Abstract: A method of providing diagnostic information for an electromagnetic latch assembly (122) includes providing a pulse to a circuit (200) that include one or more electromagnetic latch assemblies. The circuit (200) includes coils (199) of the electromagnetic latch assemblies. Each coil is inductively coupled with an armature (131) that is mechanically coupled to a latch pin (118). The circuit (200) is pulsed and a DC current in the circuit (200) that results from the pulse is measured over a first interval to determine a primary response. The current in the circuit (200) over a second interval is measured to determine a reference response. A second pulse may be used to generate the current for the reference response. The primary response and the reference response are compared to provide diagnostic information relating to position or movement of one or more of the latch pins (118).

Abstract: An electronic device is configured to be coupled to a capacitor bank in a power system network. The electronic device includes a first switch, a second switch, and a damping circuit in series with the second switch. The damping circuit includes a passive damping circuit and a thyristor that is in parallel with the passive damping circuit. Related methods and circuits are also described.
