Abstract

The invention provides a fan system and a power reverse protection device thereof. The fan system is electrically connected with a power supply and comprises the power reverse protection device, a voltage regulator, a driver and a fan. The power reverse protection device is electrically connected with the power supply and comprises a voltage regulator switch and a starting device, wherein the voltage regulator switch receives an input signal from the power supply and determines a first output signal and outputs the first output signal; the starting device is electrically connected with the power supply and the voltage regulator switch, respectively receives the input signal and the first output signal, and determines whether to output a second output signal to the fan or not through the first output signal. The voltage regulator is electrically connected with the power supply, receives the input signal from the power supply, and outputs a regulation signal. The driver is electrically connected with the voltage regulator and is used for receiving the regulation signal and outputting a driving signal. The fan is respectively electrically connected with the driver and the power reverse protection device, respectively receives the driving signal and the second output signal, and operates according to the driving signal and the second output signal.

Description

technical field [0001] The invention relates to a fan system, in particular to a fan system which avoids reverse transmission of power supply signals and a power supply reverse protection device thereof. Background technique [0002] With the rapid development of science and technology, the higher the functional requirements for electronic equipment, the higher the number and integration of electronic components used, and the greater the power consumption demand of electronic equipment. Therefore, when the power consumption is large, Usually, a protection circuit is provided at the input end of the electronic device to protect the electronic device, and the performance of the protection circuit will directly affect the reliability and service life of the electronic device. [0003] At the input end of electronic equipment, it is a common structural setting to use the power reverse protection device to turn on the main power circuit in the electronic device and close the rema...
