Abstract

DC to DC converters are important in portable electronic devices. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement than that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage, and possibly even negative voltage). Switched DC - DC converters offer a method to convert one level of voltage to other, thereby saving space instead of using multiple batteries to accomplish the same thing. This work aims at designing a DC-DC Buck converter with input 28V and regulated 5V DC as output.

Abstract

Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Of all the renewable sources of energy, one of the most easily trappable is the solar energy. This project aims at designing a solar panel that taps the maximum output power through a maximum power tracking technique. The solar panel has been designed by taking the diode equivalent circuit of a PV cell and connecting these individual cells in a combination to generate the required power output. Through 3 point Maximum Power Tracking Technique, the maximum output is fed to boost converter that steps up the voltage to the value as determined by the design of the boost. This design is simulated in Mat lab Simulink.

Abstract

This paper describes about the functioning of Automatic Waste Segregator plant and the role played by the electrical drives in such plants. A prototype of this plant has been developed with a view of having the ability to expand such that not just waste from a single house gets segregated but the wastes of a locality or perhaps a city also. For such large scale industrialization of plants such as these, control of motors and drives is most important. The working of the prototype of this plant is brought about by the use of sensors such as ultrasonic sensors, moisture sensor, infrared sensor and metal sensors. It is capable of separating wastes into wet waste, dry wastes and metallic wastes. The prototype also has a conveyer belt and a motor on which a platform which has bins attached to it are mounted. The prototype uses DC motors, for a plant which should be capable of handling large quantities of waste advanced drives and motors are required. The requirements and possible drives and motors for such large scale operation are also discussed in this paper.
