Mitigation of Common Mode Voltage Issues in Electric Vehicle Drive Systems by Means of an Alternative AC-Decoupling Power Converter Topology
(MDPI, 2019-08-30)
Electric vehicles (EV) are gaining popularity due to current environmental concerns. The electric drive, which is constituted by a power converter and an electric machine, is one of the main elements of the EV. Such machines ...
Design and implementation of a droop control in d-q frame for islanded microgrids
(The Institution of Engineering and Technology, 2013-09-01)
The droop control method is usually selected when several distributed generators (DGs) are connected in parallel forming an islanded microgrid. This is because of the advantages it offers such as flexibility, absence of ...
Analysis of DC–DC power supply systems for pulsed loads from green electronics perspective
(The Institution of Engineering and Technology, 2015-06-01)
Discontinuous loads frequently compromise the performance of their power source and electronics. They cause the voltage and current ripple at the source and load, and introduce electromagnetic interferences. Also, they ...
General aspects, hierarchical controls and droop methods in microgrids: A review
(Elsevier, 2012-10-17)
Distributed generation is emerging as a new technology for supplying the increasing demand for electricity. Microgrids are attracting a great deal of attention since they integrate distributed generation in the main grid ...
Joint cost of energy under an optimal economic policy of hybrid power systems subject to uncertainty
(Elsevier, 2015-08-01)
Economical optimization of hybrid systems is usually performed by means of LCoE (levelized cost of energy) calculation. Previous works deal with the LCoE calculation of the whole hybrid system disregarding an important ...
Next generation electric drives for HEV/EV propulsion systems: Technology, trends and challenges
(Elsevier, 2019-08-23)
In recent decades, several factors such as environmental protection, fossil fuel scarcity, climate change and pollution have driven the research and development of a more clean and sustainable transport. In this context, ...
Loss and stress reduction in VSI devices for EVs using general discontinuous PWM
(2016-07-06)
In this paper, a new carrier based discontinuous pulse width modulation (DPWM) strategy for voltage source inverter (VSI) is presented in order to use in electric vehicles (EV). The basic idea of DPWM techniques, is clampimg ...
Analysis of impedance and current distributions in parallel IGBT design
(IEEE, 2017-08-07)
Power electronic applications need high voltage and current ranges which are impossible to obtain with discrete devices. Parallelization technique is a solution to increase power converter current capacity. Current ...
