Abstract:
A shoot-through protection circuit including a first switch connected to a positive bus and connected to a first center node via a first electrical path, a second switch connected to a negative bus and connected to the first center node via a second electrical path, a circuitous third electrical path connecting the first center node to a first load output, a first magnetic core surrounding the first electrical path and the circuitous third electrical path, a second magnetic core surrounding the second electrical path and the circuitous third electrical path, and wherein a polarity of one of the first electrical path and the second electrical path is aligned with a polarity of the circuitous third electrical path within the corresponding one of the first magnetic core and the second magnetic core and a polarity of the other of the first electrical path and the second electrical path opposes the polarity of the circuitous third electrical path within the corresponding one of the first magnetic core and the second magnetic core.
