【Abstract】 Owing to the great performance of IGCT (Integrated Gate Commutated Thyristor), Much attention has been paid to it. In the thesis, IGCT which is suitable for simulation in High-voltage inverters is studied. According the main physical characteristic of IGCT (especially anode current and terminal voltage), its equivalent model is realized by the simulation tool of PSIM package. The strongpoint of simulated model is high speed and easy parameter design. It also describes the testing circuit of IGCT in the paper and experiment is accomplished on the basis of the parameter of ABB’S 5SHY35L4510 IGCT. According to comparing simulated waves with experimented waves, It show that the model has referenced sense and practicability.更多还原
