Abstract: A method for controlling a triode for alternating current (TRIAC), applied to a device, is provided. A voltage is connected to an anode of the TRIAC, and a scaled down voltage is fed into an analog-to-digital converter (ADC) pin of the device. The method includes (1) tracking the voltage at the anode of the TRIAC; (2) applying a trigger pulse to a gate of the TRIAC for a preset time based on the voltage at the anode of the TRIAC reaching a threshold; and (3) detecting whether there is a dip that corresponds to the preset time in the scaled down voltage at the ADC pin of the device. The method further includes, in response to not detecting a dip corresponding to the preset time in the scaled down voltage at the ADC pin, (4) waiting an amount of time; and (5) repeating the steps (1)-(3).

Abstract: Methods and systems provide an indication that a loose connection and/or fault occurred in a breaker box or other electrical connecting device. The method includes calculating normal resistance for circuits within a breaker box when a current drawing load is present, and monitoring increases in voltage drop of the circuits to detect whether the increase is due to increased current flow or a faulty connection.

Abstract: Poor opening is detected with certainty and reliability with respect to a ground line of an integrated circuit device regardless of the connection state of a load and the operating state of a drive circuit. In an integrated circuit device 10, a drive circuit 30 switches between conduction and interruption of a load current using switch elements 40 and 45. The ground line 31 is grounded via the GND terminal 32 to the common ground provided outside the integrated circuit device 10 and is connected to the drive circuit 30. The ground line 21 is grounded to the common ground via the GND terminal 22 and is connected to the control circuit 20. The diagnostic current supply circuit 90 supplies a predetermined diagnostic current to the ground line 31. The rectifying elements 61 and 62 are connected between the ground line 21 and the ground line 31. The diagnostic circuit 70 measures the potential difference between the ground line 31 and the ground line 21 and compares the potential difference with the predetermined comparison voltage 73 to diagnose the grounding state of the ground line 31.

Abstract: A power control device configured for diagnosing an open-circuit fault occurring in a power system of an autonomous vehicle and an open-circuit diagnosis method thereof, may include a power control switch that selectively connects or separates main power output from the first power supply and auxiliary power output from the second power supply, and a processor that determines a possibility of an open-circuit fault of a vehicle power source based on a current flowing through the power control switch and determines whether it is possible to drive an electric load with an output power of the second power supply alone and determine an open-circuit position based on an output of the first power supply when there is the possibility of the open-circuit fault.

Abstract: The present disclosure is directed to methods and apparatus that may collect information relating to a group of electrical power distribution wires, commonly referred to as an electrical branch circuit. Such methods can controllably cause a circuit breaker to open (clear) while keeping the branch circuit loaded within a predetermined set of parameters or specifications. Apparatus consistent with the present disclosure may use multiple high power resistive elements of different resistance values that are selectively connected to the branch circuit in a manner that provides a configurable limit to an available fault current when data relating to the branch circuit are collected and evaluated. Such methods can provide a positive indication to an electrician that allows the electrician to know that a particular electrical circuit has been de-energized before the electrician works on that particular electrical circuit.
