The electrostatic transformer

Variable electrostatic transformer: controllable coupling of two charge qubits.

We propose and investigate a novel method for the controlled coupling of two Josephson charge qubits by means of a variable electrostatic transformer. The value of the coupling capacitance is given by the discretized curvature of the lowest energy band of a Josephson junction, which can be positive, negative, or zero. We calculate the charging diagram of the two-qubit system that reflects the t...

Electrostatic Field Analysis of 1200 Kv Testing Transformer by Boundary Element Method

Design of a 1200 kV power transformer is a real challenge for designer from dielectric point of view. It is possible to design a more compact transformer meeting even higher insulation levels with lesser insulation content. This has been possible with the introduction of sophisticated Computer-Aided Electrostatic Field Analysis. Analysis of the Lead Exit assembly of 1200 kV HV is presented. Two...

Transformer proteins

Proteins are generally believed to adopt a unique fold, defined by their amino acid sequence, under specific environmental conditions. These unique structures, in turn, endow proteins with one specific function. However, not all proteins obey the “1 amino acid sequence → 1 fold → 1 function” scheme. Moonlighting proteins that adopt one distinct threedimensional structure but can accomplish two ...

Relationship to the ideal transformer

A gyrator is a passive, linear, lossless, two-port electrical network element proposed in 1948 by Bernard D. H. Tellegen as a hypothetical fifth linear element after the resistor, capacitor, inductor and ideal transformer. Unlike the four conventional elements, the gyrator is non-reciprocal. Gyrators permit network realizations of two-(or-more)-port devices which cannot be realized with just th...
