Behind the explosive growth in computing power demands, such as AI large model training and supercomputing centers, traditional power supply solutions are facing dual challenges of efficiency and stability.

IVS showcased its full range of high-performance power supply solutions for the first time at the Electronica China in Shanghai, directly addressing the pain points of AI + computing power efficiency, and assisting in the core power supply upgrades of data centers, servers, switches, desktops, communications, and other fields. The exhibition site attracted a large number of professional visitors and industry colleagues to stop by and communicate.
