TPEL – Fundamental Performance Limits of High-Frequency Passive Components

Our new paper accepted for publication in IEEE Transactions on Power Electronics (pdf) explores the potential for new types of passive components and shows that there are exciting opportunities.

  • Analysis of volumetric energy densities of various storage mechanisms shows that mechanical storage may offer order-of-magnitude improvement over conventional electromagnetic passive components.
  • Considering only the limitations imposed by material properties and not by available fabrication methods, both piezoelectric and LC resonators have fundamental performance limits that are much higher than the capabilities of commercial passive components in use today.
  • A prototype 1 cmintegrated LC resonator optimized for low loss is capable of handling 7.42 kW with only 0.06% loss attributable to the resonator when used in a resonant switched-capacitor circuit.
