Dead time & shoot-through prevention
Webthat features adaptive dead time and shoot-through protection. The adaptive dead time circuitry actively monitors the half-bridge outputs to minimize the time between high-side and low-side MOSFET transitions, thus maximizing power efficiency. Shoot-through protection circuitry prevents erroneous inputs and noise from turning both MOSFETS on … Webcases, shoot-through is generated during zero states. The zero and shoot-through states are spread over the switching period so that the number of higher harmonics in the transformer primary could be reduced[1].To reduce switching losses of the transistors, the number of shoot-through states per period is limited by two.
