摘要： A current sense system includes a current transformer having a primary coil and a secondary coil, wherein the secondary coil has a first and second terminal; a burden resistor connected between the first terminal of the secondary coil and ground; a monitor circuit that measures current in the primary coil by monitoring voltage across the burden resistor; and a built-in test (BIT) circuit connected to the second terminal of the secondary coil. The BIT circuit provides a virtual ground during normal operation, and either a positive voltage or a negative voltage during test operations.

摘要： A current control system for controlling current provided to a load includes a current sensor that senses a current to the load; a first power switch selectively enabled to supply power to the load and disabled to prevent power from being supplied to the load; and a control circuit. The control circuit includes a comparator that compares the sensed current with a commanded current to determine whether to enable or disable the first power switch, and a timer circuit that prevents the power switch from being enabled by the comparator more than once within a predetermined time period.
