Evaluation of DC-link voltage ripple in five-phase PWM voltage source inverters

open access: yesThe Journal of Engineering, 2019
This paper presents the analysis of the DC-link voltage switching ripple in five-phase PWM voltage source inverters with balanced load. The analysis is particularly important for the design and selection of a DC-link capacitor making it possible to meet ...

A method to measure EMI due to electric field coupling on PCB [PDF]

open access: yes, 1997
A new method to measure electric field coupling between PCB copper traces is presented. This method enables measurement of noise from waveforms obtainable from breadboard prototypes, which is available in an early stage in the design process.

Diagnostic Use of Testing for Novel Murine Autoantibodies for Sjögren Disease in the Rheumatology Outpatient Setting

open access: yesArthritis Care &Research, EarlyView.
Objective The goal was to assess the diagnostic performance of three novel autoantibodies (NA) for Sjögren disease (SjD) by comparing NA prevalence in patients with SjD, other autoimmune rheumatic diseases (ARDs), nonspecific chronic sialadenitis (CS), and controls.

Comprehensive comparison and analysis of non-inverting buck boost and conventional buck boost converters

open access: yesThe Journal of Engineering, 2019
The non-inverting buck boost (NIBB) converter has attracted significant attention in recent years, as it shares ground between input and output, and the voltage stress of switches is lower.

Study of Routing and Wavelength Assignment problem and Performance Analysis of Genetic Algorithm for All-Optical Networks [PDF]

open access: yes, 2010
All-optical networks uses the concept of wavelength division multiplexing (WDM). The problem of routing and wavelength assignment (RWA) is critically important for increasing the efficiency of wavelength routed All-optical networks.

High-CMRR stray-insensitive switched-capacitor differential input stage for A/D convertors

open access: yesElectronics Letters, 1986
A new stray-insensitive switched-capacitor differential input circuit for A/D convertors is presented. This circuit, which uses only switches and capacitors, completely rejects common-mode signals regardless of the values of the design capacitors and the stray capacitances.

Real‐World Longitudinal Data on the Impact of Hydroxychloroquine Blood Level Monitoring on Lupus Outcomes: Results of a Prospective Longitudinal Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), but the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to identify clinical factors that predict ...

PLL controller for achieving zero-voltage switching (ZVS) in inductorless half-bridge drive piezoelectric transformer resonant power supplies

open access: yesThe Journal of Engineering, 2019
Inductorless half-bridge, piezoelectric transformer (PT) resonant power supplies require careful control if zero-voltage switching (ZVS) of the MOSFETs is to be achieved.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...
