| 摘要: |
| 集成门极换流晶闸管(IGCT)在中压领域的应用越来越广泛。利用PSpice软件包建立了IGCT的单2T-3R模型仿真电路，并基于此模型对中压变频器中的逆变单元，在载波频率为800Hz时的三种情况(不考虑线路杂散电感、考虑较大杂散电感、考虑一种故障情况)进行了仿真和分析。提出IGCT不安装关断吸收电路只是在线路结构紧凑、杂散电感较小的场合：否则要加装关断吸收电路。 |

| Abstract: |
| IGCT(Integrated Gate Commutated Thyristor) is widely used in mid-voltage field. A single 2T - 3R simulation model of IGCT is established with PSpice(Personal Simulation program with IC emphasis). Based on it,an inverter unit of mid-voltage frequency converter is simulated and analy-zed at 800 Hz. Three conditions are involved:no line stray inductances,large stray inductances and accident. It is pointed out that the turn-off absorption circuit is unnecessary only in conditions of compact line structure and small stray inductances. |
