EVM User's Guide: TPSF12C3QEVM
Active EMI Filter Evaluation Module for Three-Phase AC
Power Systems
Description
The
TPSF12C3QEVM
evaluation module (EVM) is
specifically designed to validate the performance of
the
TPSF12C3
power-supply filter IC. The active EMI
filter (AEF) helps to improve the common-mode (CM)
electromagnetic interference (EMI) signature in three-
phase AC power systems by amplification of the
effective Y-capacitance value.
Get Started
1. Order the
TPSF12C3QEVM
2. Study this EVM user's guide and
3. Use the TPSF12C3
quickstart calculator
with EMI filter design and component selection
4. Prior to connecting the power stage,
active filter circuit with a low-voltage signal source
5. Connect the filter to an AC-input power stage and
verify the INJ (pin 13) voltage swing is within limits
6. Measure the total (DM and CM) EMI signature
and use a splitter to isolate the CM contribution
Features
Improved CM
EMI performance
with three-phase AC input
– Helps to meet EMI standards, such as CISPR
11, 25 or 32
– Voltage-sense, current-inject AEF topology
presents low shunt impedance to ground
Up to 30 dB reduction in the CM EMI
signature from 100 kHz to 3 MHz
