Wide bandgap devices enable design of power converters with high density. However, these require compact printed circuit board (PCB) layouts low power-loop stray inductance. Consequently, sensing device current in such minimal intrusion remains a challenge. This article presents PCB coil based sensor featuring inductance characterization. The is designed on double pulse test (DPT) for discrete ...

We demonstrate coherent tunable coupling between a superconducting phase qubit and a lumped-element resonator. The coupling strength is mediated by a flux-biased rf SQUID operated in the nonhysteretic regime. By tuning the applied flux bias to the rf SQUID we change the effective mutual inductance, and thus the coupling energy, between the phase qubit and resonator. We verify the modulation of ...

A meandered uniplanar compact electromagnetic bandgap structure is proposed. Meandered microstrip lines between adjacent cells are used to increase the equivalent inductance. As a result, the dimension of the proposed EBG structure is more compact and its frequency band-gap is wider than that of the conventional uniplanar EBG structure. Two patch arrays with and without an EBG structure were de...

In this paper, a new in-package high efficiency voltage down converter (VDC) is presented. Usually, quality factor of inductors is the main problem for generating high efficiency DC-DC Converters. In order to mitigate this problem, Bonding Wires with a new form are exploited in which four mutual inductions of bonding wire are used to increase the total inductance. This technique provides a high...

An inductance calculation method, which is based on calculating the current distribution of a fluxoid-trapped superconducting loop by using the expression of momentum and the Maxwell equations, is reconstructed to enable calculation of arbitrary 3D structures which have a ground plane (GP). Calculation of the mutual inductances of the superconductor system is also incorporated into the algorith...

The capacitive power transfer (CPT) system and inductively power transfer (IPT) system are the two typical wireless power transfer systems.

Firstly, the maximum power transfer capacity and its existing condition of the two wireless power transfer systems were analyz...

Introduction Rechargeable batteries are present in a variety of devices. The act of recharging them generally involves a charger wired to a wall outlet being plugged into the device. The charger can determine the type of charge the batteries receive and therefore determine the cycle life of the batteries. Wireless power transfer is on the cutting edge of the battery charging world. There are el...

We have investigated dc superconducting quantum interference devices ~SQUIDs! with loop areas 8 and 64 mm made by direct electron beam writing in YBa2Cu3O72x films with thickness 25 and 50 nm. The SQUIDs have maximum peak-to-peak voltage modulation of about 20 mV, which corresponds to the transfer factor dV/dF0;50–60 mV/F0 at 30–40 K. By measuring the mutual inductance of the SQUID signal line ...

− A Rogowski coil is well-known current-to-voltage transducer, and in order to use it for the high-accuracy measurement of AC current (at power supply frequency) all influencing quantities and their contribution should be recognized and analyzed. Therefore, in this paper the analysis of the partial influence due to the position of the primary conductor relatively to the secondary coil, with the...
