- 3. ABSTRACT Modern electrical equipment has a low DC output voltage. The alternating current utility supply must be converted and stepped down to a sufficient DC voltage. Previously, converters were enormous in size and cost a lot of money. The discovery of the switch mode power supply enabled a significant decrease in size and cost. This aim is achieved via increasing power density, which is accomplished by reducing the size of passive/energy storage components such as inductors, capacitors, and transformers. For better usage of existing electric energy, the complete power system should be run at high efficiency, which is why numerous types of converters are currently used. The research of AC-DC converters is carried out in this thesis, together with necessary simulations, to achieve a greater grasp of the issue. As a result, the primary goal of this research is to thoroughly investigate the working principles and applications of linear power supply in ac to dc converters
- 4. At present time there is an increasing demand for efficient systems every time we communicate approximately electricity consumptions and so as to keep up with those needs engineers were coming forward growing efficient conversion strategies and additionally been capable of design circuits with excessive performance. Nevertheless, technology on this discipline remains improving with facing new demanding situations. Converter in power electronics converts power from one type to another by means of various the voltage or frequency. Power conversion is based on kind of the input and output power. Converter driven programs are broadly used. The electrical power conversion is an exceptional field of electrical engineering. INTRODUCTION
- 5. OBJECTIVES AC-DC converters are electrical circuits that transform alternating current (AC) input into direct current (DC) output. They are used in power electronic applications where the power input a 50Hz or 60Hz sine-wave AC voltage that requires power conversion for a DC output. We utilize control electronic converters in our day-by-day life
- 6. COMPONENTS REQUIRED • 1. Transformer with 1A 12V Rating • 2. 4 pcs 1N4007Diodes • 3. 470uF & 220uF Electrolyticcapacitor. • 4. LDO or a Linear VoltageRegulator as per
- 8. CIRCUIT EXPLANATION From the circuit diagram, we can see the input from AC voltage coming from transformer and the output is from DC voltage source. A capacitor C3= 470 µF is attached to store charge. Here we use oscilloscope for measuring the graph of AC input and DC output. We get output of DC voltage= +12V.
- 10. BLOCK DIAGRAM SUMMARY To bias all electronic circuits, a DC power source is necessary. Depending on the electronic application, the DC output Vo will typically be in the 3-24V range. The diode is highly beneficial in this case since the properties of a silicon diode are non-linear, which means that current occurs for one voltage polarity but is zero for the opposite polarity
- 11. CONCLUSION AC to DC convert by using full bridge rectifier with different combination of load and observed the DC outcomes through simulations. We also studied about different types and application of AC-DC converters , keeping our main focus on single phase with full bridge rectifier converter circuits. We gained vast knowledge about PROTEUS software during the project, where we carried out all our circuit construction and simulation respectively. The main function is to have a good conversion
- 12. RESULT An AC source where AC voltageis given 220V and Frequency is 50Hz. Here, a transformer is attached with AC source which will transform 220v and make it a low voltageAC wave as AC voltagehas positive (+Ve) and negative (-Ve) terminals. Here, after step down to a smaller voltage we need to stop polarity changes. To make electrons pass onlyin one direction we need diodes. Here we are using 4 diodes as a bridge so that a positive and negative cycle will convert into a positive cycle where lower waves are lifted and make the wave as one directional.From Fig 14 we can see the output result of the sinusoidal wave when attached with a Full Bridge Rectifier.
