POWER SUPPLY SYSTEM AND POWER SUPPLY METHOD THEREOF

摘要

A power supply system and a power supply method thereof are disclosed. The power supply system includes a master power supply device and a slave power supply device. When a master power detection module detects that a current value of a master power signal generated from a master power supply module increases to a first loading proportion, a master micro-controlling module will notices a slave micro-controlling module via a controlling pin to enable a slave power supply module to generate a slave power signal. When a slave power detection module detects that a current value of the slave power signal decreases to a second loading proportion, the slave micro-control module will control the slave power supply module to stop generating the power signal.

1. A power supply system, used for outputting a total power signal, the power supply system comprising:
a master power supply device, comprising:
a master power supply module, used for providing a master power signal;a master micro-controlling module, electrically connected to the master power supply module, used for controlling the master power supply module;a master power detection module, electrically connected to the master power supply module, for detecting a current value of the master power signal; anda master current equalizing module, electrically connected to the master power supply module; and a slave power supply device, comprising:
a slave power supply module, used for providing a slave power signal;a slave micro-controlling module, electrically connected to the master micro-controlling module via a controlling pin, for controlling the slave power supply module;wherein when the master power detection module detects that the current value of the master power signal increases to a first loading proportion, the master micro-controlling module notices the slave micro-controlling module via the controlling pin, allowing the slave power supply module to provide the slave power signal;a slave power detection module, electrically connected to the slave power supply module, for detecting a current value of the slave power signal; wherein when the slave power detection module detects that the current value of the slave power signal decrease to a second loading proportion, the slave micro-controlling module controls the slave power supply module to stop providing the slave power signal; anda slave current equalizing module, electrically connected to the slave power supply module and the master current equalizing module; wherein the master current equalizing module and the slave current equalizing module are used for equalizing the current value of the master power signal and the current value of the slave power signal.
