2.1 EVM Description

The TPSF12C1QEVM, a daughter-card design that attaches to an existing passive EMI filter circuit in a single-phase AC power system, showcases the CM EMI performance improvement or size reduction achievable with the TPSF12C1, a single-phase power-supply filter IC.

The EVM can be used for evaluation and for system development of a single-phase EMI filter circuit and application. The AEF circuit effectively replaces the two Y-capacitors normally placed between the CM chokes (and tied to chassis ground) in a conventional two-stage, fourth-order passive CM filter design. The design uses a recommended PCB layout to minimize the overall noise signature and required board area.

Note: The damping and compensation component values included with this EVM can require modification if the passive filter components (the CM chokes in particular) are changed. Refer to the TPSF12C1 Standalone Active EMI Filter for Common-mode Noise Mitigation in Three-Phase AC Power Systems data sheet and TPSF12C1 quickstart calculator for additional guidance pertaining to AEF circuit operation, loop gain and stability analysis, passive component selection, and expected common-mode EMI performance.
