Turns Ratio
Depending on the application, transformers with different turns ratios are required. A turns ratio of 1:1:1 is used for the PLC interface in e-mobility applications on the charging station side (EVSE). For AC grid communication interfaces, such as in smart grid, IoT or smart home applications, a transformer with a turns ratio of 1:4:3, for example, couples the modem signal to the grid.
From mobile charging cables (ICCPD) to wallboxes for the home and public charging stations (HPC) - Würth Elektronik develops and manufactures electronic and electromechanical components for a wide range of these applications.
