TPSF12C1DYYR General Description

The TPSF12C1 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 provides a very low impedance path for CM noise in the frequency range of interest for EMI measurement. Enabling up to 30 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.
