INDUSTRIAL BATTERY CHARGER BY THYRISTOR FIRING ANGLE CONTROL

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...

DYNAMIC VOLTAGE RESTORER

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...

FOUR QUADRANT DC MOTOR CONTROLS WITHOUT MICROCONTROLLER

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...
