Lightweight, high-frequency transformers [PDF]
, 1983 The 25-kVA space transformer was developed under contract by Thermal Technology Laboratory, Buffalo, N. Y. The NASA Lewis transformer technology program attempted to develop the baseline technology. For the 25-kVA transformer the input voltage was chosen

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

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.

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 ...

Study of the decoupling magnetic integrated high‐frequency transformer for DC/DC converter
IET Power ElectronicsThe isolated DC/DC converter plays an irreplaceable role in the development of the DC microgrid. However, the multiple discrete high‐frequency transformers occupy considerable volume in power converters due to the connection of multiple isolated ...

Variation of Core Loss in High-Frequency Transformers Under Different Load Conditions
IEEE Open Journal of the Industrial Electronics Society, 2023 Typically, the core loss of transformers is considered constant, regardless of the load conditions on the secondary side. However, this assumption is no longer valid for high-frequency transformers (HFTs).
