Active EMI Filter Evaluation Module for Single-Phase AC Power Systems

Description

The TPSF12C1EVM-FILTER evaluation module (EVM) is specifically designed to validate the performance of the TPSF12C1 power-supply filter IC. The active EMI filter (AEF) 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.

Get Started

  1. Order the TPSF12C1EVM-FILTER EVM
  2. Study this EVM user's guide and PCB layout files
  3. Use the TPSF12C1 quickstart calculator to assist with EMI filter design and component selection
  4. Prior to connecting the power stage, test the active filter circuit with a low-voltage signal source
  5. Connect the filter to an AC-input power stage and verify the INJ voltage swing is within limits
  6. Measure the total (DM and CM) EMI signature and use a splitter to isolate the CM contribution
