Communication between charging stations and electric vehicles via an interface compliant with EN ISO 15118 is a fundamental requirement for the public charging infrastructure. Würth Elektronik now offers the WE-PLC product series of high-quality SMT transformers for Power Line Communication (PLC).
The new Würth Elektronik PLC transformers are ideal for galvanic isolation of the PLC system from the power supply. They are designed for data signals between 500 kHz and 30 MHz and reliably isolate the low-voltage range from the high-voltage range.
More precise data transmission
The WE-PLC product series offers an exceptionally high test voltage of 4500 VRMS for transformers of this package size (13.6 × 9.9 mm footprint). Thanks to their high-quality design, they offer significantly lower leakage inductance (max. 0.2 µH) than competing products. The components ensure good magnetic coupling for precise data transmission.
The WE-PLC 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 250 VAC.
The PLC transformers are now available from stock without a minimum order quantity. Free samples are available for developers.
