Data Center Power: What are AC and DC Power in Data Centers?

The fewer conversions the power supply undergoes, the lower the losses and the less heat generated. Greater efficiency leads to lower costs, both in capital and O&M. In this sense, a DC power data center tends to be more energy-efficient as a AC power data center involves more AC to DC conversions. Pros & Cons
