US Patent 9502884 Methods and systems for protecting DC circuits

Methods and systems for protecting DC circuits are provided. In an aspect, a method for controlling at least one protection circuit is disclosed. The method can monitor one or more parameters of the at least one protection circuit. One or more control signals can be selectively provided to a plurality of switches in the at least one protection circuit based on one or more parameters of the at least one protection circuit, in order to implement the appropriate protective topology based on one or more parameters of the at least one protection circuit. The method can be used to control a plurality of switches in the protection circuit and protect the DC circuit against short circuit, instabilities, and bus outages, and the like.
