Power-switching system for automatically adjusting voltage and method for automatically adjusting voltage via the power-switching system

摘要

A power-switching system for automatically adjusting voltage includes a power-switching module and a power-storing module. The power-switching module has one side electrically connected with a power source, and the power-switching module has a built-in memory unit. The power-storing module is electrically connected with the other side of the power-switching module, and the power-storing module has a firmware unit to provide a predetermined voltage message that the power-storing module needs. Whereby, when the memory unit reads the predetermined voltage message, an output voltage of the power-switching module is automatically adjusted. Moreover, when the power-switching module is used in a predetermined extraordinary status, the extraordinary status is transformed into an extraordinary digital code, and the extraordinary digital code is stored in the memory unit. Hence, designers or users will know what will occur when using the power-switching module when the extraordinary status occurs according to the extraordinary digital code.
