USB Power Delivery EPR Test

USB Power Delivery (PD) Protocol

USB Power Delivery (PD) is a specification that allows devices to charge over a USB connection at higher power. Using a standard USB type C cable, it can handle up to 60W, and using an EMCA cable, it may go up to 100W ~ 240W. It operates by the power source and sink device negotiating a power contract using the USB PD protocol. In the slides, i will go through the PD protocol in details.
