Active power filters have demonstrated effective harmonic compensation of dynamic nonlinear loads in DC traction systems. In this paper, it is proposed a practical methodology for allocation of active power filters in DC traction systems using the least number of filters and minimizing the size of th...
This paper proposes a novel sliding mode control (SMC) scheme with a repetitive sliding surface for shunt active power filters (SAPF) to enhance the system robustness and eliminate harmonic current tracking errors. Traditional control sc... Y Gao,X Li,W Zhang,... - 《Energies》 被引量: 0...
