Abstract:
1. A transistor driven load circuit comprising: a gate driver transistor including an internal voltage clamp; a controller providing a gate control signal operable to control a state of said gate driver; a load connected to said gate driver, such that said gate driver allows power to flow through said load when said gate driver is in an on state and prevents power from flowing through said load when said gate driver is in an off state; a clamp assist circuit connected in electrical parallel to said load, wherein said clamp assist circuit is operable to dissipate energy flowing through said load during a high energy event in a recirculating device; and wherein the clamp assist circuit is a pulsed clamp assist circuit comprising a voltage divider operable to set an on threshold for a recirculating device and an oscillator circuit operable to pulse said recirculating device when said on threshold is exceeded.
