DC Bus Switching Performance as Determined by Commutation Loop Parasitics and Switching Dynamics


In this article a 250 kW all-SiC inverter evaluation kit designed around low-inductance, high-speed power modules is used to demonstrate the DC bus switching performance resulting from the interaction among commutation loop parasitics and the switching dynamics. The interplay among the DC bus structure parasitics and near-RF switching dynamics can be quantified in both the time and frequency do... » read more

Correlating Software Execution With Switching Activity To Save Power In SoC Designs


There is probably no more pointless waste of energy than lighting and heating a room that is empty. The obvious optimization: notice that no one is there and turn off the lights. It works the same on an SoC or embedded system. To save energy, system developers are adding the ability turn off the parts of the system that are not being used. Big energy savings but with no compromise to functional... » read more
