WebFor inverter circuits and the like, it is necessary to set an on-off timing “delay” (dead time) in order to prevent short circuits. During the dead time, both the upper and lower arms are in the “off” state. Basically, the dead time (seeFig.7-5) needs to be set longer than the IGBT … WebSnubber is a form of circuit protection against voltage spikes, ringing and oscillation effects. Snubber works by either clamping voltage spikes but not altering the ringing frequency or does the same function. Snubber Circuit Design …
