Frequency-domain-based complete loss model for 10 kV/1 MW solid-state transformer

The Journal of Engineering, 2019
This study proposes a frequency-domain-based loss model for dual active bridge (DAB) inside modular multi-level cascaded solid-state transformer (SST). Previously, the loss model is mainly derived in the time domain and requires enormous modelling effort.

Neonatal Deletion of Hand1 and Hand2 within Murine Cardiac Conduction System Reveals a Novel Role for HAND2 in Rhythm Homeostasis

Journal of Cardiovascular Development and Disease, 2022
The cardiac conduction system, a network of specialized cells, is required for the functioning of the heart. The basic helix loop helix factors Hand1 and Hand2 are required for cardiac morphogenesis and have been implicated in cardiac conduction system ...

Semiconductor loss calculation of DC–DC modular multilevel converter for HVDC interconnections

High Voltage, 2018
DC–DC modular multilevel converter (DC–DC MMC) is an attractive candidate for high-voltage DC (HVDC) interconnections since it can provide the required voltage matching, galvanic isolation and flexible power control abilities.

Evaluation of Frequency and Temperature Dependence of Power Losses Difference in Parallel IGBTs

IEEE Access, 2020
With the development of high power converters, safe operation of IGBT modules with parallel chips is of increasing importance. IGBT can work normally in safe range in the initial operation even if current imbalance is happening.

Interaction time and beam diameter effects on the conduction mode limit [PDF]

, 2012
Laser welding has two distinctive modes: keyhole and conduction mode. Keyhole mode is characterized by deep penetration and high welding speeds, while conduction mode has higher quality welds with no defects or spatter.

Sound Localization and Lateralization by Bilateral Bone Conduction Devices, Middle Ear Implants, and Cartilage Conduction Hearing Aids

Audiology Research, 2021
Sound localization in daily life is one of the important functions of binaural hearing. Bilateral bone conduction devices (BCDs), middle ear implants, and cartilage conduction hearing aids have been often applied for patients with conductive hearing loss

The Launching of Cold Clouds by Galaxy Outflows. V. The Role of Anisotropic Thermal Conduction

The Astrophysical Journal, 2023
Motivated by observations of multiphase galaxy outflows, we explore the impact of isotropic and anisotropic electron thermal conduction on the evolution of radiatively cooled, cold clouds embedded in hot, magnetized winds.
