    摘要: One embodiment relates to a control system. The control system includes a controller configured to drive a load based on a set-point of the load. The controller is also configured to measure a load characteristic of the load and compute an average load characteristic. The controller is further configured to determine a corrected set-point based on the computed average and to drive the load in response to the corrected set-point. Other systems and methods are also disclosed.

    摘要: A first and second node configured to couple to a load. A current source is adapted to drive a first current to the load through at least one of the first and second nodes. A first switch is coupled to the at least one of the first and second nodes. The first switch is adapted to interrupt the first current. A sense circuit is configured to monitor whether a second current is provided by the load after the first current is interrupted. The sense circuit provides an output that corresponds to a value of the second current and that indicates a type of the load.

    摘要: In one embodiment, a circuit can selectively adjust a current for driving a load. The circuit includes a sensor configured to measure a magnetic field associated with the current and provide a sensor voltage representative thereof. A control circuit is configured to selectively adjust the current as a function of the sensor voltage and a time-varying voltage threshold. Other methods and systems are also disclosed.

    摘要: One embodiment relates to a control system. In one embodiment, a control system is configured to drive a load based on a set-point of the load, a measured load characteristic and a supply voltage of the load. The controller is configured to determine a duty cycle based on the load characteristic, the set-point, and the supply voltage. The controller is further configured to drive the load in response to the duty cycle.
