The future development direction of chargers and adapters


In any industry, if you do not want to be eliminated by the market, you must keep up with the industry's development direction. The former industry giant Nokia was directly slashed because it failed to keep up with the development of smart phones. So where is the development direction of Switching Power Supply? Charger manufacturers believe that the future development trend of Power Supply is green, miniaturized, digital, and integrated.


Green: Green energy saving is the general trend. At present, Europe and the United States have adopted six-level energy efficiency standards, and the future requirements for power consumption will be higher and higher.

Miniaturization: The miniaturization and weight reduction of power supplies are particularly important for mobile and telecommunication power supply products, and we are now able to see this trend in increasingly smaller cell phone chargers. Therefore, improving the power density and power conversion efficiency of switching power supplies to make them smaller and lighter will be the goal that power supply manufacturers continue to pursue.

Digitalization: The digital power supply combines the high efficiency of the power supply with the intelligent control of the digital chip, and uses appropriate algorithms to adjust the voltage and current. Compared with the analog power supply, the digital power supply can perform accurate digital correction on the current detection error, and the voltage detection is more accurate, which can realize a fast and flexible control design.

Integration: In order to improve the reliability of the system, it has become a trend for complete machine manufacturers and component manufacturers to develop "user-specific" power modules. That is, almost all hardware of a complete machine is installed in a module in the form of a chip, so that a large number of components are no longer connected by traditional leads, and parasitic parameters are minimized, thereby reducing power components and power The electrical stress on the device is reduced to a minimum, so as to improve the reliability of system equipment.

Going green, miniaturization, digitization, and integration are constantly advancing, leading the development of the entire power supply industry, and bringing more efficient and safer power supply products to society is one of the current development directions of battery manufacturers.
