In what direction will switching power supplies develop in the next five to ten years?

With the development of 5G facilities, new energy vehicles, and smart cities, the demand for innovative power supply applications is increasing. Here are a few cases:

(1) 5G facilities require high power density power supply design

The 5G communication network has put forward new requirements for the data processing and wireless communication capabilities of base station facilities, which has led to a substantial increase in base station power. At the same time, due to the limitations of the computer room space, the communication/server power supply design must achieve higher efficiency in a limited space. power density. Silicon, silicon carbide and gallium nitride are currently popular materials.

(2) EV drive power supply changes

The new energy automobile industry is accelerating its development driven by the continuous maturation of technology. Currently, DC charging piles and AC OBC (On Board Charger) are the two mainstream methods. The system output power of DC charging piles is gradually moving from the current mainstream 20kW to 50kW, 120kW or even 350kW. The industry is in urgent need of charging solutions with lower system cost (cost/watt), higher energy efficiency and higher power density.

(3) Smart cities accelerate IoT

Smart cities, as a key component of IoT, can realize functions such as urban resource allocation and traffic optimization management. Current smart indoor lighting requires efficient power management, agile sensing, cloud services and connected security.

5G, IoT and new energy vehicles are currently the most popular power supply application fields, and Shenzhen UniHP Technology Co., Ltd. has provided relevant product solutions in these fields.
