Cooperative regulation of imbalances in three-phase four-wire microgrids using single-phase droop control and secondary control algorithms
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Collaborative control of power converters operating in microgrids with unbalanced single-phase loads is difficult to achieve, considering that the voltages and currents have positive-, negative-, and zero-sequence components. ...
A new space-vector-modulation algorithm for a three-level four-leg npc inverter
(2017)
For power conversion systems interfaced to four-wire supplies, four-leg converters have become a standard solution. A four-leg converter allows good compensation of zero-sequence harmonics and full utilisation of the dc-link ...
Técnicas vetoriais de modulação por largura de pulso para conversores trifásicos de quatro-braços
(Universidade Federal de Minas GeraisUFMG, 2005-09-30)
This work study the strategies for three-phase four-leg voltage source converter. Carrier-based pulse width modulator (PWM) method and space vector PWM method are discusses for the three-phase and four-leg voltage source ...
A repetitive control system for four-leg matrix converters feeding non-linear loads
(2013)
Generators working with variable speed, rather than fixed speed, have many advantages, which are well documented in the literature. Higher efficiency, better power to size ratio and less mechanical stress in the system are ...
