Detailed Description
The following describes in more detail embodiments of the present invention with reference to the schematic drawings. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to scale, which is intended merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Referring to fig. 1 and fig. 2, fig. 1 is a block diagram of a switching power supply system according to a preferred embodiment of the invention; fig. 2 is a flowchart of a switching power supply method according to a preferred embodiment of the invention. As shown in the figure, a switching power supply method is implemented by a switching power supply system 1, and includes the following steps S101 to S110.
The switching power supply system 1 is applied to a server system, and includes a power supply unit 11, a first monitoring protection chip 12, an electric energy integration circuit 13, a second monitoring protection chip 14, a third monitoring protection chip 15, at least one first functional module 16a,16b,16c (three schematic diagrams are drawn and marked), at least one second functional module 17a,17b,17c (three schematic diagrams are drawn and marked), and a plurality of fans 18 (three schematic diagrams are drawn and marked). It should be noted that the switching power supply system 1 is applied to a server system, and does not necessarily mean that the switching power supply system 1 is externally connected to the server system, and the switching power supply system 1 may be included in the server system.
The power supply unit 11 is electrically connected to the first monitoring protection chip 12 and the power integration circuit 13. The first monitoring protection chip 12 is electrically connected to the first functional modules 16a,16b,16 c. The power integration circuit 13 is electrically connected to the second monitoring protection chip 14 and the third monitoring protection chip 15. The second monitoring protection chip 14 is electrically connected to the fan 18. The third monitoring protection chip 15 is electrically connected to the second functional modules 17a,17b,17 c.
Step S101: whether the server system is in a power-off state.
Whether the server system is in a power-off state is determined, where the power-off state is the S5 state, that is, the server system is powered off and the plug is plugged into the socket, and this indicates that the server system is powered off but still receives the commercial power provided by the socket. When the result of step S101 is yes, go to step S102; if the result of step S101 is no, the process will again proceed to step S101.
Step S102: and providing standby power by using the power supply unit.
The power supply unit 11 provides a standby power when the server system is in a power-off state. The standby power, also called reserve power or standby power, refers to a power transmitted by the power supply unit 11 when the plug of the server system is plugged into the socket and is not turned on.
Step S103: and receiving standby power by using the power integration circuit.
The power integration circuit 13 receives standby power from the power supply unit 11 when the server system is in a power-off state.
Step S104: the third monitoring protection chip is used for receiving the standby electric energy and transmitting the standby electric energy to the second functional module, so that the second functional module receives the standby electric energy and operates.
The third monitoring protection chip 15 receives the standby power from the power integration circuit 13 and transmits the standby power to the second functional modules 17a,17b, and 17 c. Therefore, the second function module 17a,17b,17c can operate when the server system is in the power-off state. For example, the second functional module 17a may be a Baseboard Management Controller (BMC), the second functional module 17b may be a Complex Programmable Logic Device (CPLD), and the second functional module 17c may be other modules that need to operate in a shutdown state. In this embodiment, the third monitoring Protection chip 15 adopts an MP5023 chip for monitoring the Current flowing through and the power consumption, and has an Over Current Protection (OCP) function.
Step S105: the second monitoring protection chip is used for receiving the standby electric energy and transmitting the standby electric energy to the fan, so that the fan receives the standby electric energy and operates with standby power.
The second monitoring protection chip 14 receives the standby power from the power integration circuit 13 and transmits the standby power to the fan 18. Therefore, the fan 18 can be operated at standby power when the server system is in the off state. Since only the second functional modules 17a,17b, and 17c will normally operate when the server system is in the shutdown state, the fan 18 operating with the standby power can not only solve the heat dissipation requirement of the second functional modules 17a,17b, and 17c, but also avoid the problem of excessive waste of electric energy. In practice, the standby power of the fan 18 usually means that the duty ratio of the pwm is between 15% and 25%.
In this embodiment, the second monitoring Protection chip 14 may also adopt an MP5023 chip for monitoring the Current flowing through and the power consumption, and has an Over Current Protection (OCP) function.
Step S106: whether the server system is switched to the power-on state.
It is determined whether the server system is switched to the power-on state, which is the S0 state. If the result of step S106 is yes, indicating that the server system is in a normal operation state, i.e. all the components of the server system start to operate, then go to step S107; if the result of step S106 is no, the process will re-enter step S106.
Step S107: the power supply unit is used for additionally providing starting electric energy.
The power supply unit 11 additionally provides a power-on power when the server system is in the power-on state. The boot power, which may also be referred to as main power, normal power, or "real power" in the industry, refers to a power transmitted by the power supply unit 11 after the server system is booted.
Step S108: the first monitoring protection chip is used for receiving the starting-up electric energy and transmitting the starting-up electric energy to the first functional module, so that the first functional module receives the starting-up electric energy and operates.
When the server system is in the power-on state, the self-powered unit 11 receives power-on power from the first monitoring protection chip 12 and transmits the power-on power to the first functional modules 16a,16b, and 16 c. Therefore, the first functional module 16a,16b,16c will start to operate when the server system is in the power-on state. For example, the first functional Module 16a may be a Central Processing Unit (CPU), the first functional Module 16b may be a Dual In-line Memory Module (DIMM), and the first functional Module 16c may be another Module that starts to operate only when the computer is turned on.
In the present embodiment, the first monitoring Protection chip 12 adopts an ADM1278 chip to monitor the Current flowing through, power consumption, and has an Over Current Protection (OCP) function. Since the power of the power-on power is higher than the power of the standby power, the maximum current that the first monitoring protection chip 12 can bear is larger than the second monitoring protection chip 14 and the third monitoring protection chip 15.
Step S109: the power integration circuit is used for additionally receiving part of starting power.
The power integration circuit 13 additionally receives a portion of the power-on power from the power supply unit 11 when the server system is in the power-on state. At this time, the power integration circuit 13 still receives the standby power.
Step S110: the second monitoring protection chip is used for additionally receiving part of the starting-up electric energy and transmitting the starting-up electric energy to the fan, so that the fan receives the standby electric energy and part of the starting-up electric energy in the starting-up state and runs at normal power.
The second monitoring protection chip 14 receives part of the power-on power and the standby power from the power integration circuit 13 and transmits them to the fan 18. Therefore, the fan 18 can be raised to operate at a normal power higher than the standby power when the server system is in the on state. Because the first functional modules 16a,16b,16c and the second functional modules 17a,17b,17c all operate normally when the server system is in the power-on state, the fan 18 is raised to operate at normal power, which can solve the heat dissipation requirement for the first functional modules 16a,16b,16c and the second functional modules 17a,17b,17c to operate simultaneously. In practice, the normal power of the fan 18 usually means that the duty ratio of the pulse width modulation is at least 50%.
With the increasing heat dissipation requirement, the number of the fans 18 is also increasing, and therefore, the power integration circuit 13 additionally receives and transmits part of the power from the power supply unit 11, which also helps to increase the number of the fans 18 to operate at normal power. In practice, the power integration circuit 13 usually includes at least one Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) and can transmit standby power and part of the power-on power up to 50 amperes.
The second monitoring protection chip 14 is electrically connected to the power integration circuit 13 and the fan 18 individually, so that a power supply behavior separated from other modules (the first functional modules 16a,16b,16c and the second functional modules 17a,17b,17 c) can be achieved, and the problem that the other modules (the first monitoring protection chip 12, the third monitoring protection chip 15, the first functional modules 16a,16b,16c and the second functional modules 17a,17b,17 c) cannot operate due to abnormality is avoided.
In summary, the switching power supply system and the method thereof provided by the present invention utilize the power supply unit, the first monitoring protection chip, the power integration circuit, the second monitoring protection chip, the third monitoring protection chip, the first functional module, the second functional module and the fan, compared with the prior art, the present invention utilizes the third monitoring protection chip to enable the second functional module to operate in the shutdown state, utilizes the first monitoring protection chip to enable the first functional module to start to operate in the startup state, utilizes the second monitoring protection chip to electrically connect the fan, enables the power supply of the fan and other modules to be separated, and is not affected by other modules, and utilizes the power integration circuit to receive partial startup power, so that the fan can smoothly start to operate at normal power. In addition, the switching power supply system provided by the invention is more flexible in use and can be suitable for more different use requirements.
The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the scope of the claims.
