Hi, I am trying to control an H bridge cell. So in order to avoid two swithes turn ON at the same time, I need to add the dead time. I would expect a similar waveform as below. Does anyone konw how to achieve this in Simulink? Thank you so much!

We now have the Gate Driver and Half-Bridge Drive blocks in Simscape™ Electrical™ which allow you to specify dead-time/blanking time in a numerically efficient way. Please see the screenshot below. Hope you find this solution useful.

Hi,
This is helpful, thanks. However, what kind of ports (or devices) should be connect to the output of Driver? I used Simulink-PS converter for the input, it can be connected. But, at the output, I used PS-Simulink converter and it cannot connected to Simulink signal MOSFET.

The output pins of the driver block should be directly connected to Simscape electrical ports on semiconductor device models in the Simscape Electrical library.

Add following blocks to your switching signal path and you can set the deadtime by setting the time delay of the transport dealy block.

Hello,
I tried this for my discrete time PWM model:
and it seems to be working alright:
you could even configure a variable delay in the "delay" block settings.
I hope that helps.

thanks, for solving my problem. by just adding transport delay block we can easyly add dead time control
