AI生成コンテンツ: USB-C Power Delivery 3.1 Extended Power Range (EPR) enables up to 240W power delivery with voltages up to 48V and currents up to 5A, supporting fast and efficient charging for high-power devices such as laptops, portable power stations, and large displays. The system integrates a GaN-based high-efficiency AC/DC adapter, a bi-directional 48V charger, and a Battery Management System (BMS) with fuel-gauge firmware. Key design challenges include high-efficiency power conversion, voltage/current flexibility, bidirectional power flow, safety, and modular scalability. The solution provides reference designs, BOM, schematics, Gerber files, and firmware to accelerate product development and ensure compliance with regulatory standards.
