Some people have helped in the basic formularization and there were sources that helped me in giving the ideas a physical form/shape. I am extremely grateful to my mentor, Mr. Shekhar Jha for his invaluable guidance in the project right from the beginning. His vital support helped the project to take a logical and suitable shape. I take this opportunity to thank the School authorities, for extending their full support and cooperation in the project. Last but not the least; I would like to thank everyone who has offered a helping hand when required CERTIFICATE This is to certify that Somrat Dutta (Roll_No:…..……) student of Class XII, Delhi Public School, Siliguri has completed the project titled. “Full Wave Rectifier” during the academic year 2016-17 towards partial fulfillment of credit for the Physics Project evaluation of AISSCE 2017, and submitted working model and satisfactory repo...

Power conversion is an essential part of modern life, and probably the most important for practical purposes in electronics is AC to DC conversion. Rectifiers are the essential circuits used to transform AC to DC and they may fall into one of the following categories: • Half-wave rectifier • Center-tapped full-wave rectifier • Bridge rectifier The functionality of these rectifiers is the same, i.e. In this guide, we’ll look at the design and simulation of a full-wave H-bridge rectifier for single-phase and three-phase power conversion. Both may be used in an industrial setting, including in small control modules that my company has developed for client projects. They are ubiquitous in other electronic devices, and building a simulation with these is important for seeing how they can deliver power to downstream circuits with high efficiency. A Uncontrolled single-phase bridge rectifier Sometimes, you’ll see the above rectifier drawn out in an H-bridge configuration, which is shown below. This configuration is exactly the same as the above configuration. Also shown below is a three-phase rectifier for comparison, which simply uses 6 diodes instead of 4, with 2 series diodes used to control current flow for each phase in a three-phase AC connection. The differences between the two types of rectifiers should be evident from their waveforms; the three-phase rectifier provides much lower ripple, but at 1.5x the frequency of the single-phase rectifier. Single-phase vs. three-phas...

This paper presents the design and construction of a dual regulated ±0-35Volts DC power supply that will serve a dual purpose of providing a positive and negative DC output of different values for use in miniaturize electronic appliances such as laptops, TV, and Telephone. It may also be useful in various domestic and laboratory experimental purposes. LM317 and LM337 were used as positive and negative voltage regulators respectively. The circuit was built with preferred values of components with an AC input of 220Vrms, 50Hz that was step down using a designed center tapped transformer (37V 0 37V). The total output power was found to be 272.34W. The total power loss was determined to be 35.66W with an efficiency of 88.42%. The DC voltage transfer functions at the positive and negative terminals were found to be 0.966 and 0.969 respectively. The differences between the voltages of the developed circuit and the designed values were found to be 3.45% at the positive terminal and 3.18% at the negative terminal which was achieved using the percentage error method. This device is useful in an application that uses bi-directional amplifiers and dual power supply such as operational amplifiers mostly found in TV/Radio systems. Electrophoresis machine is a machine used in detecting the genotype of human being which basically is AA, AS, SS. This work has successfully demonstrated how different electronic components such as diode, resistors, capacitor can be used to actualize a fascin...

Introduction This intractable page will guide you through all the steps necessary to build a full wave bridge rectifier. It is useful in converting AC current to DC current. Parts (with purchasing links) (Pictures of the parts are included with corresponding order) Four Diodes: One 1kΩ Resistor: One 470μF Capacitor: One Breadboard: One Wire Kit : One Transformer: The type of transformer provided above has a turns ratio of 115:6.3, which is slightly off from the 115:6 transformer I used. However, this extent of difference in the output voltage will not cause a major change in the results and will not blow the diodes nor the resistor. Also, pretty much all major types of diodes should be compatible with this project, but make sure you check that the peak repetitive reverse voltage is higher than the output of the transformer. *For People Who Live in Countries that Use 220V AC The output voltage from the transformer will double, but that would not blow the components if you get the correct types. Otherwise, you could double the resistance on the resistor or use a transformer that has a turns ratio close to 220:6. You could use the schematic provided in the pictures (P1) as a guide to build the circuit. Or you could build the circuit using the pictures of the circuit I built on a breadboard (P2 and P3). Make sure that the capacitor is oriented in a way that its long leg (positive leg)is plugged into the top hole (hole G4 on my breadboard). The orientation of the resistor does ...

Project Overview In this project, we will improve upon the previous Figure 1. Schematic diagram of a full-wave bridge rectifier circuit with capacitive filtering. The capacitor will act as a simple Figure 2. The effect of capacitor filtering on the full-wave bridge rectifier output. This experiment involves constructing a If desired, you canmake this device its own self-contained 120 VAC/DC power supply. To do this, you would need to add all the componentry of the low-voltage AC supply to the AC inputside of this circuit: a Parts and Materials • Low-voltage AC power supply • Bridge rectifier pack (with a recommended rating of 25 A and 50 V) • • Four bananajack-style binding posts, or other terminal hardware, for connection to the • Metal box • 12 Vlight bulb, 25 W • Lamp socket A bridge rectifier packis highly recommended over constructing a bridge rectifier circuit from individual A larger capacitor value is fine to use in this experiment so long as its working voltage is high enough. To be safe, choose a capacitor with a working voltage rating of at least twice the High-wattage 12 V lamps may be purchased from a recreational vehicle (RV) and boating supply store. Common sizes are 25 and 50 W. This lamp will be used as a heavyload for the power supply.
