Now server,AIEach rack in edge computing and data centers provides an average of 3kW-5kW power application forCPU andGPUPower supply to ensure high-efficiency work, traditional use12VOutput power architecture. Responding to artificial intelligence and processorCPU,GPUorNPUAs the demand for high power continues to grow, the power requirements of servers are also increasing. The bigger it gets, the more demanding the design environment becomes. The new generation of AI The total power demand has reached 10kW. Therefore, the current power supplyDC/DC design will The circuit is divided into two levels of design: Level 1 Convert48V12V/6V; No.2level is12VTransfer1.8V/1.2V/1.0V/0.8Vfor terminal equipment applications.

Comparison between modular power supplies and discrete devices:

• Level 1 Most of the power supply modules have transformers with a planner design, and our company often provides customized iron cores to match.
• The second-level power module inductor is designed in two types: Assembly and Molding: the assembled type can be made of a single material or a combination of different materials. To achieve the best results, such as adapting to switching frequency, wide temperature range application, reducing product size, etc.; and the one-piece form is the process chosen by new level 2 power modules recently, because the one-piece forming process brings higher reliability It has greater flexibility and smaller design volume, and the selection of individual inductor components is more consistent.
