High frequency switching power supplies, with their core advantages of high efficiency, high power density, miniaturization, and modularity, have deeply penetrated into multiple key industries and become the core power supply unit of modern power electronics systems. Its main application industries are as follows:

Communication and Information Infrastructure

As the "energy cornerstone" of communication networks, high-frequency switching power supplies are widely used in:

5G base station: provides -48V DC power supply for BBU, RRU and other devices, supports N+1 redundancy design and hot swappable maintenance, and meets high-density, all-weather operation requirements

Data center: deployed in server cabinets and UPS systems, adopting a modular parallel architecture with a conversion efficiency of over 90%, supporting the low-carbon operation of the "East Data West Computing" project

Network equipment: provides stable DC power supply for routers, switches, and optical transmission equipment, ensuring the continuity and low noise characteristics of data transmission

Industrial Automation and High end Manufacturing

In the field of industrial control, high-frequency switching power supply is a key support for achieving precision control and intelligent manufacturing:

Industrial PLC and servo system: Provides 24V/12V DC power supply for Siemens, Huichuan and other brand controllers, with strong anti-interference ability and a working temperature range of -40 ℃ to+85 ℃

Industrial robots: Drive the motion unit of the robotic arm, support high dynamic response and precise current control

Electroplating and electrolysis industry: high-power high-frequency switching power supply (such as 3000A/12V) is used for surface treatment such as anodizing, galvanizing, nickel plating, etc., with voltage/current accuracy<± 0.5%, supporting PWM modulation and 485 communication

New energy and energy storage system

In the context of energy transition, high-frequency switching power supplies have become an important interface for the new energy system

Electric vehicle charging station: as the core of AC-DC conversion, it achieves efficient and fast charging (supporting power levels of 30kW~480kW)

Energy storage power station: working in conjunction with lithium battery packs to achieve peak shaving and valley filling, grid frequency regulation, and improve energy utilization efficiency

Photovoltaic inverter system: used for DC side boost and MPPT control to improve power generation conversion rate

Medical and Life Science Equipment

Medical grade high-frequency switching power supplies must meet the strict IEC 60601 safety standard:

Imaging diagnostic equipment: provides tens of thousands of volts of high-voltage power supply for CT and X-ray machines to ensure imaging accuracy

Life support system: provides low ripple, electrically isolated power supply for ventilators, monitors, and infusion pumps to ensure patient safety

Portable medical equipment: integrated into handheld ultrasound devices and home blood glucose meters, supporting battery/mains dual-mode power supply

Consumer Electronics and General Weak Current

As the application field closest to daily life:

Mobile phone/laptop charger: using GaN/SiC devices to achieve ultra small size and efficiency of over 95%

Smart terminal power supply: providing stable low-voltage DC power for smart home gateways, security cameras, and IoT terminals

Rail Transit and Special Applications

Play a critical role in high reliability scenarios:

Rail Transit Communication System: Provides AC/DC dual power supply for 5G private network equipment and signal systems, in compliance with MIL-STD series military standards

Onboard and avionics: 28V DC power supply is used for avionics systems, with a switching frequency of 250kHz and ripple control within 50mV

Special power supply: such as 400Hz input airborne power supply, explosion-proof power supply, etc., to meet the special environmental needs of military industry, ships, oil fields, etc
