New description: ~ [New technical field] This creation is about a fan system and its soft start module. [Prior Art] With the development of technology, the higher the functional requirements of electronic devices, the higher the number and concentration of electro-subtrees used, and the relative heat dissipation requirements are also paper, so the heat dissipation function will be good or bad. It will directly affect the reliability and service life of electronic equipment. • The fan as a heat sink is a common structural setup. When used on the customer's system side, it usually increases or decreases the number of fans according to the different needs of the client, and drives and controls the fan system through the control device or control chip.

Each of the heat exchange elements 111 transmits a main power signal S01 to drive a motor (not shown) of each fan module 12. In addition, each fan module U is configured to receive an external pulse width modulation signal S (> 2 to change the rotation speed of the motor according to the pulse width S02. In general, the fan system 1 must be provided in any state. The customer system side SB is sufficient for the heat dissipation requirement of the M323166. Therefore, when one of the fan modules 12 of the fan system 1 is damaged, the hot swapping element 111 can be used to instantly replace the new fan by hot-swap. In order to maintain the heat dissipation requirement of the customer system SB. Since the motor of each fan module 12 is a dynamic inductive load, it takes a large starting current to start from a standstill state to a steady state, and the fan system 1 starts up. The moment, the system may generate an inrush current, a voltage spike (v〇ltagespike) or a surge noise (spiken〇ise) between the fan system 1 and the client system SB, and even generate a jump fire. The phenomenon, that is, the electric arc, causes damage to the customer system end SB or the fan system. In addition, while the fan module 12 is hot-swapped, the positive or negative glitch noise generated by each hot-swapping component lu Through the customer system The ground loop of the SB damages the small signal electronic components of the fan system 1 (® not shown), thereby reducing the quality of the wind system. 爰 Because of this, 'how to provide - when the fan system is started' can be effective (4) The generation of wave current, voltage or surge noise, and the fan system that achieves self-protection and its soft-start circuit module have become one of the important topics. [New content] -#In view of the above-mentioned subject' The purpose is to provide a fan system and its soft-start circuit module that can effectively suppress the generation of ship current, voltage spike or glitch noise when the wind material is started, and then achieve self-protection.

The selection unit is electrically connected and received with the power input terminal and the control unit respectively. According to the control signal, whether to transmit the power signal is selected. The fan module is connected to the soft start circuit module and has a motor. When the selection unit transmits the power signal to the fan module, the fan module is based on the power signal. To start the motor. According to the above description, a fan system and a soft start circuit module thereof are designed to generate a control signal after a predetermined time according to a power signal, and the selection unit transmits a power signal according to the control signal to The fan module is used to start the motor. Compared with the prior art, the present invention utilizes a soft start circuit module, and after the power input end receives the power signal, the control unit of the soft start circuit module generates a control signal after a preset time to control the soft. The selection unit of the startup circuit module transmits a power signal to activate the motor of the fan module. In this way, not only can the soft start circuit module be used as the function of the start fan module, but also the control unit of the soft start circuit module can effectively suppress the power input signal from the power input terminal to the fan module, and the power signal is The voltage spike M323166 (voltage spike) or surge current (inmsh CUrrent) generated by the fan module end and the spike noise generated by the start of the fan module.

Here, the power signal su is used as a voltage signal, and is provided by the client system 3 as an example. Referring to the soft start circuit module 21 shown in FIG. 3, in the embodiment, the control unit 212 is electrically connected to the selection unit 213, and generates a control JK No. S12 control unit after a preset time elapses. The 212 series has a first diode d-a first capacitor [I, a pole body d2, a first resistor R1 and a second resistor R2. The one end of the first pole body dl is electrically connected to the power input end 211 to receive the power signal M323166. The one end of the electric grid state C1 is electrically connected to the other end of the first diode dl to receive the power. GfL No. S11. One end of the second diode d2 is electrically connected to the other end of the first capacitor ci, and the other end thereof is grounded. One end of the first resistor R1 is electrically connected to the other end of the first diode d2 to receive the power signal S11, and the other end thereof is grounded together with the second diode d2. One end of the second resistor R2 is connected to another power of the first capacitor α, and generates a control signal S12, the other end of which is grounded together with the first resistor ri and the second diode d2. In the present embodiment, the first diode dl is used to ensure that the power signal S11 is reversely input to the power input terminal 211, and the second diode d2 is used to prevent the control signal S12 from flowing back. The length of the preset time in this embodiment corresponds to the length of the charging time of the first capacitor C1 by the power supply 峨su, and the charging time is determined by the difference in the capacitance value of the first capacitor C1. Therefore, the first capacitor α of different capacitance values can be changed according to different wires, so as to change the length of the preset time. #然 can also directly control the input time of the power to control the length of the preset coffee. Therefore, the electric dance C1 _ is characterized by its charge and discharge, and the voltage signal sii is input to the power input terminal 211 to suppress the voltage spike and the soup wave current to a minimum. The lion material 213 of the embodiment has a transistor Q1, and the transistor φ has a -first end G, a second end D and a third end s, and the implemented transistor can be a field effect transistor ( M〇SFET) 'The first-end G is __, the second end d is - the dipole and the third end S is a source. In this embodiment, the first end G is electrically connected to the control unit 212 to receive the control signal S12, and the second end D is electrically connected to the power input terminal 2 to receive the power signal S1 and the third end S system.
