How to Provide Eff ective Power Management for AI Datacentres


The rise of artifi cial intelligence (AI) and machine learning (ML) has created unprecedented power demands


By Kenton Wiliston, DigiKey T


he next generation of data centres faces significant challenges in power management, efficiency and reliability. Traditional power solutions often struggle to meet these demands at the level of individual components and overall data centre infrastructure management


(DCIM). Advanced power components and integrated monitoring solutions offer a comprehensive approach to meeting these challenges. For example, hybrid capacitor technology provides stable power delivery; ultra-low equivalent series resistance (ESR)

solutions afford efficiency in high-current power conversion, high-accuracy resistors enable precision power monitoring and wireless integration provides comprehensive power management. This article explores how these elements help create robust


power management systems for AI-driven data centres. It then introduces Panasonic solutions across all four areas and demonstrates their application in modern data centre environments.


Efficient data centre power delivery with hybrid capacitor technology Modern data centres require extensive power conversion. It is common for them to need hundreds of kilovolts AC (kVAC) from the grid. This voltage is first stepped down to tens of kVAC for distribution across the data centre campus. It is then further converted to hundreds of VAC for distribution to the equipment racks. At the rack level, AC power is converted to direct current,
