Patent ID: 7948730

Claim:
A fast turn-off and fast turn-on circuit for an interactive torque management clutch and control arrangement comprising: a first power source; at least one first switching device connected to said first power source for selectively connecting said first power source to portions of said circuit; a coil, wherein an electrical current from said at least one power source charges said coil and creates an electromagnetic field when said at least one switch is in a closed position and connects said at least one power source and said coil; a first voltage control device connected to said coil, wherein said first voltage control device limits a voltage in said circuit when said electromagnetic field decays; a second power source connected in parallel with said coil; a second switching device connected to said second power source for selectively connecting said second power source to portions of said circuit; an interactive torque management control unit containing said first power source, said at least one switching device, said second power source, and said at least one second switching device; and an interactive torque management clutch arrangement containing said coil and said first voltage control device.
