Description

Technical Field

[0001] The present invention relates to an uninterruptible power supply system and an operating method thereof, and in particular to an uninterruptible power supply system with a voltage dynamic adjustment function and an operating method thereof. Background Art

[0002] With the rapid development of the information industry, more and more critical load products (such as but not limited to servers, oxygen supply machines, etc.) have come out. These products usually have to operate continuously and avoid power interruptions as much as possible. Therefore, such products usually need to be equipped with an uninterruptible power supply system to continuously supply power to them to avoid power interruptions to such critical loads. Generally speaking, one end of the uninterruptible power supply system will be coupled to an AC power source such as the mains, or a stably provided DC power source, and the other end will be coupled to the critical load. The third end of the uninterruptible power supply system will be coupled to an energy storage element such as a battery, so that when the input power source such as AC or DC fails, the power supply of the energy storage element will be converted to supply the load to avoid power interruptions.

[0003] However, if a general UPS needs to supply power that meets the requirements of critical loads, it usually needs to be set separately. For example, assume that the input power is 19V, and the UPS must supply critical loads that require 19V power so that the critical loads can operate normally. Under this condition, when the input power fails, the UPS must also provide 19V power to enable the critical loads to operate stably. However, when the input power fails, if the UPS is to provide power with the same voltage value as the input power, the UPS must be set in advance. Whether it is written to the controller through the I / O interface, or adjusted by adjusting buttons, knobs, etc., the UPS can provide power with the same voltage value as the input power. Otherwise, if this adjustment method encounters the default value of the power provided by the UPS (for example but not limited to 12V) that does not meet the input power P1 (19V), the back-end critical load will fail due to receiving incorrect power, resulting in adverse consequences. Or, when changing critical loads that require different power, the UPS must be reset every time, causing inconvenience in use.

[0004] Therefore, how to design an uninterruptible power supply system and its operation method to have a voltage dynamic adjustment function and improve the convenience of use is a major topic that the present invention intends to study. Summary of the invention

[0005] In order to solve the above problems, the present invention provides an uninterruptible power supply system with dynamic voltage adjustment to overcome the problems of the prior art. Therefore, the uninterruptible power supply system of the present invention is coupled to at least one load, and the uninterruptible power supply system includes a bus, an input detection circuit, a plurality of battery modules, a conversion module and a controller. The bus includes an input end and at least one output end, the input end receives a first power source, and the output end is coupled to the load. The input detection circuit is coupled to the input end, and the input detection circuit detects the first power source to provide an input signal. The battery module can be respectively configured with a plurality of columnar cells, and the conversion module is coupled to the battery module and the bus to receive a plurality of battery power sources of the columnar cells. The controller is coupled to the input detection circuit and the conversion module, and when the controller determines that the first power source is normal through the input signal, the first power source is provided to the output end through the bus. Wherein, when the controller determines that the first power source fails through the input signal, the controller controls the conversion module to convert the battery power source into a second power source, and based on the requirements of the load, the controller controls the conversion module to adjust the second power source to be substantially equivalent to the first power source, so as to provide the second power source that meets the requirements of the load to the output end.

[0006] In order to solve the above problems, the present invention provides a voltage dynamic adjustment method for an uninterruptible power supply system to overcome the problems of the prior art. Therefore, the uninterruptible power supply system of the present invention is coupled to at least one load, and the uninterruptible power supply system includes a bus, an input detection circuit, a plurality of battery modules and a conversion module, and the operation method of the uninterruptible power supply system includes the following steps; (a) receiving a first power supply through the bus, and the input detection circuit detects the first power supply to provide an input signal. (b) judging that the first power supply is normal according to the input signal, providing the first power supply to the load through the bus. (c) judging that the first power supply fails according to the input signal, controlling the conversion module to convert the plurality of battery power supplies provided by the battery module into a second power supply. (d) according to the requirements of the load, controlling the conversion module to adjust the second power supply to be substantially equivalent to the first power supply, so as to provide the second power supply that meets the requirements of the load to the load.

[0007] The main purpose and effect of the present invention is that, since the uninterruptible power supply system of the present invention has the function of dynamically adjusting the voltage, the controller will control the conversion module to adjust the second power supply to be substantially equal to the first power supply based on the load demand, so as to provide the second power supply that meets the load demand to the output end. Therefore, the uninterruptible power supply system of the present invention will not cause the default power supply value of the uninterruptible power supply system to not meet the input power supply, so that the back-end critical load receives incorrect power supply and fails, or each time the critical load with different power demand is replaced, the uninterruptible power supply system must be reset, etc., so the effect of improving the convenience of use can be achieved.

[0073] The technical content and detailed description of the present invention are described below with reference to the accompanying drawings:

[0074] See also Figure 1The circuit structure diagram of the uninterruptible power system with voltage adjustment function of the present invention. The uninterruptible power system 100 receives the first power source P1 and is coupled to at least one load 200. The uninterruptible power system 100 includes a bus 1, an input detection circuit 2, a plurality of battery modules 3, a conversion module 4 and a controller 5, and the bus includes an input terminal 12 and at least one output terminal 14. The input terminal 12 receives the first power source P1, and at least one output terminal 14 is coupled to at least one load 200. The first power source P1 can be an AC or DC power source. When the first power source P1 is an AC power source, the input terminal 12 can also include a rectifier circuit or an AC / DC conversion circuit (not shown) to convert the AC first power source P1 into a DC power source. The input detection circuit 2 is coupled to the input terminal 12, and the input detection circuit 2 detects the first power source P1 to provide an input signal Si according to the first power source P1. It is worth mentioning that in one embodiment, the "power source" described in the present invention can be a general term for voltage, current and power. Furthermore, in one embodiment, the input detection circuit 2 may include a detection device such as a voltage detection circuit and a current sensor for detecting power supply.

[0075] The battery module 3 can be respectively configured with a plurality of columnar cells 32, and the conversion module 4 couples the battery module 3 and the bus 1. Each columnar cell 32 provides a battery power Pb to the conversion module 4, and the controller 5 couples the input detection circuit 2 and the conversion module 4 to control the conversion module 4 to convert the battery power Pb into the second power P2. When the controller 5 determines that the first power P1 is normal through the input signal Si, the first power P1 is provided to the output terminal 14 through the bus 1. When the controller 5 determines that the first power P1 fails through the input signal Si, the controller 5 controls the conversion module 4 to convert the battery power Pb into the second power P2.

[0076] Since the uninterruptible power supply system 100 of the present invention has the function of dynamically adjusting the voltage, the controller 5 will control the conversion module 4 to adjust the second power supply P2 to be substantially equal to the first power supply P1 based on the demand of the load 200, so as to provide the second power supply P2 that meets the demand of the load 200 to the output terminal 14. Therefore, the controller 5 of the present invention will actively control the conversion module 4 to adjust the second power supply P2 to be substantially equal to the first power supply P1 based on the demand of the load 200, so as to improve the convenience of use of the uninterruptible power supply system 100. It is worth mentioning that in one embodiment, the controller 5 can be a device such as a microcontroller or a central processing unit, and the uninterruptible power supply system 100 can also include a plurality of voltage / current detectors (not shown) to detect the voltage and current of each point of the uninterruptible power supply system 100 to control the power supply.

[0077] See also Figure 2A The circuit structure diagram of the first embodiment of the uninterruptible power system with voltage adjustment function of the present invention is further combined with Figure 1 .exist Figure 2AIn the embodiment, the controller 5 includes a memory module 52 (for example, but not limited to, a memory device such as a memory). When the controller 5 determines that the first power source P1 is normal through the input signal Si, the memory module 52 of the controller 5 can memorize the voltage value of the first power source P1 (for example, but not limited to 19V), and can also record parameters such as, but not limited to, power factor, current, etc. Then, when the controller 5 determines that the first power source P1 fails through the input signal Si (for example, but not limited to, voltage instability, no voltage, etc.), the controller 5 can control the conversion module 4 to adjust the second power source P2 to be substantially equal to the first power source P1 (for example, but not limited to, 18V to 20V) based on the memorized voltage value (19V), so that the uninterruptible power supply system 100 can actively adjust the second power source P2 to meet the power required for the operation of the load 200 without pre-setting.

[0078] See also Figure 2B The circuit structure diagram of the second embodiment of the uninterruptible power system with voltage adjustment function of the present invention is further combined with Figure 1 to Figure 2A .exist Figure 2B In the embodiment, the controller 5 also includes a memory module 52, and the controller 5 is a controller with a power delivery (Power Delivery; PD) protocol. When the uninterruptible power supply system 100 is coupled to a load 200 that also has a PD protocol, the controller 5 can communicate with the load 200 by handshaking. Therefore, the controller 5 can receive at least one handshaking signal Sh provided by at least one load 200, and the memory module 52 of the controller 5 can memorize the voltage value of the first power source P1 required by the load 200 (for example but not limited to 19V) based on the handshaking signal Sh. Then, when the controller 5 determines that the first power source P1 fails through the input signal Si, the controller 5 can also control the conversion module 4 to adjust the second power source P2 to be substantially equal to the first power source P1 based on the memorized voltage value (19V). It is worth mentioning that in one embodiment, the controller 5 can also have Figure 2A and Figure 2B The function is implemented in a memory manner according to the type of the load 200.

[0079] See also Figure 3A The circuit structure diagram of the third embodiment of the uninterruptible power system with voltage adjustment function of the present invention is further combined with Figure 1 to Figure 2B .At Figure 3AIn the embodiment, the uninterruptible power supply system 100 may further include a switch SW and at least one output detection circuit 6. The switch SW may be connected in series between the input terminal 12 and the node of the conversion module 4 coupled to the bus 1, between the input terminal 12 and the input detection circuit 2, or before the input terminal 12 to receive the first power source P1. The output detection circuit 6 couples the output terminal 14 and the controller 5, and the output detection circuit 6 is used to detect the power source of the output terminal 14 (i.e., the first power source P1 or the second power source P2) to provide at least one output signal So to the controller 5. The controller 5 may determine whether the power source of the output terminal 14 fails (for example, but not limited to, voltage instability, no voltage, etc.) according to the output signal So, and when the controller 5 determines that the power source of the output terminal fails through the output signal So, the controller 5 may know whether the conversion module 4 fails or the first power source P1 fails according to the input signal Si or other detectors.

[0080] When the first power source P1 fails, the controller 5 controls the switch SW to turn off and starts the conversion module 4 to convert the battery power source Pb into the second power source P2. When the conversion module 4 fails or the battery module 3 is damaged, but the first power source P1 is not failed, the controller 5 controls the switch SW to turn on and disable the conversion module 4. When the conversion module 4 fails or the battery module 3 is damaged, and the first power source P1 is not failed, the controller 5 controls the switch SW to turn off and disables the conversion module 4 at the same time. It is worth mentioning that in one embodiment, the switch SW can be a switching element such as a transistor or a relay.

[0081] Further referring to 3A, the uninterruptible power supply system 100 of the present invention can provide an active backup function. The controller 5 can set some battery modules 3 as backup according to user settings, and automatically switch to the backup battery modules 3 when the main power supply battery module 3 is damaged. Specifically, the conversion module 4 further includes a plurality of converters 42, and the converters 42 are coupled to the battery modules 3 and the controller 5. The controller 5 disables at least one converter 42 (hereinafter referred to as the backup converter 42A) of the converters 42 to adjust the battery module 3 coupled to the backup converter 42A to a backup state. When at least another converter of the remaining converters 42 (hereinafter referred to as the main power converter 42B) fails (hereinafter referred to as the failed converter 42C) or at least one battery module 3 of the battery module 3 coupled to the main power converter 42B (hereinafter referred to as the damaged battery module 3A) is damaged, the controller 5 enables the backup converter 42A to provide a backup power supply effect.

[0082] Whether or not a backup effect can be provided depends on the full load current of the load 200. When the second power source P2 is higher than the full load current of the load 200, the uninterruptible power system 100 can provide an active backup function. On the other hand, the uninterruptible power system 100 can provide an active backup function that can be set by the user, set by the controller 5 according to the input signal Si and / or the output signal So, or set by the controller 5 through the handshake signal Sh. It is worth mentioning that in one embodiment, the number of converters 42 can preferably correspond to the number of battery modules 3 to provide a one-to-one conversion function for easy control, and a plurality of switches can be included between the converter 42 and the battery module 3, so that when a converter 42 fails or the battery module 3 is damaged, the switch can be switched to couple to another converter 42 or battery module 3 that is operating normally to maintain the stable power supply capability of the uninterruptible power system 100.

[0083] See also Figure 3B The circuit structure diagram of the third embodiment of the uninterruptible power system with voltage adjustment function of the present invention is further combined with Figures 1 to 3A .At Figure 3B In the present invention, the uninterruptible power supply system 100 can supply power to multiple powered devices (i.e., loads 200) according to a preset power supply sequence, and the controller 5 can distribute power to multiple loads 200 according to user settings, and give priority to supplying power to loads 200 with a higher sequence. Figure 3B In the embodiment, the number of output terminals 14 is multiple, and multiple loads 200 are coupled respectively. The uninterruptible power supply system 100 further includes a power distribution module 7, and the power distribution module 7 is coupled to the output terminal 14, the conversion module 4 and the controller 5. The controller 5 sets the weight ratio Rw of each load 200, and controls the power distribution module 7 to preferentially supply power to the load 200 with a higher weight ratio Rw according to the weight ratio Rw. For example, it is assumed that the load 200 is a server, a fan, a TV and other equipment. The controller 5 can set the weight ratio Rw of the server to be higher, and the weight ratio Rw of the TV to be lower, so that when the uninterruptible power supply system 100 cannot meet the power required by the load 200, the stable operation of the server can still be maintained. It is worth mentioning that in one embodiment, the power distribution module 7 may include multiple switches, current limiting elements and other elements that can adjust the path conduction / disconnection and adjust / limit the current on the path. The detailed circuit structure thereof can be well known to those skilled in the art, and will not be repeated here.

[0084] See also Figure 4A The schematic diagram of the structure and appearance of the uninterruptible power supply system with voltage adjustment function in the first direction of the present invention, Figure 4B The schematic diagram of the structure of the uninterruptible power supply system with voltage adjustment function in the second direction of the present invention is further combined with Figure 1 to Figure 3B , and refer to it repeatedly Figure 4A to Figure 4B. The uninterruptible power supply system 100 includes a body 8, and the body 8 includes a first accommodating space 82, a plurality of slots 84, a control panel 86 and an I / O panel 88. The first accommodating space 82 is formed inside the body 8, and the first accommodating space 82 accommodates the bus 1, the input detection circuit 2, the conversion module 4 and the controller 5. The slots 84 respectively form second accommodating spaces 842 for accommodating the battery modules 3, and the second accommodating space 842 includes a first end 8422 and a second end 8424. The first end 8424 is opened on one side of the body 8 to form a plurality of openings on the outer surface of one side of the body 8. The second end 8424 is configured with a first connecting terminal Cn1, the first connecting terminal Cn1 is coupled to the conversion module 4, and the first connecting terminal Cn1 is used to respectively connect the battery modules 3 so that the battery module 3 is coupled to the conversion module 4.

[0085] Each UPS 100 further includes a plurality of protrusions 844, and the protrusions 844 are used to provide position limiting and foolproof functions when the battery module 3 is inserted into the second accommodation space 842, so that the user will not mistakenly insert the battery module 3 in reverse, causing the conversion module 4 to malfunction, or even causing damage to the UPS 100. It is worth mentioning that in one embodiment, the protrusions 844 can be formed on the outer shell of the body 8, or on the outer shell of the slot 84, and at least one of them can be formed according to the difficulty of the design process of the UPS 100.

[0086] Further reading Figure 4A , Figure 4B , the control panel 86 and the I / O panel 88 are respectively arranged on one side of the main body 8, and the control panel 86 is coupled to the controller 5. The control panel 86 is used to display the parameters of the uninterruptible power supply system 100, which may include, for example but not limited to, parameters such as voltage, current, power, and set values. The I / O panel 88 can be used to receive the first power source P1, and provide a variety of different connector types to couple loads 200 of various connector types. In addition, the I / O panel 88 may also include a signal input / output connector for signal input / output to set / control the uninterruptible power supply system 100. In Figure 4B The slots 84 further include a slide rail 846. The slide rail 846 is formed on one side of the second accommodation space 842 to guide the battery module 3 to dock with the first connection terminal Cn1 of the slot 84 when the battery module 3 is inserted into the second accommodation space 842, so as to make it easier for the battery module 3 to dock with the first connection terminal Cn1.

[0087] See also Figure 5A A schematic diagram of the structure and appearance of a battery module in the first direction of the present invention, Figure 5B This is a schematic diagram of the structure and appearance of the battery module of the present invention in the second direction, and further reference is made to Figure 1 to Figure 4B , and refer to it repeatedly Figure 5A to Figure 5B .exist Figure 5A In the embodiment, the battery module 3 includes a shell 34 and a second connection terminal Cn2. A recess 342 is formed on the outer surface of the shell 34. The recess 342 is used to fit the protrusion 844 to limit the shell 34 of the battery module 3 when the shell 34 is inserted into the second accommodation space 842. The second connection terminal Cn2 is arranged on one side of the shell 34 and corresponds to the position of the first connection terminal Cn1, so as to dock with the first connection terminal Cn1 when the shell 34 slides into the second accommodation space 842. On the other hand, Figure 5B In the embodiment, the housing 34 may further include a slide groove 344. The slide groove 344 is formed on the outer surface of the housing 34 and is used to guide the housing 34 to slide into the second accommodation space 842 by engaging the slide rail 846 after the recess 342 is engaged with the protrusion 844, so as to avoid the possibility that the housing 34 can shake in the second accommodation space 842 after the recess 342 is engaged with the protrusion 844.

[0088] See also Figure 5C A schematic diagram of the appearance of the battery module of the present invention in the first state in the third direction, Figure 5D FIG. 1 is a schematic diagram of the structure appearance of the battery module of the present invention in the second state in the third direction, and further reference is made to FIG. Figures 1 to 5B , and see further Figure 5C to Figure 5D .exist Figure 5C In the embodiment, the battery module 3 may further include a clamping member 36 and a locking member 38. The clamping member 36 is coupled to the housing 34 and is used to clamp the housing 34 in the second accommodation space 842. The locking member 38 is used to lock the clamping member 36 when the housing 34 is clamped in the second accommodation space 842. Specifically, the clamping member 36 includes a clamping portion 362, and the second accommodation space 842 includes a positioning portion (not shown). Figure 5C When the locking state is reached, the locking portion 362 moves to protrude from the housing 34 and is locked with the positioning portion (not shown) so that the housing 34 is locked in the second accommodation space 842. Figure 5D When the engagement is released, the engagement portion 362 moves to retract into the housing 34 to unlock the engagement state so that the housing 34 can move forward and backward in the second accommodation space 842. On the other hand, the locking member 38 can be configured on the engagement member 36, for example but not limited to, Figure 5C When the engaging member 36 is in the engaged state, the locking member 38 can lock the engaging member 36 to prevent the engaging member 36 from being mistakenly released from the engaged state due to vibration or impact.

[0089] See also Figure 6 The internal structure and appearance diagram of the battery module of the present invention is shown in FIG. Figure 1 to Figure 5D .exist Figure 6In the embodiment, the shell 34 is an openable and closable structure, and the shell 34 includes a cover 34A and a body 34B. The cover 34A can be fixed to the body 34B by locking or sliding, so as to form a third accommodation space 346 inside the shell 34. The third accommodation space 346 may include a battery rack, and the battery rack is used to accommodate and clamp a plurality of columnar battery cells 32. Among them, the columnar battery cell 32 can be a 26650 lithium iron phosphate battery cell or a 18650 lithium iron phosphate battery cell, and can also be compatible with 18650 / 26650 lithium ternary battery cells. The present invention is compatible with 18650 & 26650 battery cells through the same mechanism design, so that the end user can choose to use lithium iron phosphate battery cells or lithium ternary battery cells for replacement. Therefore, the convenience of use can be greatly improved.

[0090] On the other hand, the housing may further include a heat sink 34C and / or a heater 34D. The heat sink 34C is disposed in the third accommodation space 346, and is preferably disposed on the cover 34A, so that when the cover 34A is combined with the body 34B, the heat sink 34C can be disposed on one side of the columnar battery core 32. The heat sink 34C is used to dissipate heat from the columnar battery core 32, so that when the temperature of the columnar battery core 32 (for example but not limited to 40 degrees) is higher than the preferred operating temperature of the columnar battery core 32 (for example but not limited to 25 degrees), the temperature of the columnar battery core 32 can be reduced as much as possible. Similarly, the heater 34D can also be disposed in the same position and coupled to the first connection terminal Cn1, so as to generate heat by receiving the third power P3 provided by the lock connected to the first connection terminal Cn1. In this way, the columnar battery cell 32 can be heated and when the temperature of the columnar battery cell 32 (for example but not limited to 10 degrees) is lower than the optimal working temperature of the columnar battery cell 32 (for example but not limited to 25 degrees), the temperature of the columnar battery cell 32 can be increased as much as possible. It is worth mentioning that in one embodiment, the heat sink 34C and the electric heater 34D can be configured on one side and the other side of the columnar battery cell 32 at the same time, so as to adaptively control the temperature of the columnar battery cell 32 in response to the external environment temperature.

[0091] See also Figure 7 This is a flow chart of the operation method of the uninterruptible power supply system with voltage adjustment function of the present invention, and further reference is made to Figure 1 to Figure 6. The operating method of the uninterruptible power supply system 100 is mainly to provide the ability to actively adjust the voltage to improve the ease of use of the uninterruptible power supply system 100. The operating method of the uninterruptible power supply system 100 includes receiving a first power supply through a bus, and an input detection circuit detecting the first power supply to provide an input signal (S100). The uninterruptible power supply system 100 can receive a first power supply P1 through an input terminal 12, and an input detection circuit 2 detects the first power supply P1 to provide an input signal Si according to the first power supply P. Then, the first power supply is judged to be normal according to the input signal, and the first power supply is provided to the load through the bus (S120). A preferred embodiment is to use a controller 5 to judge whether the first power supply P1 is normal through the input signal Si, and when the controller 5 judges that the first power supply P1 is normal through the input signal Si, the first power supply P1 is provided to the output terminal 14 through the bus 1 to power the load 200.

[0092] Then, the first power supply is determined to be failed according to the input signal, and the control conversion module converts the battery power provided by the battery module into the second power supply (S140). When the controller 5 determines that the first power supply P1 fails through the input signal Si, the controller 5 controls the conversion module 4 to convert the battery power Pb into the second power supply P2, so as to provide the second power supply P2 to the output terminal 14 through the bus 1 to power the load 200. Finally, according to the requirements of the load, the control conversion module adjusts the second power supply to be substantially equivalent to the first power supply, so as to provide the second power supply that meets the requirements of the load to the load (S160). Since the uninterruptible power supply system 100 of the present invention has the function of dynamically adjusting the voltage, the controller 5 will control the conversion module 4 to adjust the second power supply P2 to be substantially equivalent to the first power supply P1 based on the requirements of the load 200, so as to provide the second power supply P2 that meets the requirements of the load 200 to the output terminal 14, so as to supply the power required for the operation of the load 200. It is worth mentioning that in one embodiment, Figure 7 For details of steps and processes not described, please refer to Figure 1 to Figure 6 , I will not elaborate on it here.

The present application may also have other embodiments, and those skilled in the art may make various corresponding changes and deformations according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and deformations should fall within the scope of protection of the claims attached to the present application.
