Model Three-Phase PMSM Drive : how can i replace the IGBT devices with the more detailed N-Channel IGBT block

In the documentation ,Three-Phase PMSM Drive said N-Channel IGBT block can replace the IGBT devices ,but i can not connect the gate terminal of the N-Channel IGBT

Hi Yujian,

Thanks for your question.

The N-Channel IGBT block is a not an ideal switch block. It does require the use of a gate driver block to capture the non-linear turn on and turn off dynamics happening on the gate of the transistor.

Once you add a gate driver block from the library, you can connect the physical signal to the gate driver which then can be connected to the gate of the N-Channel IGBT block. See below.
