A MATRIX Solution to Solid State Devices for Scalable, Integratable, and Efficient Signal and Power Processing
Abstract
Abstract Many years ago a missing fundamental electrical element, the gyrator, was proposed based on transduction of magnetic flux and electric charge by magnetoelectric (ME) interactions. It is a 4-wire element that has important key characteristics that the other four fundamental circuit elements (capacitor, resistor, inductor, and transformer) do not have, which includes: (i) the ability to convert current directly into voltage, and vice versa; and (ii) the ability to reflect the other network elements as their duals. It is the goal of this program to prove the principles of such gyrators, determining what might be their benefits and limitations. The tasks are as follows: (i) Fabricate discrete solid state gyrator elements of various geometrical designs and materials couples. Since we will prove principles, efforts will focus on the frequency range of fr=100 kHz. This size allows conventional turns coil to be used, and at the same time makes the electrode patterning and fabrication steps easier. (ii) Characterize I-V power conversion properties of solid state gyrators (Li). Studies will include maximum power conditions, ranges, and linearity. Furthermore, the DC bias tunable electrical characteristics will be investigated: including E-field tunable inductance (?L/?E) and resonance frequency (?f/?E), and H-field tunable capacitance (?C/?B). This will allow for the identification of the merits and performance limitations of the various gyrator structures. (iii) We will determine the potential of gyrator components for power electronic modules. Applications will include I-V transformers for MPC power converters (switch mode for solar) or receivers for wireless energy transmission. We will determine the opportunities offered with regards to enabling new device performances.
