEF 電路的穩定性,特別是 TI 的共模 (CM) AEF IC TPSF12C1/3/-Q1 系列的穩定性,並協助元件選擇。此模型包含大多數寄生效應,可在模擬、基準測量和微調前用於快速檢查迴路增益和插入損耗。此工作表適用於單相和三相 AC 系統,並提供兩種輸入 CM 扼流器參數的方法:
- 使用 CM 扼流器行爲模型搭配
- 電阻與電容寄生 – 適用於鐵氧體磁芯扼流器
- 由三個並行 RL 電路組成的梯形網路 – 適用於奈米晶扼流器
- 使用測量的阻抗數據 (幅度和相位)
特點
- 檢查 CM 扼流器阻抗與頻率行爲的比較
- 選擇適用於補償與阻尼網路的零組件
- 根據被動濾波器零組件最佳化迴路增益以獲得穩定性
- 啟用和停用 AEF 時,檢查濾波器衰減性能

版本資訊
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.
