My recommendation would be to first get your IGBT circuit designed in a simulation program like LTspice, using ideal voltage sources (configured for PWM generation if necessary), and voltage/current sense points in the design. Post that circuit, and it'll be clearer wh...
为验证门极放电量对串联IGBT关断承压的影响及电流吸收电路的均压作用,本文给出基于LTSpice的两只IGBT串联仿真结果如图5所示,其仿真电路结构与图3一致,仿真元器件及其参数见表1及表2。 由图5a可以看出,没有电流吸收电路作用时,10ns的关断延时所造成的串联IGBT门极放电偏差Qdelay将引起798V的承压差。由于该情况下,下...
