R Dump Converter without DC Link Capacitor for an 8/6 SRM: Experimental Investigation

open access: yesThe Scientific World Journal, 2015
The objective of this paper is to investigate the performance of 8/6 switched reluctance motor (SRM) when excited with sinusoidal voltage. The conventional R dump converter provides DC excitation with the help of capacitor.

Comparative Studies of Different Control Strategies of a Dynamic Voltage Restorer Based on Matrix Converter [PDF]

open access: yes, 2012
A dynamic voltage restorer (DVR) with no energy storage is studied. By using a matrix converter instead of the conventional AC/DC/AC converters, elimination of the DC-link capacitor is possible.

Calculation and control of DC bias current distribution in an AC power system around a typical ±800 kV DC grounding electrode

open access: yesThe Journal of Engineering, 2019
When the ultra-high-voltage direct current (UHVDC) transmission system operates in a monopolar ground return mode, an enormous DC current flows into earth via the DC grounding electrode in the converter station and then comes into the AC system around ...

Fuzzy Controlled Parallel AC-DC Converter for PFC

open access: yesAdvances in Electrical and Electronic Engineering, 2011
Paralleling of converter modules is a well-known technique that is often used in medium-power applications to achieve the desired output power by using smaller size of high frequency transformers and inductors. In this paper, a parallel-connected single-phase PFC topology using flyback and forward converters is proposed to improve the output voltage ...

Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...

New Power Electronics Converter Interfacing a Hybrid Dc/Ac Microgrid [PDF]

open access: yes, 2013
poster abstractDistributed loads can either be ac or dc. It is also possible to combine ac and dc subgrids to form the hybrid microgrid. The main advantage of the hybrid microgrid is that it has higher efficiency and lesser power conversion. In this work
