APEC 2024: Power to the data center
Data centers power the world, or does the world power data centers? According to one report, datacenters currently consume 2% of the world’s electricity and that could increase to 8% by 2030. Much of that electricity arrives at the load as low voltage, high current. For example, a single IC, processor, graphics processor, AI chip, […]
