But inside a data center, nearly all the equipment runs on direct current (DC). Before it reaches the servers, the power must pass through a host of devices like transformers, converters and controllers, stepping through multiple stages to change the current or the voltage.<\/p>\n\n\n\n<p>Along the way, each conversion leaks energy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-devices-guide-the-electricity-journey\"><strong>Devices guide the electricity journey<\/strong><\/h3>\n\n\n\n<figure class=\"alignleft uwm-c-img--left\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/uwm.edu\/engineering\/wp-content\/uploads\/sites\/537\/2025\/10\/AI.Guo_.Knapoj-1.jpg\" alt=\"Two men at a lab bench looking at the camera.

Guo (front) holds a component of semiconductor testing, while Chaimanekorn displays the paralleled power electronics converters which increase the output current and power. <\/figcaption><\/figure>\n\n\n\n<p>Data centers are raising their DC voltage to pack more power into the same space and boost efficiency. This requires redesigning equipment, collectively called power electronics, needed to shepherd the flow of electricity in ways that achieve that.<\/p>\n\n\n\n<p>Researchers feed AI models vast amounts of electrical data, from voltage and current to frequency patterns. From the data, AI develops a deep understanding of how these systems behave. That knowledge informs smarter designs for converters and other crucial components that waste less energy from the start.<\/p>\n\n\n\n<p>And that&#8217;s only the beginning. After engineers model the system, then AI can figure out the most efficient playbook.<\/p>\n\n\n\n<p>Think of AI as a conductor, orchestrating \u201csmart\u201d components that generate, route, and control power. It can even take on tricky jobs like fault detection and managing renewables.<\/p>\n\n\n\n<p>\u201cEach time you train the model, you\u2019re asking a slightly different question,\u201d Guo said. \u201cIt&#8217;s a process that strengthens the model.
