Abstract :
The current transport of transparent emitter is analysed in detail theoretically and the expression of the electron current density at the transparent anode is deduced. In addition, the switching characteristic of the gate commutated thyristor (GCT) device with transparent anode structure is simulated by using MEDICI simulator, and compared with the gate turn-off thyristor (GTO) device with conventional anode structure. The result shows that the theoretical analysis for the transparent emitter is reasonable. Based on theoretical analysis, the mechanism of the transparent emitter is revealed. The result provides an important design basis for the devices with the transparent emitter.
