Mosfet shoot through
WebAvoiding static shoot-through is fairly simple: just make sure you never close both ‘a’ or ‘b’-side FETs at the same time. The bigger problem is dynamic shoot-through: when you turn one FET off, while turning the other FET on, for a short while both the low and high-side FETs are potentially conducting to a certain degree, creating a – relatively – low … WebDec 4, 2024 · Basically, the insight is that, a diode acts as a short circuit until it turns off, so what you intended as dead-time can actually result in shoot-through anyway because of the diodes. In that case, it is better to shoot through the MOSFETs (channel current) …
