Abstract: Embodiments of the disclosure can include various electrical assemblies. In one embodiment, an electrical assembly can include a module including at least one module switching element and an energy storage device, the or each module switching element and the energy storage device in the module arranged to be combinable to selectively provide a voltage source; and a shorting device directly connected to first and second terminals of the energy storage device, the shorting device including a first shorting switching element configured to be switchable between: a first switching state to isolate the first and second terminals from each other; and a second switching state to electrically connect the first and second terminals to short the energy storage device.

Abstract: An electrical assembly comprises a plurality of modules (36), each module (36) including at least one switching element (38) and at least one energy storage device (40), the or each switching element (38) and the or each energy storage device (40) in each module (36) arranged to be combinable to selectively provide a voltage source, wherein each module (36) includes a respective sensor (46) that is configured to monitor at least one other of the plurality of modules (36), each sensor (46) configured to selectively detect an occurrence of an operational hazard in the or each corresponding monitored module (36).
