Power Modules

Core electronic components that convert input electrical energy into stable voltage/current required by devices. Common types include AC-DC, DC-DC, and DC-AC converters. Their core function is to process power through circuits such as rectification, filtering, and voltage regulation, eliminating grid fluctuations and noise interference, and providing clean power for communication equipment, industrial control systems, medical devices, and consumer electronics. Modern power modules employ high-frequency switching technology, achieving conversion efficiency of over 95%, and integrate multiple protection mechanisms such as overvoltage, overcurrent, and short-circuit protection. They can operate in a wide temperature range from -40°C to +85°C. The modular design significantly simplifies system integration, supports plug-and-play, and with smart control interfaces, enables remote monitoring and dynamic voltage adjustment. They are widely used in new energy, 5G base stations, and IoT applications.
