Abstract
Methods and systems for arc detection are described. A controller can receive a bus voltage of a direct current (DC) bus connected to an energy source. The controller can determine whether the received bus voltage is less than a bus voltage threshold. The controller can, in response to determining the received bus voltage being less than the bus voltage threshold, determine an occurrence of an arc event in an apparatus that includes the DC bus and the energy source.
