Pulse Transformers for PLC
Tech Notes
Driven by environmental concerns and the pursuit of sustainability, electric vehicles (xEVs) are rapidly gaining popularity worldwide. Europe is focusing on CCS (Combined Charging System), while North America is adopting NACS (North American Charging Standard), leading to a rapid expansion of charging infrastructure. These standards rely on PLC (Power Line Communication) for charging control, making high-quality pulse transformers essential. This article highlights the advantages of TDK’s AMT45S pulse transformer, designed for the latest charging standards.
TDK Product Features
Pulse transformers for PLC are used as transformers for transmitting pulse signals in the charging control circuit between the vehicle and the charger in xEV charging standards such as CCS (Combined Charging System) and NACS (North American Charging Standard). In the charging control circuit, these transformers provide functions such as circuit isolation, noise suppression, and signal waveform preservation. While conventional toroidal types mainly use manual winding methods, TDK’s pulse transformers for PLC achieve both miniaturization and stable characteristics through proprietary automatic winding technology.
