#SCR Commutation #Basics of Power Electronics #Turning-OFF of scr is called commutation. A thyristor is a four layer 3 junction p-n-p-n semiconductor device consisting of at least three p-n junctions, functioning as an electrical switch for high power operations. It has three basic terminals, namely the anode, cathode and the gate mounted on the semiconductor layers of the device. The SCR or thyristor is one kind of semiconductor device and it is specially designed to utilize in high-power switching applications. The operating of this device can be done in a switching mode only and acts as a switch. #Power Electronics refers to the process of controlling the flow of current and voltage and converting it to a form that is suitable for user loads. The most desirable power electronic system is one whose efficiency and reliability is 100%. A power electronic system converts electrical energy from one form to another and ensures the following is achieved - Maximum efficiency Maximum reliability Maximum availability Minimum cost Least weight Small size. #1. https://youtu.be/UH85QDWm1eY #2. https://youtu.be/m7H_DNYeMbM #3. https://youtu.be/dr02dEpk2pQ # Thanks for watching. #VSK Entertainments
