In this paper the problem of improving the power quality for single phase power systems is approached. It is considered the particular case of voltage utility distortion due to the presence of a nonlinear load that generates some voltage harmonics in the network. The proposed solution includes a full-bridge serial voltage active filter equipped with a control law that guarantee, besides global internal...
Installation of a large number of small sources called distributed generation creates many problems in proper control of national (and European) power grid. At the same time new technologies especially power electronics and measurement data computing associated with smart grid allows to use better and conscious these distributed sources. This paper describes what problems the distributed generation...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
