SCR Controller Description & Design | Hockey Puck SCR's | Control ... Representation of SCR and AC back to back switch3 Phase Scr Heater Wiring Diagram - Note: If you are not at all familiar with basic electronics, you might find it easier to understand this chapter if you read chapter 12 first. The pulsed devices mentioned so far have had moving parts but rotating or fluctuating magnetic fields can be created without moving parts.. A thermionic diode is a thermionic-valve device consisting of a sealed, evacuated glass or metal envelope containing two electrodes: a cathode and a plate.The cathode is either indirectly heated or directly heated.If indirect heating is employed, a heater is included in the envelope. In operation, the cathode is heated to red heat (800–1000 °C)..
