Novel ZVS S-TCM Modulation of Three-Phase AC/DC Converters

open access: yesIEEE Open Journal of Power Electronics, 2020
For three-phase AC-DC power conversion, the widely-used continuous current mode (CCM) modulation scheme results in relatively high semiconductor losses from hard-switching each device during half of the mains cycle.

Modulated Model-Free Predictive Control With Minimum Switching Losses for PMSM Drive System

open access: yesIEEE Access, 2020
A modulated model-free predictive control with minimum switching losses (MSL-MMFPC) is proposed to improve the steady-state performance and reduce the switching losses for a permanent magnet synchronous motor (PMSM) drive system.

Switching losses in three-phase voltage source inverters [PDF]

open access: yes, 2016
The efficiency of three-phase voltage source inverters depends mainly on power losses that occur in semi-conductor elements. Total losses in these elements are a sum of conduction losses and switching losses.

Reduction of switching losses and passive components rating in series-connected current source inverters [PDF]

open access: yes, 2023
The current source inverter (CSI) is widely used in medium voltage drives due to its simple configuration, reliable short-circuit protection, and low dv/dt issue.

Effects of Hearing Loss on Maintaining and Switching Attention

open access: yesActa Acustica united with Acustica, 2018
The ability to intentionally control attention based on task goals and stimulus properties is critical to communication in many environments. However, when a person has a damaged auditory system, such as with hearing loss, perceptual organization may also be impaired, making it more difficult to direct attention to different auditory objects in the ...

Optimisation of the Synchronous Rectifier in Phase Shift Full Bridge Converters for High-Frequency Applications

open access: yesPower Electronics and Drives
Efforts to minimise the size and material usage of power converters are reflected in efforts to increase the switching frequency. The problem is that semiconductor switching losses are proportional to the switching frequency, so it is necessary to find ...
