ELECTRICAL SYSTEM AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/082108
Kind Code:
A1
Abstract:
The present application discloses an electrical system and an electrical device. The electrical system comprises: a pre-conversion module comprising a plurality of first controllable switches; a post-conversion module comprising a plurality of second controllable switches; a first digital signal processor used for controlling the first controllable switches; and a second digital signal processor used for controlling the second controllable switches. A first output crossbar switch of the first digital signal processor is configured to: provide 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 by means of a second input port. The first internal signal is a fault signal formed in the first digital signal processor. An internal signal of the first digital signal processor can be transmitted to the second digital signal processor within a short time, thereby reducing the time interval in triggering a protection action between the two digital signal processors.
