Design and kinematics of 4- DoF multi-purpose wearable mechanical arm (MUWA) support for enhanced operation stability
(IEEE, 2019)
A low-cost motor-less simple wearable mechanical arm support unit is presented as a viable alternative to todays assistive exoskeleton support units. By limiting the functionality of the device to stabilization rather than ...
An improved speed controller for PMSM drive with unbalanced load using load torque observer
(IEEE, 2019)
In order to overcome disturbance effects as load torque variations in Permanent Magnet Synchronous Motor (PMSM) of washing machines, an improved controller with feed forward compensation is presented in this paper. A few ...
A sub-sampling pulse-resonance OOK modulated digital ultrasound communication system for biomedical IoT
(Elsevier, 2019-11-01)
A pulse-resonance On-Off keying ultrasound communication microsystem is presented. It is a viable alternative to today's widely used RF technologies in order to avoid the associated health risks for a specific group of ...
A robust voltage control method for universal EV battery charger LLC resonant converters
(IEEE, 2019)
In this study, a novel control method for LLC resonant converter with wide output voltage range and constant switching frequency is proposed targeting wide range of Electric Vehicle (EV) battery charger standards. In ...
An experimental study of a bluetooth communication system for robot motion control
(IEEE, 2019)
This paper presents a method that aims to reduce the complex cabling problem in robotics applications, so as to prevent difficulties in troubleshooting processes and failures in case of cable breaks. Examples in the ...
16-elements helical antenna system integration with a solar cell powered IoT collector
(IEEE, 2019)
An 868MHz-915MHz 16-elements helical wire antenna array design with a solar-cell integration is presented. Each element is designed to be omni-directional with the corresponding tuning stubs and ground substrate. This is ...
Total harmonic distortion and power factor improvement technique for CRM flyback PFC converters
(IEEE, 2019)
In many of today's solid-state lighting applications, Critical Conduction Mode (CCM) Flyback PFC converter is a popular solution due to its limited component count and simple structure with respect to other SMPS topologies. ...
Class E resonant converter design for LED drivers
(IEEE, 2019-06)
The LED (Light Emitting Diode) lighting technology has been becoming widespread rapidly due to having advantages such as extremely long lifetime, compact structure and very low energy consumption. In the literature, various ...
