Inside servers, DC-DC converters play a crucial role in stepping down voltages from an input range of 40V to 60V to 12V, with each converter delivering power levels of several kilowatts and currents exceeding hundreds of amperes. These converters must not only provide stable output voltage but also achieve conversion efficiencies exceeding 98%. Components such as memory, CPUs, and ASICs often require voltages lower than 12V, necessitating additional DC-DC conversion. In AI servers, GPU Vcore power modules must step down to less than 1V while supplying output currents that can reach thousands of amperes. Chroma's power testing solutions include DC power supplies and high-performance electronic loads that cover a wide range of DC converter specifications. With high-precision measurement capabilities, these solutions meet the demands of efficient and accurate testing. Additionally, instruments can be flexibly configured into the Chroma 8000 Automated Test System to fully validate the specifications and performance of DC converters—ideal for both R&D verification and high-efficiency production line testing.
