ABSTRACT:
A circuit for discharging an inductive load of an H-bridge circuit at a controlled rate has been provided. When a first half of the H-bridge circuit is switched from a conductive state to a non-conductive state, the circuit clamps a first side of the inductive load, while creating a recirculation path to discharge the inductive load at a controlled rate.
A similar circuit may be utilized when a second (complementary) half of the H-bridge circuit is switched from a conductive state to a non-conductive state wherein the similar circuit clamps a second side of the inductive load, while creating a recirculation path to discharge the inductive load at a controlled rate.
