  • Current sense components failure detection in a multi-phase power system
    Patent number: 7116239
    Abstract: An evaluator (210) having an input (207) for receiving a signal indicative of a channel current sensed via a sensor in a mutlichannel current sharing system, and circuitry (313, 319) coupled to the input (207) and responsive to the signal for indicating an unreliable sensing for the sensor when a low current condition occurs for a time period exceeding the switching time period of the channel current. Further, the apparatus can include an additional input (207) and circuitry (313, 319) for evaluating an additional sensor sensing an additional channel current. The low current condition is characterized by thresholds corresponding to the peak level and a valley level of the channel current over a switching time period.
