A comparative study on fault detection and correction techniques on active magnetic bearing systems
(IEEE-Institute of Electrical and Electronics Engineers, 2007)
In this paper, the authors distinguish between three real-time fault detection, correction and identification schemes for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Historical fault ...
On the role of magnetic shunts for increasing performance of transverse flux machines
(IEEE, 2017)
This paper presents work completed in order to investigate the importance of magnetic shunts in transverse flux machines. Two types of transverse flux machines with different configurations were designed and tested in the ...
Fuel allocation and lockout system
(IEEE, 2018)
In transport and Logistics business with the fierce competition, avoiding fuel theft through monitoring and management is a major concern in Africa. With the steadily increase in fuel price, fuel theft and fraud poses a ...
Data logger and companion application for time-of-use electricity
(IEEE, 2018)
Electricity generation is becoming more expensive, hence Time-of-Use (ToU) electricity tariff structures, such as Eskom Megaflex are implemented. The companion application is an integrated solution designed for use with ...
Impact of thermoelectric cooling modules on the efficiency of a single-phase asynchronous machine
(Energy Research Centre, University of Cape Town, 2014)
In this paper, the authors present the impact of thermoelectric
cooling modules (TECMs) on the efficiency
of a single-phase asynchronous machine.
TECMs are used to lower the stator winding temperature
and core temperature ...
Energy management by means of SMD model analysis for AMB systems with eccentricity
(IRET (Institute of Research in Engineering and Technology), 2013)
This paper provides the spring-mass-damper (SMD)
model analysis of a radial active magnetic bearing (AMB)
system that displays eccentricity. Energy management of AMB
systems can be done by means of a detailed SMD model ...
Energy management by means of PLC for a solar powered ultra-capacitor streetlight system
(IRET (Institute of Research in Engineering and Technology), 2013)
This paper presents the design of an energy
management programmable logic controller (PLC) control
program for a solar powered ultra-capacitor and battery
powered streetlight system. A PLC is used to control the flow ...
Electrical circuit modelling of double layer capacitors for power electronics and energy storage applications: a review
(MDPI, 2018)
There has been increasing interests in the use of double layer capacitors (DLCs)—most
commonly referred to as supercapacitors (SCs), ultra-capacitors (UCs), or hybrid capacitors (HCs)—in
the field of power electronics. ...
Renewable energy thermoelectric module air conditioning system-design factors: a review
(Research India Publications, 2018)
The conventional air conditioner is fast becoming a noticeable
energy user that negatively affects the supplier’s ability to
supply energy during peak periods when the country’s energy
need rises. The Clean Development ...
PWM and duty ratio switching of multiple input converters using FPGAs: a digital logic circuit and VHDL hybrid approach
(Science Publishing Corporation, 2018)
This paper presents work that addresses the need for the simultaneous switching of the gate signals of controllable switches in multiple
input DC-DC converters. A hybrid approach of implementing the gate signal switching ...
