  • TPSF12C1EVM-FILTER: A tool for simple evaluation of the TPSF12C1EVM-FILTER

    Part Number: TPSF12C1EVM-FILTER Tool/software: Hi, I am preparing equipment to demonstrate the TPSF12C1EVM-FILTER. Can I perform the evaluation if I have the following equipment? ・AC power supply ・DC power supply (for VDD supply) ・Oscilloscope ・EMI test…

  • TPSF12C1EVM-FILTER: Modifying Active EMI Filter To Work With 19kHz Switching Frequencies.

    Part Number: TPSF12C1EVM-FILTER Other Parts Discussed in Thread: TPSF12C1 , TPSF12C3 Tool/software: Hello Tech Gurus, We are building next gen UPS (115V in and 115V out) and were looking in to shrinking the size of the EMI filters. We came across this…

  • TPSF12C1EVM-FILTER: Not capable of handling multiple frequencies?

    TI Thinks Resolved
    Part Number: TPSF12C1EVM-FILTER Hello, We have been trying to make the TPSF12C1EVM active filter work for filtering in our product (motor control), but we have found the results to be extremly disapointing. When connected to the bench and an osciloscope…

  • TPSF12C1EVM-FILTER: One CM choke/Capacitor/DC input/ Noise reductio

    TI Thinks Resolved
    Part Number: TPSF12C1EVM-FILTER ① can the CM chokes be used in two stages for ACF performance? In the data sheet, the AEF is sandwiched between the two-stage CM choke configuration. Since many of our power supply filter configurations have a single-stage…

  • TPSF12C1-Q1: Availability of a LTspice compatible model

    Part Number: TPSF12C1-Q1 Other Parts Discussed in Thread: TPSF12C1EVM-FILTER , Tool/software: Hello, I'm trying to simulate the circuit of the TPSF12C1EVM-FILTER on LTspice. For this I need to import the model of the TPSF12C1-Q1 in the software, but the…

  • RE: TPSF12C1: Origin of the choke models in PSpice

    Resolved
    Hi Matthias, The model is based on the impedance characteristic (magnitude and phase) for a given CM choke. The impedance measurement is performed first (or use the vendor's measurements) and then the choke behavioral model is derived. I'm not sure…

  • RE: TPSF12C1-Q1: TPSF12C1 PSpice model : Confirmation of AEF operation in simulation.

    2. It is understood that AEF outputs the reverse phase component of the common mode noise at the INJ Stage. However, V(RINJ) and V(Rsense1, Rsense2) simulations do not show an opposite phase component, is this correct? 3. when verified on the actual device…

  • TPSF12C1-Q1: Insertion loss

    Resolved
    Part Number: TPSF12C1-Q1 Other Parts Discussed in Thread: TPSF12C1EVM-FILTER , TPSF12C1 Hello, I would like to know what does insertion loss mean in terms of the filter performance. Also how can it be measured using the TPSF12C1EVM-Filter module? Can you…

  • RE: TPSF12C1: It is not working properly, The output waveform of the unconnected noise source is not 6V DC

    Here is the link to the TPSF12C1 filter EVM (the order link should be live later today): https://www.ti.com/tool/TPSF12C1EVM-FILTER

  • RE: TPSF12C1QEVM: No change on the noise

    By the way, we just released a complete filter board EVM with AEF - see here www.ti.com/tool/tpsf12c1evm-filter . The user's guide also has additional information for test setup, etc.
