摘要
针对6 kV/1 000 kW高压变频器中的IGCT保护电路进行仿真研究,在分析逆变器短路直通故障的基础上,选取一种利用快熔对IGCT进行保护的方案,针对IGCT的快熔保护电路作出了MATLAB仿真,通过仿真值与理论值相对比,结果证明选取的快熔能够对IGCT器件进行有效的保护.
Protection circuit for IGCT in 6 kV/1 000 kW HV inverter is studied.FUSE protection is selected for IGCT based on the analysis of the short circuit.The protection circuit is simulated by MATLAB.The simulation results show that the theoretical analysis is correct and the protection circuit is effective.
