The inability to adjust certain timing parameters directly in the IGBT block dialog box in Simscape Electrical might be due to the specific modeling options you have selected. You may refer to the below steps to address the same:
- Modeling Option: Use "Simplified I-V characteristics and event-based timing" for adjustable timing parameters and "Full I-V and capacitance characteristics" for detailed modeling.
- Adjusting Parameters: In the simplified model, adjust "Turn-off tail current transit time" under "Dynamics" and in the detailed model, adjust "Total forward transit time" under "Advanced" settings to simulate tail current.
- Simulating Tail Current: You may focus on using the N-Channel IGBT block with the "Full I-V and capacitance characteristics" option. The tail current can be controlled by adjusting the 'Total forward transit time' parameter, which is crucial for capturing the dynamic behavior during turn-off.
