Analytical model of a resonator for PCB-embedded power conversion

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

High-Q Resonator with Integrated Capacitance for Resonance Power Conversion

Resonant power conversion at MHz frequencies is useful for miniaturization of power electronics, but requires resonators or inductors with high efficiency. Because litz wire is not effective above several MHz, an alternative winding structure for inductors is required for operation at these frequencies. In this paper, we present resonators with a multi-layer foil winding which can be constructe...

Mitigating Power Bus Noise with Embedded Capacitance in PCB Designs

This paper investigates the power bus noise and power bus impedance of printed circuit boards with four different kinds of embedded capacitance. These boards have power-ground plane pairs separated by a very thin layer of material with high dielectric permittivity. It is shown that embedded capacitance effectively reduces power bus noise over the entire frequency range evaluated (up to 5 GHz).
