Measurements and Analysis of Electric Power Quality
Abstract: The ideal supply voltage is pure sinusoidal voltage with nominal frequency and nominal amplitude.Any variation from this is considered as a power quality event or a disturbance. One importantaspect in the field of power quality is monitoring and control of the qualitative parameters of theelectrical energy according to today’s standards. In that way, a big attention is paid to define thedisturbances and determination of procedures for their measurement. A large …

A high Regulated Low Ripple DC Power Supply based on LC Filter and IGBT
Abstract: Filaments operating at a high temperature region would require ripple free current constant power source for their heating purposes. Introduction of ripple in the power supply would result in high power loss, aberrant, unpredictable temperature rise etc. High current ripple can also extenuate the life of electrolytic capacitors used in the circuit. In this paper we propose a scheme in which we would not only use simple, low cost, easily …

A Novel PWM Based STATCOM Controller for Power Quality Enhancement in Distributed System
Abstract: Static Synchronous Compensator has the capability for the improvement in damping factor and stability by managing the reactive power output. As the STATCOM will itself absorb the reactive power which comes from the distribution line when we apply the capacitive load. To get the higher performance of STATCOM we are mainly depend over control algorithms. As the real power factor has been absorb by the STATCOM at the time when …

Revolutionizing EV Battery Charging: Enhancing Power Factor with Modified Bridgeless Landsman Converter
Abstract: The work focuses on the design and implementation of an innovative battery charger for electric vehicles (EVs) with a significant improvement in the power factor at the front end. The existing EV chargers often suffer from poor power factor, leading to increased losses and reduced efficiency. An altered Landsman power factor correction (PFC) converter is used in place of the traditional diode bridge rectifier (DBR) in order to solve this …

A Simplified Indirect Control Scheme for Shunt-active Power Filters
Abstract: This paper presents a simplified indirect control scheme for shunt-active power filters for compensating harmonic currents and improving power factor. The control is based on the simple method for generation of the reference compensating current. The reference compensating current is obtained by subtracting load current from reference source current. PI controller is used to adjust the amplitude of the reference source current that regulates the DC capacitor voltage. Hysteresis band …

Design and Implementation of A 4-bit Multiplier using Wallace Tree Architecture in 180 nm Technology
Abstract: Over the period of last decade, power dissipation has become one of the most important factors for VLSI designers in the design of most digital systems. Even though the speed and area are considered to be the critical factors in design of digital systems, there is a trade of with power consumption. Adders and multipliers are the most important arithmetic units in a processor and the major sources of power …
