Voltage regulation is a main key factor for stable power system. Recent years the electronics equipment growth is rapidly increase. These electronics devices are voltage sensitive devices.
To maintain the grid system voltage equal or near to nominal level, the DVR plays major roll.
The 31 level inverter is proposed in this study to reduce number ...

An high non-linear diode bridge rectifier has been used in the electric vehicle charger for the use of DC voltage at only the DC-DC converter input but also to implement significant power quality problems only at existing AC input.
By eliminating their input bridges, such problems developed a tremendous a need boost the Performance of power quali...

This paper presents a PFC (Power Factor Correction) based BL-Luo (Bridgeless-Luo) converter fed BLDC (Brush less DC) motor drive. A single voltage sensor is used for the speed control of BLDC motor and PFC at AC mains. The voltage follower control is used for a BL-Luo converter operating in DICM (Discontinuous Inductor Current Mode). The speed of t...

Power quality is an important concern for practical microgrid (MG) applications due to the widespread use of non-linear loads, and it is characterised by the implicit trade-off between voltage quality in the MG nodes and harmonic current sharing between distributed generators (DGs). Active and passive filters can be used to address this problem...

Power system consist of large number of nonlinear load which causes power quality issues. Sensitive components like electronic devices, medical equipment working on power supply are vulnerable to power quality problems. Voltage sag ,Swell ,harmonics ,noise are considered to be some important power quality issues .Voltage dips are the major disturb...
