German electronics manufacturer Würth Elektronik is helping maintain communications between charging stations and electric vehicles via an interface compliant with EN ISO 15118.

This is a fundamental requirement for the public charging infrastructure. Würth now offers the WE-PLC product series of SMT transformers for power line communication (PLC).

The PLC transformers are for galvanic isolation of the PLC system from the power supply. They are designed for data signals between 500kHz and 30MHz and reliably isolate the low-voltage range from the high-voltage range.

The WE-PLC (www.we-online.com/en/components/products/WE-PLC) series has a high test voltage of 4.5kV RMS for transformers of this package size with a 13.6 by 9.9mm footprint. They are said to offer lower leakage inductance (up to 0.2µH) than competing products. The components ensure good magnetic coupling for precise data transmission.

The transformers are available with turns ratios of 1:1:1 and 1:4:3 for EV charging and AC interfaces for grid communication. The operating voltage is up to 250V AC.

The PLC transformers are now available from stock without a minimum order quantity. Free samples are available for developers.
