Description

Redundant power system to reduce standby power consumption

technical field

The utility model relates to a redundant power supply system, in particular to a redundant power supply system which reduces standby energy consumption.

Background technique

ATX (Advanced Technology Extended) is the most commonly used motherboard specification today, and a power supply implemented under the ATX specification will not be directly connected to a startup switch of the information system, but is actually connected to a power supply through a motherboard. It will start only after triggering, and the power supply normally supplies a standing power (commonly known as 5Vsb) to the main board, so that the main board has power at any time and enters the state of standby start. When the start switch is triggered by the user, the main board outputs a start signal to the power supply, so that the power supply uses the standing power as the start power to complete the work required for the normal operation of the start output of the main board Power, the so-called working power is 12V, 5V and 3.3V in the ATX power supply specification.

Furthermore, due to the requirements of the current technology industry for the stability of power supply, some operators have proposed a redundant power supply system (Redundant Power Supply), and the so-called redundant power supply system mainly includes at least two power supply modules and a connection The power integration backplane of these power supply modules, when supplying power, the power integration backplane determines the output power of each power supply module according to the energy consumption state of the connected load, that is, the energy consumption required by the load It is shared by these power supply modules. If one of the power supply modules is damaged and cannot supply power normally, the maintenance personnel can directly separate the damaged one of the power supply modules from the power integration backplane while the redundant power supply system is still in power supply, and replace another function Normal power supply module. However, the power supply modules used in the redundant power supply system can be regarded as a power supply respectively. In addition to supplying the working power required by the motherboard, it also converts and outputs the standing power, but the load operates According to different energy consumption, working power of different power and the standing power will be required. For example, the redundant power supply system has 4 sets of power supply modules, and each power supply module normally outputs 1W of the standing power, but the load only needs the 1W of the standing power, and the unused 3W of standing power becomes waste energy , and then consumed by other components. That is to say, the current redundant power supply system does not adjust the power of the standby power supplied by the redundant power supply system according to the energy consumption required by the load, thus generating many unnecessary losses.

Detailed ways

Related to the detailed description and technical contents of the present utility model, it is now described as follows with respect to coordinating drawings:

Please refer to Figure 1, as shown in the figure, the redundant power supply system for reducing standby energy consumption of the present invention is mainly composed of a plurality of power supply modules 1 and a power integrated backplane 2, and the present invention is here Two power supply modules 1 are used as an example, that is, a redundant power supply system of 1U specification called in the industry for illustration, but in fact, the number of these power supply modules 1 included in the redundant power supply system may vary depending on the implementation To adjust the quantity of these power supply modules 1 accordingly. To further explain, each of the power supply modules 1 included in the redundant power supply system of the present invention is independently connected to an external power supply 3, and receives an external power from the external power supply 3, and the external power supply 3 can be a room distribution power supply or an industrial power supply. Each of the power supply modules 1 has a working power modulation unit 11 and a standing power modulation unit 12 respectively, the working power modulation unit 11 and the standing power modulation unit 12 are respectively connected to the external power supply 3 and receive the external power, and the The working power modulation unit 11 further performs power modulation on the external power to output a working power, and the standing power modulation unit 12 performs power modulation on the external power to output a standing power, and the so-called working power is the ATX motherboard 12Vdc, 3.3Vdc or 5Vdc specified in the specification, the standing power is 5Vsb specified in the ATX motherboard specification. Further, each working power modulation unit 11 of each power supply module 1 of the present invention includes a rectification and filtering unit 111 connected to the external power supply 3, a power factor correction unit 112 connected to the rectification and filtering unit 111, a A transformer 113 , a pulse width control unit 114 , a switch element 115 and a modulation output unit 116 . The working power modulation unit 11 first uses the rectification and filtering unit 111 to rectify and filter the external power, and then uses the power factor correction unit 112 to adjust the power factor of the external power with a voltage adjustment level, and the pulse width control The unit 114 outputs a drive signal to determine the duty cycle of the switch element 115, and the coil current of the transformer 113 is modulated by the periodic turn-on and cut-off of the switch element 115, and the power output to the transformer by the modulation output unit 116 Modulation is performed, and finally the working power is output. Moreover, it can be known from the above that the standing power modulation unit 12 of the present invention also modulates the external power. In fact, the standing power modulation unit 12 can be a step-down power conversion module. Voltage conversion converts the external power to the standby power. Further, each power supply module 1 of the present invention also has a control unit 13 connected to the standing power modulation unit 12, and the control unit 13 can be set on the power supply path where the standing power modulation unit 12 is connected to the external power supply 3 above, and is triggered by a working signal to control the standing power modulation unit 12 to start or stop. When the control unit 13 stops the standing power modulation unit 12, it means that the standing power modulation unit 12 stops outputting the standing power; if the control unit 13 makes the standing power modulation unit 12 start, it means that the standing power modulation The unit 12 receives the external power, and performs power modulation on the external power to output the standing power.

Furthermore, the standby energy consumption management unit 22 of the present invention is connected with each control unit 13 of each power supply module 1 and controls each control unit 13 .

More specifically, assuming that the load 4 only needs the standing power of 1W in the standby state, and the redundant power supply system does not perform standby energy consumption management, the load 4 in the standby state normally supplies the 2W of the power. The standing power means that each power supply module 1 supplies the load 4 with the standing power of 1W. However, the standby energy consumption management unit 22 outputs the control signal to each of the control units 13 of each of the power supply modules 1 of the redundant power supply system according to the energy consumption of the load 4, so that one of the power The standby power modulation unit 12 of the supply module 1 continuously converts and outputs the standby power, and the other power supply module 1 stops converting and outputting the standby power, so that the power integration backplane 2 only outputs 1W of the standby power.
