Title:
SWITCHING APPARATUS AND DC/DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2023/181633
Kind Code:
A1
Abstract:
In the present invention, a first transistor and a second transistor are connected in series to each other, the second transistor being provided on a side having a lower potential than the first transistor. On the basis of a change in the level of a drive control signal, the first transistor is turned on after a first delay time has elapsed, whereas the second transistor is turned off after a second delay time has elapsed. The turn-on timing of the first transistor and the turn-off timing of the second transistor are detected on the basis of a gate signal provided to the first and second transistors. The dead time is decreased by changing the first and/or second delay times on the basis of the difference between the timings.
