Biscuit PD fast charging charger, ultra-thin design, eliminating input filter capacitor, adopting nonpolar capacitor and combining APFC architecture scheme; However, as early as 2065438+June 2009, our company has started the design of this architecture scheme, with the purpose of canceling the input filter capacitor, making the product ultra-thin and miniaturized, and at the same time improving the PF value, which is more energy-saving and environmentally friendly;
At the same time, applied for a patent; Patent No.20 1920982486 1 A charger based on APFC.
