Abstract
A circuit may include a switching element configured to draw a positive current from a source/sink unit when the switching element is turned on, the source/sink unit including an inductance, the inductance emitting an excess positive current after the switching element is turned off. Additionally, the circuit may include a snubber circuit configured to absorb the excess positive current from the inductance of the source/sink unit, and deliver a negative current to the source/sink unit. In one example, the delivered negative current has a lower amperage and a longer duration than the positive current.
