USB-IF has introduced the USB Power Delivery EPR certification program, which defines a transfer mode using voltages higher than 20 volts (28V, 36V, and 48V). This certification mandates that products operating in EPR mode must maintain constant monitoring of their EPR partners. Additionally, to prevent electric arc-related damage to USB-C connectors, the EPR program incorporates three types of Adjustable Voltage Supply (AVS) for battery-operated devices. In Standard Power Range mode, while Programmable Power Supply (PPS) is optional, the requirement is for AVS. This setup enhances the efficiency of charging for battery-operated devices.
