A single phase boost converter in both discontinuous inductor current mode (DICM) and continuous inductor current mode has been dealt in order to reduce total harmonic distortion (THD) of source side current and improve power quality of source. Results obtained by proposed technique have been compared with the conventional rectifier operation. The proposed schemes have been simulated on MATLAB/SIMULINK...
The recent growth in the use of power electronic converters which are considered as nonlinear loads have problems of drawing non sinusoidal current and reactive power from source which in turn pollutes the power quality. This paper presents the power quality problems and methods for its correction. Two control strategies (p − q instantaneous power theory and d − q synchronous reference frame theory)...
When a transformer is energized, magnetizing inrush current occurs due to temporary overfluxing in the transformer core. The magnitude of inrush current may be as high as ten times of transformer rated current which causes maloperation of differential protection system. This inrush current contains decaying DC and dominant second harmonic components which may cause undesirable effects like poor power...
