Hi Harisyam,
Thank you for recommending PMP23338 and PMP23475.
For our 5.5 kW telecom rectifier, we would like to compare these two PFC approaches:
-
TI’s totem-pole PFC approach, particularly the two-phase interleaved approach in PMP23475, adapted for 5.5 kW.
-
An NXP TEA2209T-controlled MOSFET active rectifier followed by a two-phase CCM interleaved boost PFC, using TIDM-02010 firmware adapted to an F28002x controller.
Our product needs to meet FCC Part 15 Class B conducted and radiated emissions limits, as well as the applicable NEBS requirements.
Could you please advise on the following?
-
Has either TI reference design undergone conducted/radiated EMI testing against Class B limits or relevant NEBS EMC requirements? Are test reports and EMI filter details available?
-
Under comparable input voltage, power, enclosure, grounding, and filtering conditions, which approach would generally be easier to bring into Class B compliance? We are particularly interested in common-mode noise, switching-edge effects, and AC zero-crossing behavior.
-
Which approach would you expect to achieve higher PFC-stage efficiency at 230 Vac and 5.5 kW, particularly at half load and full load? Since the TEA2209T approach already replaces the diode bridge with MOSFETs, what additional efficiency benefit should we realistically expect from the totem-pole approach?
We understand that compliance depends on the complete product design, PCB layout, filtering, and enclosure, rather than the topology alone. We would appreciate any measured results or practical design guidance for this comparison.
Best regards,
Zhen
