Episode notes
Data Center Power Per Rack Has Exploded
- Data centers' power needs have jumped from ~2 kW PSUs years ago to 5–12 kW systems today, driving major demand for higher-efficiency conversion.
- Steve Tateosian highlights that minimizing energy use via more efficient conversion is now a central industry focus due to scale and location concerns.
Wide Band Gap Parts Enable Higher Frequency Conversion
- Wide band gap devices (GaN and SiC) are enabling much higher switching frequencies and boosting overall power-supply efficiency.
- Steve explains this hardware shift also forces changes in microcontrollers and control strategies to handle faster switching reliably.
Design Power Systems As Integrated Hardware And Software
- Approach power systems as an integrated hardware plus software problem rather than isolated components.
- Infineon pairs industry-leading power devices with MCUs and PowerSuite libraries to speed development and improve reliability.
