How an SCR works?-Principle of Operation SCR Working Principle The SCR is a four-layer‚ three-junction and a three-terminal device and is shown in fig.a. The end P-region is the anode‚ the end N-region is the cathode and the inner P-region is the gate. The anode to cathode is connected in series with the load circuit. Essentially the device is a switch. Ideally it remains off (voltage blocking state)‚ or appears to have an infinite impedance until both the anode and gate terminals have suitable

an engine and then go into detail about how all the pieces fit together‚ what can go wrong and how to increase performance. The purpose of a gasoline car engine is to convert gasoline into motion so that your car can move. Currently the easiest way to create motion from gasoline is to burn the gasoline inside an engine. Therefore‚ a car engine is an internal combustion engine -- combustion takes place internally. Two things to note: There are different kinds of internal combustion engines.
