A Magnetic Integration Half-Turn Planar Transformer and its Analysis for LLC Resonant DC-DC Converters

IEEE Access, 2019
A high frequency planar transformer with integrated leakage inductance and half-turn secondary windings is proposed for LLC isolated DC-DC converters. The primary windings are wound on both the center leg and the sides leg of an EI planar ferrite core to

Personalized neurorehabilitative precision medicine: from data to therapies (MWKNeuroReha) – a multi-centre prospective observational clinical trial to predict long-term outcome of patients with acute motor stroke

BMC Neurology, 2022
Background Stroke is one of the most frequent diseases, and half of the stroke survivors are left with permanent impairment. Prediction of individual outcome is still difficult. Many but not all patients with stroke improve by approximately 1.7 times the

An integrated planar magnetic micropump

Microelectronic Engineering, 2014
This paper presents an integrated magnetic micropump that uses in-plane compliance-based check valves and a magnetically actuated membrane. The device, which allows for simple fabrication and system integration with other functional elements, consists of two functional layers both fabricated from poly(dimethylsiloxane) (PDMS).

Path integral quantization of the magnetic top

Physics Letters A, 1991
Abstract The magnetic top which is a realistic canonical model for quantum spin is quantized here by path integral methods. We determine the propagator and the wave functions in the space of Euler angles.
