Abstract: A rapid shutdown system and a method for controlling the rapid shutdown system are provided. For each of shutdown devices in the rapid shutdown system, an electrical signal disturbance is applied to a direct current bus connected to the shutdown device at least once within each pre-shutdown period of the shutdown device, by an inverter in the rapid shutdown system operating in a mode of limited power output. Then, the shutdown device samples its input parameter and/or output parameter and determines, based on the sampled input parameter and/or the sampled output parameter, whether the electrical signal disturbance applied to the direct current bus meets a preset condition. The shutdown device switches itself on or remains in an ON state in response to a determination result that the electrical-signal disturbance already meets the preset condition.

Abstract: Provided in the present application is a micro inverter. In a main circuit of the micro inverter, after N conversion branches are cascaded with each other, the same transformer is shared to connect a secondary-side bridge arm, thereby avoiding the need for N transformers in the prior art; moreover, by means of cascading, the N conversion branches can realize decoupling in terms of control, thereby avoiding the need to additionally equip each branch with a device for decoupling, and thus reducing the volume and costs. In addition, each direct-current source or load can realize alternating-current grid connection only by means of one-stage conversion, and therefore, the conversion efficiency is improved compared with a two-stage conversion structure in the prior art.
