Catalogued from PDF version of thesis. Includes bibliographical references (page 43). Switch is an electrical component that can turn on or off in an electrical circuit, interrupting the current or diverting it from one conductor to another. In power electronics sector hard switching and soft switching are mostly used switching scheme. Hard Switching is the commonly used method of switching. There are some obstacles in hard switching. When hard switching occurs it is very difficult to diminish the longing of voltage due to high frequency. Snubber circuits, RC circuits etc. can be used as the solution for this method of switching. Soft switching is the most efficient solution for this problem.. By utilizing up-to-date technology within MOSFETS’s, it is probable to decrease the switching loss. Hard switching is totally opposite to the soft switching. While using of soft switching circuits, at first it is begun with hard switching circuit and then supplement sub circuit to (power component) make it to use a soft. Soft defines that to accomplish plane current /voltage conversions in the switching instant. In order to get smooth transitions, the major standard for all ‘Soft Switching’ techniques are to make switching in the time at zero current and zero voltage, in the main switching devices. Soft switching methods are used to get better efficiency and reduced switching pressure at high frequency. In the scheme of Zero-Voltage Switching (ZVS) before turning on the voltage across the device is zero. Instead, in Zero-Current Switching (ZCS), before turn off the current over device is zero just. By simulating circuits, it can be found that in soft switching, reduction of switching loss happens. This will give more appropriate result for using soft switching. In this thesis soft switching process is done by the application of resonant converter circuits. Using soft switching. In this thesis soft switching process is done by the application of resonant converter circuits. Mehedy Hachan Mehedy Md. Akib Hasan Zoardar Sayed Alvee Islam Shakil Ahmed B.
