Deadtime / Time Delay Generation

How to generate deadtime for power electronics application?

[KSKelvin]

In this post, you can find a deadtime symbol I created. This post include a discussion of different approach, including method from @marcos.uniovi. But if you only needs a fixed deadtime symbol, you can consider to just download Gate-DeadTime.qsym.

How to generate delay times between two signals?

This deadtime circuit is @marcos.uniovi design. The best answer may come from Prof. Alonso. From the waveform, what you can observe is that, you have input pulse with pulse width less than deadtime. This will mess the toggle sequence in this circuit with D flip-flop and therefore, you may get an output opposite to input over time. [image] I have another deadtime logic that don’t need a flip-flop, you can check if can handle this situation. But it is logic output, and you have to add E-sou…

I also have a number of power electronic subckt symbol that ready for simulation, you can download and try it out.
