Powering Systems Based on Complex ICs and the Quality of Utility AC Source: An End to End Approach for Protection Against Transients
8:30 am-9:30 am
By the turn of century, around 75% of the power generated was processed by power electronics. Ultra large scale integrated (ULSI) circuits which progress towards system on a chip (SoC) concepts are powered by DC power rails as low as 1.2 to 0.8 Volts. These two scenarios have made the demands within the power conversion interface complex. Whilst uninterruptible power supplies and advanced power conditioning with surge protection have become essential in providing clean and reliable AC power, compact ultra low DC voltage sources with energy backup, fast transient response and power management have become mandatory in powering modern electronics. This paper highlights the need for modeling and researching into the overall aspects within the power conversion interface created by the complex world of SoC, computer networks, and electronic systems demanding 99.999% or higher reli-ability. Practical and mathematical approaches to study the effects of transients carried through the overall power conversion interface and their effects will be discussed in the paper.
