The simulation of a new high frequency transformer
Journal of Energy Systems, 2022 Core losses of transformers motivate many engineers and scientists to design and implement different transformers for their specific aims. Since there exists a growing interest on high frequency applications in today’s world, design and optimization studies of a magnetic fluid core transformer (MFCT), having an easy and cheap production approach in ...

Low and high frequency model of three phase transformer by frequency response analysis measurement
Open Physics, 2018 The behavior analysis of the transformer is usually achieved by the frequency response analysis (FRA), which is obtained by the application of a very low AC voltage in over a wide frequency range.

Pediatric Blood &Cancer, EarlyView.ABSTRACT We sought to identify potential early risk biomarkers for lung disease in children post‐allogeneic HCT. Patients with pulmonary function tests 3 months post‐transplant and plasma samples between days 7 and 14 post‐HCT were included. Six of 27 subjects enrolled had reduced forced expiratory volume 1 (FEV1) z scores.

Investigating inter-turn fault in transformer using TTR and FRA [PDF]
, 2019 Transformers are one of the significant elements in the power system network. The Transformer function is to step up and down the voltages. When the transformer operating in high load, it exposes to failures.

Analogue CMOS high-frequency continuouswavelet transform circuit
Electronics Letters, 1999 A 16-channel analog CMOS high-frequency continuous wavelet transform circuit has been realized. The circuit performs a time-frequency decomposition of a high-frequency input signal. A 100 MHz operating frequency, 45 MHz bandwidth, and 40 mW/channel power dissipation have been achieved using a 0.5 /spl mu/m CMOS process.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Surveillance imaging aims to detect tumour relapse before symptoms develop, but it's unclear whether earlier detection of relapse leads to better outcomes in children and young people (CYP) with medulloblastoma and ependymoma. This systematic review aims to identify relevant literature to determine the efficacy of surveillance magnetic ...

Less-conventional low-consumption galvanic separated MOSFET-IGBT gate drive supply [PDF]
, 2017 A simple half-bridge, galvanic separated power supply which can be short circuit proof is proposed for gate driver local supplies. The supply is made while hacking a common mode type filter as a transformer, as the transformer shows a good insulation, it
