POWER STORAGE DETAILS Block diagram: The voltage generated by the source (generator) is not of pure dc. This has to be rectified before storage. A diode rectifier then provides a full-wave rectified voltage that is initially filtered by a simple capacitor filter to produce a dc voltage. Block diagram (Power supply) Working principle: The Full Wave Bridge Rectifier Full Wave Bridge Rectifier uses four individual rectifying diodes connected in a closed-loop "bridge" configuration to produce the desired output. The main advantage of this a bridge circuit is that it does not require a special center-tapped transformer, thereby reducing its size and cost. The single secondary winding is connected to one side of the diode bridge network and the load to the other side as shown below. The Diode Bridge Rectifier The four diodes labeled D1 to D4 are arranged in “series pairs” with only two diodes conducting current during each
Pump:- A small, electrically powered pump A large, electrically driven pump (electro pump) for waterworks near the Hengsteyee, Germany. A pump is a drive used to move fluids, such as liquids or slurries, or gases. A pump displaces a volume by physical or mechanical action. One common misconception about pumps is the thought that they create pressure. Pumps alone do not create pressure; they only displace fluid, causing a flow. Adding resistance to flow causes pressure. Pumps fall into five major groups: direct lift, displacement, velocity, buoyancy and gravity pumps. Their names describe the method for moving a fluid . Types: Positive displacement pumps A lobe pump Mechanism of a scroll pump A positive displacement pump causes a fluid to move by trapping a fixed amount of it then forcing (displacing) that trapped volume into the discharge pipe. A positive displacement pump can be further classified accordin
