3 Description
The TPSF12C1-Q1 is an active filter IC designed
to reduce common-mode (CM) electromagnetic
interference (EMI) in single-phase AC power systems.
The active EMI filter (AEF) configured with voltage
sense and current inject (VSCI) uses a capacitive
multiplier circuit to emulate the Y-capacitors in a
conventional passive filter design. The device senses
the high-frequency noise on each power line using a
set of sense capacitors and injects noise-canceling
currents back into the power lines using an injection
capacitor. The effective active capacitance is set by
the circuit gain and the injection capacitance. The
AEF sensing and injection impedances use relatively
low capacitance values with small component
footprints. The device includes integrated filtering,
compensation and protection circuitry, and an enable
input.
The TPSF12C1-Q1 provides a very low impedance
path for CM noise in the frequency range of interest
for EMI measurement. Enabling up to 25 dB of
CM noise reduction at the lower end of specified
frequency ranges (for example, 150 kHz to 3 MHz)
significantly reduces the size, weight and cost of the
CM filter implementation.
