Electronic – How dead time happens in boost converter

boostbuckdc/dc converter

I understand that in a buck converter dead time happens as both switches are ON simultaneously and this short the power supply. However, I don't see how dead time can exist in boost converter. Could anyone explain it?

In your schematic, if S1 and S2 are closed the power supply still cannot be shorted. However, the capacitor C would short. The peak current might be high enough to damage your switching mechanism. So dead time is probably still a good idea.
