The diode is a specialized electronic component with two electrodes called the anode and cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. Some diodes are made of metal electrodes in an evacuation chamber or filled with pure elemental gas under low pressure. Diodes can be used as rectifiers, signal selectors, voltage regulators, switches, signal modulators, signal mixers, signal extracts

For control purposes, the SCR is a regulated rectifier made from a silicon semiconductor material with a third terminal. Thanks to its high temperature and control capability, Silicon was chosen. In that a 3rd terminal called a gate decides whether the corrective transfer from open circuit, the basic feature of SCR vary from the usual 2-layer semi-circuit diode. b) 1. solid state relay can protect Control circuit From Electro motive Force Emf rather than EMR. 2. Solid state relay is faster th...
