Abstract
Description
Technical Field
[0001] This application relates to the field of power supply devices, and particularly to a UPS circuit device with energy-saving control. Background Art
[0002] An uninterruptible power supply, abbreviated as UPS (Uninterruptible Power Supply), is an uninterruptible power supply containing an energy storage device. The UPS can ensure that the load device can continue to work after a power outage. For example, a computer can continue to work for a period of time after a power outage to enable the user to save data urgently and avoid data loss. Currently, the output methods of widely used UPSs are divided into two types, usually bypass output or backup power output.
[0003] In the scenario of using a UPS, usually multiple load devices use one UPS, and the load devices are also divided into critical loads (main devices) and non-critical loads (slave devices). Non-critical load devices are related devices that play an auxiliary function for critical load devices. The relevance in the UPS circuit usually involves the following four aspects: functional dependence (non-critical loads (such as displays and printers) usually rely on critical loads (such as hosts) to function); power supply priority (in the case of limited power supply, such as when the UPS battery supplies power, the power demand of critical loads should be ensured first); energy management (non-critical loads such as displays and printers are still connected to the UPS output and continue to consume power, resulting in waste of energy); operation association (usually the critical load (such as the host) is turned on or off first, and then the non-critical load (such as the display and printer) is turned on or off as needed).
[0004] When a power outage occurs, the user uses the critical load device connected to the UPS according to the power supply priority. When the use is completed, turning off the critical load device can stop the electrical connection with the UPS, but the non-critical load devices that are functionally dependent on and operationally associated with the UPS and the critical load device will still consume power, causing waste of energy management.

[0040] Please refer to Figures 1 - 4 , the embodiment of the present application provides a UPS circuit device 1 for energy-saving control. The UPS circuit device 1 includes an input end 11 and an output end 12. The input end 11 is connected to the live wire, and the output end 12 is connected to the neutral wire. The UPS circuit device 1 further includes an output port 20 and an electronic switch 10. The output port 20 is used to connect an electrical appliance. In this embodiment, the electrical appliances include a backup power supply 2021, a main device 2031, and a slave device 2041.
[0041] The master device 2031 is a critical load, and the slave device 2041 is a non-inertial load. There is a functional dependency between the master device and the slave device. In this embodiment, the master device 2031 is a control device such as a computer. The slave device 2041 is an auxiliary device such as a printer or a scanner. In some feasible embodiments, the UPS circuit device 1 can also be provided with a parallel output port 20 to increase the connected devices for users to use.
[0042] In some feasible embodiments, the output port 20 can also be connected in series or in parallel with other electronic components. The electronic switch 10 is used to control the input voltage of the UPS circuit device 1 and the input terminal 11, the output voltage of the output terminal 12, and the disconnection and connection of the electrical appliance.
[0043] The output port 20 includes a first output port 201, a second output port 202, a third output port 203, and a fourth output port 204. In this embodiment, the first output port 201 is set as a bypass. When the input terminal 11 or the output terminal 12 fails or is under maintenance, the input terminal 11 and the output terminal 12 are bypassed to ensure the connectivity and normal operation of the UPS circuit device. The second output port 202 is provided with a backup power supply 2021 and is electrically connected to the backup power supply 2021. The backup power supply 2021 stabilizes the voltage of the backup power supply 2021 in a discharging or charging state through the first resistor 301. The third output port 203 is provided with the master device 2031 in an electrical connection relationship. The master device 2031 stabilizes the voltage supplied by the backup power supply 2021 in a discharging or charging state through the second resistor 302. The fourth output port 204 is provided with the slave device 2041 in an electrical connection relationship, and there is also an electrical parallel connection between the master device 2031 and the slave device 2041. In this embodiment, the master device 2031 can work alone or work in cooperation with the slave device 2041.
[0044] When the input terminal 11 is under normal power supply, the UPS circuit device 1 inputs voltage through the input terminal 11, and the devices electrically connected to the UPS circuit device 1 are under normal power supply for use. When the input terminal 11 is powered off, the UPS circuit device 1 outputs voltage through the bypass and uses the backup power supply 2021 to supply power to the electrical appliance. When the backup power supply 2021 is supplying power and the UPS circuit device 1 detects that the channel target value of the master device 2031 is less than the channel target value of the slave device 2041, the UPS circuit device 1 disconnects the voltage output of the backup power supply 2021 and the slave device 2041. When the UPS circuit device 10 detects that the channel target value of the master device 2031 is greater than the channel target value of the slave device 2041, the UPS circuit device 1 can self-start or start the slave device 2041 through the user to input voltage for use.
[0045] In this embodiment, the electronic switch 10 includes a first electronic switch 101, a second electronic switch 102, a third electronic switch 103, a fourth electronic switch 104, a fifth electronic switch 105, and a sixth electronic switch 106. In this embodiment, the electronic switches 10 involved are all relays.
[0046] In some feasible embodiments, the electronic switch 10 can also be set as other switches or electronic controllers, such as electronic components like programmable logic controllers (PLCs), electromagnetic contactors, etc. The following are embodiments of the UPS circuit device 1 under external power supply and internal power supply.
[0047] The first electronic switch 101 is set to be connected to the output terminal 12, the second electronic switch 102 is set to be connected to the input terminal 11, and the first electronic switch 101 and the second electronic switch 102 are provided with a first output port 201. The third electronic switch is set to be connected after the second electronic switch, the fourth electronic switch 104 is set after the third electronic switch 103, and both the third electronic switch 103 and the fourth electronic switch 104 are single-pole double-throw switches. The fifth electronic switch 105 is set to be connected after the fourth electronic switch 104, and the fifth electronic switch 105 controls the second output port 202 and the third output port 203, as well as the first resistor 301 and the second resistor 302. The sixth electronic switch 106 is set to be connected after the fifth electronic switch 105 and is used to control the fourth output port 204.
[0048] The first electronic switch 101 controls the path output voltage flowing out of the UPS circuit device 1. The second electronic switch 102 controls the input voltage flowing into the UPS circuit device 1 through the input terminal 11;. The first electronic switch 101 and the second electronic switch 102 are connected when the UPS circuit device 1 is operating. When the input terminal 11 is normally powered, the UPS circuit device 1 charges the backup power supply 2021 with the input voltage through the electronic switch 10. When the input terminal 11 is abnormally disconnected, the UPS circuit device 1 adjusts the voltage of the backup power supply 2021 through the resistor 301 through the electronic switch 10, so that the backup power supply 2021 is in the output voltage state.
[0049] When the input terminal 11 is normally powered, the backup power supply 2021 is in the charging state of the input voltage. When the input terminal 11 is abnormally disconnected, the UPS circuit device 1 adjusts the voltage through the resistor 302, so that the backup power supply 2021 is in the output state.
[0050] In this embodiment, the third electronic switch 103 includes a first contact 1031 and a second contact 1032. The fourth electronic switch 104 includes a third contact 1041 and a fourth contact 1042. When the UPS circuit device 1 is in the power supply state, and the second output port 202 and the third output port 203 are in the electrified state. When the input end 11 of the UPS device circuit 1 is powered off, power is supplied through the backup power supply 2021 controlled by the second output port 202. When the fifth electronic switch 105 is turned off, the second output port 202 and the third output port 203 are in the powered-off state.
[0051] A sixth electronic switch 106 is provided between the third output port 203 and the fourth output port 204; the sixth electronic switch 106 controls the voltage flowing through the fourth output port 204 of the UPS circuit device 1. When the sixth electronic switch 106 is turned on, the voltage flows through the fourth output port 204. When the sixth electronic switch 106 is turned off, there is no voltage flowing through the fourth output port 204.
[0052] The first embodiment is an embodiment of external power supply for the UPS circuit device 1. When the UPS circuit device 1 is normally powered by the input end 11 and the output end 12, the second electronic switch 102 connected to the input end 11 is turned on, the third electronic switch 103 is connected to the second contact 1032, the second contact 1032 is electrically connected to the fourth contact 1042, the fourth contact 1042 is connected to the fourth electronic switch 104, and the backup power supply 2021 is in the charging input state through the fifth electronic switch 105. And the channel target value of the main device 2031 provided at the third output port 203 and the fourth output port 204 is detected. When the channel target value of the main device 2031 is greater than the channel target value of the slave device 2041, the user can operate and use the main device 2031 and the slave device 2041 without affecting the user's use. The voltage forms a loop through the bypass of the first output port 201 through the first electronic switch 101 and is in a connected state.
[0053] When the input end 11 or the output end 12 is abnormal, and the second electronic switch 102 connected to the input end 11 is turned on, the third electronic switch 103 is connected to the first contact 1031, the first contact 1031 is electrically connected to the third contact 1041, the third contact 1041 is connected to the fourth electronic switch 104, and the backup power supply 2021 is in the discharge output state through the first resistor 301 through the fifth electronic switch 105. And the channel target value of the main device 2031 provided at the third output port 203 and the fourth output port 204 is detected. When the channel target value of the main device 2031 is greater than the channel target value of the slave device 2041, and the user has not completed saving data, the user can normally use the main device 2031 and the slave device 2041 by discharging the backup power supply 2021.
[0054] When the UPS circuit device 1 detects that the channel target value of the electrical signal of the master device 2031 is less than the channel target value of the slave device 2041 and the user does not use the master device 2031 for work, the UPS circuit device 1 disconnects the sixth electronic switch 106 and cuts off the power supply to the slave device 2041.
[0055] In the above embodiment, the UPS circuit device enables the connected bypass and electrical appliances to be powered normally or switched off through the path state between the input end and the output end. When the voltage at the input end or the output end of the UPS circuit device is abnormal, the UPS circuit device discharges using the backup power supply so that the connected devices can work normally. When the master device is working, the slave device can work synchronously with the master device. When the master device is not working, the slave device will stop the input voltage and stop working, so that when the UPS circuit device is connected to the input end 11 or powered by the backup power supply, the power consumption is reduced to avoid waste of resources.
[0056] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of this application. Thus, provided that these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
[0057] The above are only the preferred embodiments of the present invention, and of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
