Abstract: An apparatus can include an inverter to provide an output N-phase alternating-current to an external component. When N equals two, a phase of the N phases can include an upper gate and a lower gate. The apparatus can also include a current detector configured to detect a phase current magnitude of the output alternating current. The apparatus can also include a controller coupled to the current detector and to the inverter. The controller can generate a gate command for controlling a gate of the inverter. The controller can also determine a value for a current threshold less than a shutoff current threshold for the external component. The controller can provide a protection command to turn off the upper gate of a corresponding phase of the inverter responsive to detecting that the phase current magnitude is greater than the current threshold.

Abstract: A method for processing an interphase short circuit is provided, including: when a two-phase or three-phase interphase short circuit occurs in a line, maintaining a fault phase of the line to be conducted and tripping off the remaining fault phases, and artificially grounding another fault phase connected to the fault phase or directly utilizing an existing grounding point; connecting a neutral point or a charged phase of a three-phase ineffectively grounded power supply system other than the fault phase to the ground, so as to form a closed loop with the fault phase and generate a current, and detecting a current duration by a controlled switch. When a certain controlled switch reaches a trigger condition and cuts off the line, a fault is cleared.

Abstract: An output module includes a first connection terminal, a second connection terminal, a power supply terminal, a controller, an output device, and a first cutoff switch. The first connection terminal is connected to a high potential side terminal of an external load. The second connection terminal is connected to a low potential side terminal of the external load. The power supply terminal is provided with an external power supply from an external power source. The output device is configured to operate by receiving a power supply generated by or based on the external power supply and to output an analog voltage or an analog current of a value instructed by the controller toward the first connection terminal. The first cutoff switch is configured to be controlled by the controller to open and close a first path between the second connection terminal and a ground.

Abstract: A direct current residual current protection device having a controlled current discharge having a positive and a negative input terminal, a positive and a negative output terminal, a first switch, a controller and a discharge control circuit. The first switch is interposed between the positive input terminal and the positive output terminal and operatively opens/closes an electrical connection between the positive input terminal and the positive output terminal. The controller has a current imbalance detection for a detection of a current imbalance between the positive and the negative output terminal. When the current imbalance is detected, the controller opens the first switch. The discharge control circuit is connected on one end between the first switch and the output terminal and on second end to both negative input and negative output terminal. The discharge circuit has a source of electrical energy that accumulates energy when the first switch is closed and discharges the accumulated energy when the first switch is opened.
