This paper begins by illustrating the issue of switch stresses on synchronous rectifiers (SRs) which happens during the hot plug-in and plug-out operation turn on and off moment of the synchronous rectification in isolated non-regulated Dc-Dc converters, such as the single stage unregulated bus converter. Next, full analysis of the working principle of this unfavorable phenomenon is presented theoretically...
This paper proposes an improved current control scheme for the rotor-side converter of a doubly-fed induction generator (DFIG) wind power generation system. The control scheme consists of a proportional (P) controller and a harmonic resonant (R) regulator tuned at the grid frequency. Thus, the positive and negative sequence components of rotor current are fully regulated by the PR controller without...
