Research on the design of smart PD fast charger

The development direction of intelligent PD fast charging technology: high-power transmission, multi-device charging, sustainable energy and green charging, data and charging integration, safety and standardization, intelligent and adaptive charging, etc. These features will provide users with a faster, more efficient, smarter, and more sustainable charging experience, and promote the widespread application and development of USB PD technology in the future. In this paper, the intelligent PD fast charging design is combined with AC-DC PWM integrated circuit chip, DC-DC SR synchronous rectifier chip, quasi-resonant technology, fast charging protocol chip and other technologies to design a 65W intelligent PD fast charger.
