Efficiency and Power Density Optimization of Three-Level TP PFC
(IEEE, 2021)
Si based three-level (3L) totem-pole (TP) Power Factor Correction (PFC) topology is a low cost alternative
to two-level TP PFC with wide-band gap devices providing high power density and high efficiency. This
study ...
Simplified Method to Analyze Drive Strengths for GaN Power Devices
(IEEE, 2021)
GaN power switches enable ultra-fast switching speeds, yet, the maximum gate drive strength is mainly
limited by the voltage overshoot across drain-source junction. There is a complex relationship between
the power loop ...
Analytical Modelling and Optimization of Gapped Core Magnetics in LLC Converter
(IEEE, 2021)
LLC converter design remains a challenging task as it is not straight-forward to choose the switching
frequency range that can provide ZVS covering application dependent voltage gains, considering the fact
that it is a ...
System-Level Design Approach for LLC Converters
(IEEE, 2021)
LLC resonant converters are designed with a specified resonant frequency that is usually determined
based on the experience of the designers while impacting the losses and the dimension of the converter. In
this paper, ...
Search Space Sampling by Simulated Annealing for Identifying Robust Solutions in Course Timetabling
(Institute of Electrical and Electronics Engineers Inc., 2020)
For many combinatorial optimization problems, it
is important to identify solutions that can be repaired without
degrading solution quality in case changes in the data associated
with the constraints make the initial ...
Memory-Assisted Dynamic Multi-Objective Evolutionary Algorithm for Feature Drift Problem
(IEEE, 2020)
In this paper, we propose an enhanced feature
selection algorithm able to cope with feature drift problem
that may occur in data streams, where the set of relevant
features change over time. We utilize a dynamic ...
LabVIEW FPGA Based BLDC Motor Control by Using Field Oriented Control Algorithm
(IEEE, 2020)
BLDC (Brushless Direct Current) motors are widely
used today due to its high reliability and high efficiency. These
motors are synchronous motors that have a linear relationship
between voltage-speed and current-torque. ...
Structural Performance of Reciprocal Structures Formed by Using Islamic Geometrical Patterns
(Ecaade-Education & Research Computer Aided Architectural Design Europe, 2021)
Many Islamic geometric patterns consist of stripes which are recognizable in the
two dimensional patterns. These stripes systematically pass over or under each
other, thus they create a tessellation. This system has the ...
Detail Investigation on Success of the Filters and Classification Algorithms for Determining Pneumonia Disease
(Institute of Electrical and Electronics Engineers Inc., 2021)
Today, as a result of the widespread use of electronic
stethoscopes, lung sounds can be recorded and transferred to
a computer. Thus, it was possible to analyze the lung sounds.
Healthy lung sounds are called normal ...
Classification of Covid-19 X-ray Images Using Tridiagonal Matrix Enhanced Multivariance Products Representation (TMEMPR)
(Institute of Electrical and Electronics Engineers Inc., 2021)
Medical images are crucial data sources for diseases
that can not be diagnosed easily. X-rays, one of the medical
images, have high resolution. Processing high-resolution images
leads to a few problems such as difficulties ...
