Dead time & shoot-through prevention

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.
