High-performance MCU creates 3.5kW DC charging pile solution – YMIN capacitors provide reliable hardware guarantee

In November, GigaDevice launched a new 3.5kW DC charging pile solution based on the GD32G5 series high-performance MCU. The system uses a single MCU to control the front-stage totem pole PFC and the rear-stage full-bridge LLC two-stage topology, achieving a peak efficiency of 96.2% and a THD as low as 2.7%, meeting the high efficiency and stability requirements of new energy charging piles. With the upgrade of the charging pile solution, the performance requirements for internal components have become more stringent. After in-depth communication with GigaDevice and a detailed understanding of its specific needs, YMIN successfully developed high-performance capacitors that meet the requirements of the 3.5kW DC charging pile solution and has been successfully applied. With excellent quality, it helps to create a more efficient and reliable charging system.
