he Mode 4 charging system converts AC from the grid to DC and charges the car without using an inverter. This mode is defined by IEC 61851-23 standard, integrates the functions like converting AC/DC power, protecting people from electric shock, and a payment.
J&D Electronics, by itself, has developed and produced the devices that Mode 4 consists of for the safety and efficiency of Mode 4. Based on that, EV DC fast chargers and DC meters have been developed, and through this, it is possible to develop an optimized CT to improve safety and efficiency by being integrated with these devices.
To be more specific, J&D JDTN series CTs, the DC tolerance CTs suitable for Mode 4 by adding a DC immunity function, so that it is not affected by DC when measuring 3-phase AC power, are released. The IACT series CTs are also released to be able to apply to High efficiency AC -> DC Power modules. In addition, the IDCS series was released so that it could be used for Revenue-grade DC meters.
