WebUnfortunately keeping track of the electrons is the reverse of standard EE terminology (where "current" flows from positive to negative) but let's give it a shot. When we start CH has +1V, so the bottom plate has -1V worth of electrons more than the top plate. When CK goes low it injects some electrons. WebThis help to prevent the device from conducting large negative current, which in turn reduce its reverse recovery charge and reverse recovery time.
