The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0056] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0057] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0059] The embodiments of the present application provide a multi-standard circuit, an uninterruptible power supply, and a control method and device for a multi-standard circuit, which can perform multiple voltage conversions on the input voltage to achieve compatibility with multiple voltage standards.

[0060] First, the multi-standard circuit provided in the embodiment of the present application is described. Figure 1 , Figure 1 It is an optional structural diagram of a multi-standard circuit provided in an embodiment of the present application. The multi-standard circuit includes an input terminal 101, an output terminal 102, a switching control module 103 and a transformer module 104; the input terminal 101 is used to receive an input voltage; the output terminal 102 is used to output a voltage; the switching control module 103 is used to control the input terminal 101 to be connected to the output terminal 102; or, it is used to control the input terminal 101 to be connected to the first terminal of the transformer module 104, and to control the second terminal of the transformer module 104 to be connected to the output terminal 102, so that the transformer module 104 performs a first transformation on the input voltage; or, it is used to control the input terminal 101 to be connected to the second terminal of the transformer module 104, and to control the first terminal of the transformer module 104 to be connected to the input terminal 101, so that the transformer module 104 performs a second transformation on the input voltage; wherein the first transformation is different from the second transformation.

[0061] Here, the input terminal 101 is used to receive an input voltage. The output terminal 102 is used to output a voltage. In the embodiment of the present application, the multi-standard circuit can be connected to the input terminal or the output terminal of an uninterruptible power supply (UPS). If the multi-standard circuit is connected to the input terminal of the UPS, the input voltage of the multi-standard circuit can be the mains, and the output terminal 102 is connected to the UPS. If the multi-standard circuit is connected to the output terminal of the UPS, the input voltage of the multi-standard circuit can be the voltage output by the UPS, the input terminal 101 of the multi-standard circuit is connected to the UPS, and the output terminal of the multi-standard circuit can be connected to the power load.

[0062] In actual implementation, the switching control module 103 of the multi-standard circuit can control the input end 101 to be directly connected with the output end 102, so that the voltage standard of the multi-standard circuit is the first voltage standard. The switching control module 103 can also control the input end 101 to be connected with the first end of the transformer module 104, and control the second end of the transformer module 104 to be connected with the output end 102, so that the transformer module 104 performs a first transformation on the input voltage, so that the voltage standard of the multi-standard circuit is the second voltage standard. The switching control module 103 can also control the input end 101 to be connected with the second end of the transformer module 104, and control the first end of the transformer module 104 to be connected with the input end 101, so that the transformer module 104 performs a second transformation on the input voltage, so that the voltage standard of the multi-standard circuit is the third voltage standard. Among them, the first transformation is different from the second transformation. Here, the first transformation can be a step-up, and the second transformation can be a step-down. In one embodiment, the first voltage transformation may be a step-down, and the second voltage transformation may be a step-up. In some embodiments, in the first voltage system, the output voltage is consistent with the input voltage; illustratively, the input voltage may be 110V AC, and the output voltage output by the output terminal 102 is also 110V AC; or, the input voltage is 220V AC, and the output voltage output by the output terminal 102 is also 220V AC. In the second voltage system, the input voltage is lower than the output voltage; illustratively, the input voltage may be 110V AC, and the output voltage output by the output terminal 102 is 220V AC. In the third voltage system, the input voltage is higher than the output voltage; illustratively, the input voltage may be 220V AC, and the output voltage output by the output terminal 102 is 110V AC. The frequencies of the input voltage and the output voltage are consistent, for example, they may both be 50Hz or 60Hz.

[0063] In the embodiment of the present application, when the input voltage passes from the first end of the transformer module 104 to the second end of the transformer module 104, the transformer module 104 performs a first transformation on the input voltage, and when the input voltage passes from the second end of the transformer module 104 to the first end of the transformer module 104, the transformer module 104 performs a second transformation on the input voltage. In some embodiments, the transformer module is a transformer, and the number of turns of the two windings of the transformer is different. Exemplarily, if the first transformation is step-down, the number of turns of the winding corresponding to the first end of the transformer is less than the number of turns of the winding corresponding to the second end, for example, the number of turns of the winding corresponding to the first end: the number of turns of the winding corresponding to the second end is 1:2, then when the input voltage passes from the first end of the transformer to the second end, the input voltage is stepped down to 1 / 2 of the original, and when the output voltage passes from the second end of the transformer to the first end, the input voltage is stepped up to 2 times the original. If the first transformation is step-up, the number of turns of the winding corresponding to the first end of the transformer is greater than the number of turns of the winding corresponding to the second end. In some embodiments, the transformer module 104 may be a step-up transformer, a step-down transformer, or an AC-AC transformer circuit.

[0064] In the embodiment of the present application, the control module controls the connection between the input end, the transformer module and the input end so that the input voltage can directly pass to the output end, pass to the output end after the first transformation through the transformer module, or pass to the output end after the second transformation through the transformer module. The input voltage can be converted into multiple voltages to achieve compatibility with multiple voltage standards.

[0065] In some embodiments, see Figure 2 , Figure 2 It is an optional structural diagram of the multi-standard circuit provided in the embodiment of the present application. The switching control module 103 includes a control module 201, a first switching module 202 and a second switching module 203; the control module 201 is also used to control the first switching module 202 and the second switching module 203 so that the input end 101 is connected to the output end 102; or, it is also used to control the first switching module 202 and the second switching module 203 so that the input end 101 is connected to the first end of the transformer module 104 and the second end of the transformer module 104 is connected to the output end 102; or, it is also used to control the first switching module 202 and the second switching module 203 so that the input end 101 is connected to the second end of the transformer module 104 and the first end of the transformer module 104 is connected to the input end 101.

[0066] In actual implementation, the control module 201 may be, for example, a microcontroller. The control module 201 is connected to the first switching module 202 and the second switching module 203, and can control the conduction connection mode of the first switching module 202 and the second switching module 203 respectively. The first switching module 202 is connected to the input end 101, the transformer module 104 and / or the output end 102 of the multi-standard circuit. The second switching module 203 is connected to the input end 101, the transformer module 104 and / or the output end 102 of the multi-standard circuit. The embodiment of the present application does not specifically limit the specific connection mode of the first switching module 202 and the second switching module 203 in the circuit. The control module 201 can control the conduction connection between the input end 101 and the output end 102 by controlling the conduction connection of the first switching module 202 and the second switching module 203.

The first end 2031 of the second switching module 203 is the input end of the second switching module 203, and the second end 2032, the third end 2033 and the fourth end 2034 of the second switching module 203 are the output ends of the second switching module 203. At the same time, the input end of the switching module can be connected to only one output end, while the other output ends are disconnected from the input end. In the embodiment of the present application, the control module 101 can control the conduction and disconnection of each end in the first switching module 202 and the second switching module 203 to perform switching control of each voltage system. Here, the first switching module 202 or the second switching module 203 can be a four-contact switch, for example, a relay. In some embodiments, the first switching module 202 or the second switching module 203 can also be a switch module composed of multiple switches. The embodiment of the present application does not specifically limit the structures of the first switching module 202 and the second switching module 203 .

[0069] In some embodiments, see Figure 3B , Figure 3A 2 is an optional structural diagram of a multi-standard circuit provided in an embodiment of the present application.

In a specific implementation scenario, for the above two controls, a control method can be pre-selected for the control module 201 to execute.

[0070] In some embodiments, see Figure 4A , Figure 4AIt is an optional structural diagram of a multi-standard circuit provided in an embodiment of the present application. The first switching module 202 includes a first switch 401, a second switch 402 and a third switch 403, the first contact of the first switch 401 is the first end 2021 of the first switching module 202, the second contact of the first switch 401 is the second end 2022 of the first switching module 202, the third contact of the first switch 401 is connected to the first contact of the second switch 402 and the first contact of the third switch 403, the second contact of the second switch 402 is the third end 2023 of the first switching module 202, and the second contact of the third switch 403 is the fourth end 2024 of the first switching module 202.

When the control module 201 simultaneously controls the first contact of the first switch 401 to be conductive with its third contact, the first contact of the second switch 402 to be conductive with its second contact, and the first contact of the third switch 403 to be disconnected with its second contact, the input end 101 is conductively connected with the first end 1041 of the transformer module 104; at this time, the control module 201 also controls the first end 2031 of the second switching module 203 to be conductively connected with its third end 2033, so that the output end 102 is conductively connected with the second end 1042 of the transformer module 104.

When the voltage standard of the multi-standard circuit needs to be controlled to the first voltage standard, the control module 201 may control the first end 2021 of the first switching module 202 to be connected to the third end 2023 thereof, control the two contacts of the fourth switch 501 to be closed, the two contacts of the fifth switch 502 to be disconnected, and the two contacts of the sixth switch 503 to be closed; or control the first end 2021 of the first switching module 202 to be connected to the fourth end 2043 thereof, control the two contacts of the fourth switch 501 to be closed, the two contacts of the fifth switch 502 to be closed, and the two contacts of the sixth switch 503 to be disconnected.

The second switching module includes a fourth switch RLY4, a fifth switch RLY5 and a sixth switch RLY6. The connection method of each switch on the same voltage line is the same as Figures 4 and 5, and will not be repeated here. In one embodiment, interlocking logic may be provided between the second switch RLY2 and the sixth switch RLY6, and between the third switch RLY3 and the fifth switch RLY5 to prevent the second switch RLY2 and the sixth switch RLY6 from being closed at the same time, and to prevent the third switch RLY3 and the fifth switch RLY5 from being closed at the same time.

When the voltage standard of the multi-standard circuit needs to be controlled to the first voltage standard, when the voltage standard of the multi-standard circuit needs to be controlled to the first voltage standard, the control module 201 may control the two contacts of the first switch RLY1 to be closed, the two contacts of the second switch RLY2 to be closed, the two contacts of the third switch RLY3 to be disconnected, the two contacts of the fourth switch RLY4 to be closed, the two contacts of the fifth switch RLY5 to be disconnected, and the two contacts of the sixth switch RLY6 to be closed; or, control the two contacts of the first switch RLY1 to be closed, the two contacts of the second switch RLY2 to be disconnected, the two contacts of the third switch RLY3 to be closed, the two contacts of the fourth switch RLY4 to be closed, the two contacts of the fifth switch RLY5 to be closed, and the two contacts of the sixth switch RLY6 to be disconnected.

The control module 201 can assist in controlling the first switching module 202 and the second switching module 203 according to the sampled voltage. For example, if the sampled voltage is 220V, then the input voltage is avoided from being boosted, and if the sampled voltage is 110V, then the input voltage is avoided from being stepped down, etc.
