Dead-time in Full Bridge Inverter (LTSpice Simulation)
Duty cycle shortener (winny's suggested name): -



The lower waveform in the picture above can be used for top-left and bottom-right switches. An inverted version of the middle waveform (use a NAND gate instead) can be used to activate top-right and bottom-left switches.


Choose logic gates that have schmitt trigger inputs.
Choose RC to give appropriate time delay in line with schmitt trigger input levels.
