This study proposes an online dead time controller that utilizes in situ measurements from the power electronic application. To achieve this, the controller evaluates the steepness of the switch node voltage, leveraging the fact that the maximum steepness increases during hard switching. The proposed algorithm utilizes this dependency independently of system characteristics, thereby eliminating the need for preliminary training.
