Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object

open access: yesAdvanced Engineering Materials, EarlyView.
We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

IGBT Fault Current Limiting Circuit

IEEE Industry Applications Magazine, 1995
Circuits are proposed which, by limiting the fault current magnitude, extends the short-circuit withstand time of high-efficiency (high-gain) IGBTs (insulated-gate bipolar transistors). Limiting of the fault current magnitude also results in reduced turn-off voltage transients, a desirable byproduct, especially for higher current modules. Moreover, the

Multicell Fault Current Limiter

IEEE Transactions on Industrial Electronics, 2014
A multicell fault current limiter (MCFCL) is proposed in this paper. The MCFCL is composed of multiple fault current limiting cells. Each fault current limiting cell consists of a fault current limiting inductor and a power electronic module. The proposed MCFCL has the flexibility in expanding the operation voltage by increasing the number of fault ...

Superconducting fault current limiters

IEE Colloquium on High Tc Superconducting Materials as `Magnets', 1995
Fault current limiters (FCLs), superconducting or otherwise, have the potential to reduce fault levels on electricity power networks, and may ultimately lead to lower rated components (i.e. cheaper) being used, or to increased capacity on existing systems.
