Memory short detection systems and methods include a power supply system with first power rail. A memory system includes a memory device connector that is configured to couple to a memory device and includes a first pin that is coupled to the first power rail and a second pin located adjacent the first pin. A short detection circuit is coupled to the first pin. The short detection circuit is configured to provide a first voltage from the first power rail, compare the first voltage to a first short detection voltage, and determine whether a short exists across the first pin and the second pin based on the comparing of the first voltage to the first short detection voltage. If a short is determined to exist across the first pin and the second pin, power is prevented from being provided to the memory device connector.

Electrical current sensing and monitoring methods include connecting sensing a voltage across a conductor having a non-linear resistance such as a fuse element. The current flowing in the conductor is calculated based on at least a first detected state of the sensed voltage and a thermal equilibrium characterization of the conductor.

Electrical current sensing and monitoring methods include connecting a compensation circuit across a conductor having a non-linear resistance such as a fuse element. The compensation circuit injects a current or voltage to the conductor that allows the resistance of the conductor to be determined. The current flowing in the conductor can be calculated based on a sensed voltage across the conductor once the resistance of the conductor has been determined.

Such systems and methods include a one or more power transistors that each have a respective die surface over which is positioned and electrically coupled to a conductive overlay. A temperature sensor is physically bonded to a top surface of the conductive overlay to provide a direct temperature measurement for the one or more power transistors.

A high-frequency resistant ground fault circuit interrupter (HF-GFCI) with self-test and end-of-life detection is disclosed. The invention incorporates a noise-resistant fault detection circuit, an auto-test module, and an end-of-life shutdown mechanism to ensure reliable protection. The device minimizes false tripping due to high-frequency noise and enhances safety through continuous self-monitoring. Experimental validation confirms improved immunity to leakage currents and transient voltage disturbances. The HF-GFCI also provides an LED circuit having dual functionality: an LED indicator circuit and neutral to ground detection on the load side of the HF-GFCI.

A current interruption system may include an electromechanical switch coupling an electrical source and an electrical load along an electrical line of a power delivery system. The current interruption system may also include a controller that may receive an indication of an electrical characteristic along the electrical line, determine a fault condition based on the electrical characteristic, and transmit instructions to interrupt a first current through the electromechanical switch according to a first mode or second mode based on the electrical characteristic and the determination of the fault condition. Additionally, the current interruption system may include a voltage source converter (VSC) that may receive the instructions from the controller, interrupt the first current according to the first mode or the second mode, and reduce a second current through the VSC to zero.

A leakage current detection and interruption (LCDI) device includes a leakage current detection module, including first and second leakage current detection lines, a signal line, and at least one resistive element and/or at least one semiconductor element, configured to detect a leakage current signal on the first or second current-carrying line and to generate a leakage fault signal in response thereto. The first and second leakage current detection lines are electrically insulated from each other, and respectively cover one of the first and second current-carrying lines. A point at which the first and second leakage current detection lines are coupled to each other is coupled to the signal line, to form respective current paths with the signal line, for detecting an open circuit fault in the leakage current detection module. The at least one resistive element and/or the at least one semiconductor element is coupled in the current paths.
