Abstract
This application discloses an electrical system and an electrical apparatus. The electrical system includes: a first-stage conversion module including a plurality of first controllable switches; a second-stage conversion module including a plurality of second controllable switches; a first digital signal processor configured to control the first controllable switch; and a second digital signal processor configured to control the second controllable switch, where a first output crossbar switch of the first digital signal processor is configured to supply a first internal signal to a first output port, so that the second digital signal processor receives the first internal signal within a preset time through a second input port. The internal signal of the first digital signal processor can be enabled to be transmitted to the second digital signal processor within a relatively short time, thereby reducing a time interval for triggering a protection action between the two digital signal processors.
