Abstract
Some apparatus and associated methods relate to a three quarter bridge (TQB) applied across an output inductor of a buck-derived power converter, the TQB operated in a first mode such that when a high-side switch of the power converter is turned on, the TQB configured to pass a first controlled current to combine with a first output inductor current to a load, the TQB configured to control the first controlled current to minimize a negative voltage transient on the load, the TQB operated in a second mode such that when the high-side switch of the power converter is turned off the TQB configured to divert a second controlled current away from the load and to circulate the second controlled current through the output inductor, the TQB configured to control the second controlled current to minimize a positive voltage transient on the output of the power converter.
