PRACTICAL WORK:




DISCUSSION: This lab is related to how IGBT works as a switch. We can use an IGBT as a switch. By using an IGBT as a switch, we can automate the process of switching or switching on or off the load remotely operated instead of using an electromechanical switch that is operated by hand. While doing this experiment, we follow all the rules of the laboratory. First of all, we connect all equipment by following a circuit diagram. Then we connect all the equipment with the AC supply for our experiment. An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch, which, as it was developed, came to combine high efficiency and fast switching. We take all the values perfectly and put them on the table. We are very careful to take the value of voltages and currents. Sometimes multimeter was not capable to read the short-range value of current. So, we take an effective ammeter to measure the short range of the current value. Finally, we disconnect all the connections carefully and return the equipment to the lab assistant.
