Wideband Power Line Communication (PLC) SMT Transformers

PLC transformers from Pulse Electronics, a YAGEO Company, are traditionally associated with home networking and are used primarily for extending the reach of LAN connections from the central router or modem in the home office without the need to add new wiring to the building. By removing the deployment of Cat5 cable to every room and at sites where a wireless solution could be problematic, the use of the mains power ring to support data signals is quick and easy with proven reliability. This now makes PLC-based communications links ideal for off-grid, green energy backup storage systems and automotive charging points for electric vehicles.

The Pulse Electronics’, a YAGEO Company, PLC series in SMD package offers high isolation up to 4 kV and various insulation classes from functional to reinforced across the hybrid TX/RX:LINE (1:1:1) turns ratio. These match with the leading broadband PLC chipsets, operating in the wideband frequency range of 3 MHz to 30 MHz, from market-leading PLC IC and transceiver vendors.

The BM6150NL is specifically matched to the Maxim 2980/2986 chipset pairing, while the BX6152/53NL and BX6158NL are more generic and can provide a different option for Qualcomm's GreenPHY – QCA700x, Intellon's INT5500/INT1200, and STMicro's ST2100 IC suites.

There are also designs that are specific for automotive use. The BM6154NL and BM6155NL support supplementary isolation per IEC/UL62368 (working voltage 250 V_RMS) for the STMicro PLC transceiver STM2001 and can be made in an IATF certified factory for mission critical drivetrain applications and the BMU6201NL, which is qualified for Qualcomm QCA700x chipsets for external charger links between the OBC and charger unit, detecting V2G faults and cutting off the power.
