| dc.description.abstract | The main objective of this project is to design dc converter or well-known as dc chopper for 5V, 10A application. The use of chopper circuit is to convert an unregulated dc voltage from the supply to the regulated dc voltage. The input voltage can be varied from 10V to 36V. Anyway, 10V input voltage has been choose. This project should be design with high efficiency which is 80%. By using the Pesim, analysis of chopper circuit has been made. This approach is used to determine whether the circuit was design correctly and having a good condition. Analysis has been made by varying the switching frequency which will result in good efficiency due to no power dissipated at switch used. When switch is use, control circuit is required to control the switch. In this project, PWM technique is used. It can switch the transistor very fast. That’s why this technique is used. In addition, this technique will ensure good performance. To ensure that the chopper circuit operated at high efficiency, the appropriate frequency should be determined. In this project, 20kHz frequency with 50us for each switching cycle have been choose. Power supply for chopper circuit is also designed. It contains a rectifier circuit which is function to convert ac voltage from the main power supply to dc voltage. The theory in power electronics are widely used in this project. | |
