Isolated AC–DC Converters for High-Density USB-PD Adapters: A Comparative Review of Topologies and Future Trends
The transition of the USB Power Delivery (USB-PD) standard from fixed 5–20 V profiles to the dynamic extended power range (EPR) of up to 48 V and 240 W has redefined the constraints of isolated AC–DC conversion for high-density adapters and chargers. Delivering high efficiency simultaneously at low (5 V) and high (28–4...
