ABSTRACT: The project is designed for charging batteries by DC from AC power supply. DC power for a battery charger is derived from a thyristor controlled rectifier system. AC power is applied to a bridge rectifier comprising of diodes and a triac getting desired...
ABSTRACT As communities and industries continue to expand, delivering power becomes more challenging– electricity grids reach capacity during peak periods, while providing electricity off the grid becomes more expensive. In India the use of electronic loads is...
ABSTRACT: Dynamic voltage restorer (DVR) is a custom power device used in electrical distribution system for power quality improvement. It ensures regulated voltage supply to the sensitive loads, even in case of voltage sag and swell disturbances in the distribution...
ABSTRACT: In this paper, a PIR based security system which saves the power consumption and the memory space of the recording system has been proposed. Passive Infrared Radiation (PIR) sensor detects the change in infrared radiation of warm blooded moving object in its...
ABSTRACT: The project is designed to develop a four quadrant control system for a DC motor. The motor is operated in four quadrants i.e. clockwise; counter clock-wise, forward brake and reverse brake. The four quadrant operation of the dc motor is best suited for...
Abstract: The common problem with three-phase supply is absence of any one of the phase .this leads to damage of induction motor or any three – phase load .this project is designed to monitor the presence of three phase and to display condition of each phase on...
