Abstract

See full text

A rapid shutdown system and a method for controlling the rapid shutdown system are provided. A disturbance is applied to a direct-current side of an inverter in the rapid shutdown system only when the inverter does not meet a starting condition, i.e., before the inverter starts. Once meeting the starting condition, the inverter normally operates. A shutdown device in the rapid shutdown system determines its state by determining whether the electrical signal at its output end meets the preset condition, and switches itself on or off in response to its determination.
