Alternating current is periodic in nature, i.e., the positive and negative of the electrodes alternate. Another type is an air conditioner powered by direct current, which is generally powered by a battery device, such as an air conditioner installed in an automobile, because the battery device does not have periodicity, in other words, the positive and negative poles of the battery do not change periodically. At this time, it can be stated that such a dc type air conditioner does not face the problem of the periodic variation of the positive and negative poles of the power supply when receiving electric power.
Therefore, when using an air conditioner powered by dc power, the air conditioner may suffer from a circuit burn-out problem if the power source is in reverse connection.

In order to avoid this problem, the user or engineer needs to know that the current power supply is in the reverse connection state in time, so that the air conditioner can be powered off in time, and the condition that the air conditioner is damaged is avoided.

In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for the purpose of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes are not set forth in detail in order to avoid obscuring the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
As shown in fig. 1, fig. 1 is an embodiment of a protection circuit provided by the present application, where the protection circuit is used for protection of a target circuit, and the protection circuit includes a protection module 101, a control module 201, and a display module 301;
the target circuit is electrically connected with a power supply through the protection module 101, and the control module 201 is electrically connected with the protection module 101 and the display module 301 respectively; the protection module 101 is configured to protect the target circuit 401 when the power supply is reversely connected, and transmit a reverse connection signal of the power supply to the control module 201; the control module 201 is configured to control the display module 301 to display the reverse connection state of the power supply according to the reverse connection signal.
In this embodiment, the protection module 101 is respectively connected to the power supply and the target circuit 401, and when the power supply is turned on, the current flows into the target circuit 401 through the protection module 101. If the power supply direction of the power supply is normal, that is, the connection mode between the power supply and the protection module 101 is in a positive connection state, the current provided by the power supply can smoothly flow into the target circuit 401 through the protection module 101, so that the protection circuit 401 can normally operate. The target circuit 401 may be any circuit structure that operates in any circuit, for example: an inverter circuit in the dc current air conditioner, etc., and the details thereof are not limited herein.
If the connection mode between the power supply and the protection module 101 is abnormal, for example, if the connection is lost manually, the positive electrode and the negative electrode of the power supply may be connected to the protection module 101 in the reverse direction, the interface that needs to be connected to the positive electrode of the power supply in the protection module 101 is connected to the negative electrode, the interface that needs to be connected to the negative electrode of the power supply in the protection module 101 is connected to the positive electrode, and the flow direction of the current is reversed. It is known that when the current flows in a direction other than the normal direction, the circuit is easily damaged. At this time, when the positive electrode and the negative electrode of the power supply are reversely connected, the protection module 101 may prevent the current from being conducted, prevent the reverse current from providing electric energy for the target circuit 401, and prevent the target circuit 401 from being damaged.
In other words, the protection module 101 triggers the protection mechanism when the current direction changes to the reverse direction. At this point, the control module 201 may detect that the protection module 101 has triggered a protection mechanism, such as: when the power supply starts working, the control module 201 does not detect the phenomenon of the conduction current of the protection module 101, and at this time, the control module 201 may regard that the protection module 101 has triggered the protection mechanism, that is, the current power supply has a reverse connection phenomenon. At this time, the control module 201 may control the display module 301 to display the text message with the semantic of "the current power supply is in the reverse connection state" to prompt the corresponding user that the current power supply is in the reverse connection state.
It should be noted that, according to the present embodiment, it can be seen that the power supply does not currently supply power to the control module 201, and in order to enable the control module 201 to work in time, it is detected whether the protection module 101 triggers the protection mechanism. Similarly, the power supply does not currently supply power to the display module 301. Therefore, an additional external power supply can be separately arranged for supplying power to the control module 201 and the display module 301. For example: an external power supply is directly electrically connected with the control module 201 and the display module 301, and the external power supply and a power supply in the circuit adopt a power supply control system started by the circuit. That is, when the power control system receives a control signal of the starting circuit, the corresponding switch is directly controlled to be closed, and the two power supplies are controlled to start to supply power at the same time. The external power source and the power source control system are arranged in various ways, and may be arranged according to specific situations, and are not limited herein, and the external power source and the power source control system do not belong to the content of the present application, and are not shown in fig. 1.
This application is through being connected protection module and target circuit, be connected control module and protection module and display module, so, on the module that has protect function, carry out the electricity through corresponding control module and display module and connect, when the protection mechanism was triggered to the protection module that corresponds, control module can in time acquire the information that protection module triggered the protection mechanism, and will generate the tie-back information that is used for telling the user and show on display module, make the user can in time know that current circuit is in the tie-back state, the risk of circuit damage has been reduced.
As shown in fig. 2, fig. 2 is an embodiment of a protection circuit provided in the present application, where the protection circuit further includes:
a rectifying module 501, wherein the rectifying module 501 is electrically connected with the control module 201 and the power supply respectively;
the rectifying module 501 is configured to rectify a voltage signal of the power supply and transmit the rectified voltage signal to the control module 201.
According to the above embodiments, the protection circuit of the present application may supply power to the control module 201 and the display module 301 through an external power source. In particular cases, the power supply is a device with a certain risk factor due to the phenomenon of spontaneous combustion that may occur in the power supply itself. In addition, in order to save cost or make the overall structure of the circuit more simplified, and at the same time make the safety factor of the circuit higher, the original power supply may be directly used to supply power to the control module 201 and the display module 301 without providing an additional power control system and an external power supply.
According to the application scenario of the present application, the power supply is a dc power supply, which has a risk of reverse connection, and if the reverse connection occurs, the target circuit 401 may be damaged. In other words, if the power supply module directly supplies power to the control module 201 and the display module 301, there is also a risk that the control module 201 and the display module 301 are damaged due to the reverse connection of the power supply. Therefore, in order to avoid this situation, if the control module 201 and the display module 301 need to be directly powered by the power supply, a rectifier module needs to be added to rectify the reverse current, adjust the direction of the current, protect the control module 201 and the display module 301, and avoid the control module 201 and the display module 301 from being damaged when the power supply is reversely connected.
The rectifier module may be a rectifier bridge. The connection mode of rectifying by using the rectifier bridge may refer to the prior art, and the detailed description of the connection mode is omitted here.
By adding the rectifying device, the power supply can directly supply power to the control module and the display module, so that an additional external power supply and an additional power supply control system are saved, and the effect of saving the circuit cost is achieved.
As shown in fig. 3, fig. 3 is an embodiment of a protection circuit provided in the present application, where the protection circuit further includes:
and the adjusting power module 601, where the adjusting power module 601 is electrically connected to the rectifying module 501 and the control module 201, respectively. The regulated power supply module 601 is used to regulate the voltage of the current.
In a normal situation, when the power supply is used, assuming that the power supply provides a dc power for a battery device, the power supply capability decreases with the use of the battery device, that is, the power supply voltage gradually decreases with the passage of time, and after the voltage decreases, the rated voltage of the control module 201 may not be reached, so that the control module 201 and/or the display module 301 may not work normally. Alternatively, when a battery device with a weak power supply capability is used, the power supply voltage of the battery device may not reach the rated voltage of the control module 201, and the control module 201 and/or the display module 301 may not work normally. Therefore, in order to avoid the situation that the control module 201 and/or the display module 301 cannot work normally, the adjusting power module 601 may be added to adjust the voltage to the normal working voltage of the control module 201 and/or the display module 301. For example, the regulation regulates the voltage to 24 volts. The adjusting power module 601 may be combined by a transformer, a switching power chip and an optical coupling isolation feedback device.
As shown in fig. 4, fig. 4 is an embodiment of a protection circuit provided by the present application, where the protection module 101 includes a protection submodule 102 and a switching device 103 connected in series, and the protection submodule 102 is electrically connected to a positive electrode of a power supply; the protection submodule 102 is used for protection of the target circuit 401; the switching device 103 is used for control of current conduction in the circuit.
In this embodiment, the protection sub-module 102 is the same as the protection function of the protection target circuit 401 of the protection module 101 in the above embodiments, and specifically relates to the description of the protection function, which is not described herein again. Compared with the protection 101, the protection submodule 102 has an additional voltage level adjusting function. Specifically, if the power supply is connected in the normal connection mode as shown in fig. 4, a current flows from the positive electrode of the power supply, a part of the current flows through the protection sub-module 102, a part of the current flows into the target circuit 401, and the current flowing into the target circuit 401 flows back to the switching device 103, and the switching device 103 prevents the current from flowing back to the negative electrode of the power supply. At this time, the circuit cannot form a closed loop, and thus the target circuit 401 cannot operate. Since the current connection state is a normal state, the current passing through the protection sub-module 102 may pass through the protection sub-module 102. Therefore, the protection sub-module 102 needs to pressurize the current passing through the protection sub-module 102, so that the pressurized current can turn on the switching device 103, and the current flowing back from the target circuit 401 can pass through the switching device 103, so that the whole circuit forms a closed loop, and thus the target circuit 401 can work normally.
On the contrary, if the power supply is reversely connected, in this case, a current actually flows from the negative electrode (positive electrode in reverse connection), the current does not pass through the protection sub-module 102 but directly passes through the switching device, and the current that is not boosted at this time cannot open the switching device, so that the circuit cannot form a closed loop, thereby protecting the target circuit 401. The switch device includes a first switch interface, a second switch interface, and a third switch interface, where the first switch interface is electrically connected to the protection sub-module 102, the second switch interface is electrically connected to the negative electrode of the power supply, and the third switch interface is electrically connected to the target circuit 401. The first switch interface, the second switch interface and the third switch interface of the switch device 103 are not numbered in fig. 4, and the switch device 103 may be a MOS transistor.
As shown in fig. 5, for an embodiment of a protection circuit provided by the present application, the protection sub-module 102 includes a protection device 1021 and a voltage regulation module 1022, which are connected in series, where the protection device 1021 is used for conducting current in one direction, and the voltage regulation module 1022 is used for regulating voltage after current conduction.
According to the above embodiment, when the power supply is in the reverse connection state and the voltage of the current is not increased, the switching device 103 cannot be turned on, and when the current flowing from the positive electrode of the power supply passes through the switching device 103, the circuit is in the open state, and the positive electrode, the target circuit 401 and the negative electrode cannot form a closed loop. However, according to the characteristics of the switching device 103, although the positive electrode of the power supply cannot form a closed loop with the negative electrode through the target circuit 401, the current flowing from the positive electrode of the power supply flows back to the negative electrode of the power supply when passing through the switching device 103 and then passing through the protection submodule 102, and the power supply is in another closed loop.
It is known that when a circuit forms a closed loop, if there is no working device, the circuit may be short-circuited, thereby causing the circuit to burn out, and the phenomenon of burning out is avoided. At this time, it is necessary that the current reaches the protection submodule 102 after passing through the switching device 103, and an open circuit is formed to prevent the current from flowing back to the negative electrode. Therefore, a protection device 1021 is needed, and the protection device 1021 may be a device for conducting current in one direction, so that the current can only conduct in one direction. Thus, after the current passes through the voltage adjusting module 1022, even if the voltage of the current is increased, the current does not flow back to the negative electrode of the power supply due to the unidirectional current conduction characteristic of the protection device 1021, and a closed loop is prevented from being formed, so that a short circuit occurs in the circuit. The protection device 1021 comprises a first protection interface and a second protection interface, and the positive electrode of the power supply is electrically connected with the first protection interface; the voltage regulating module 1022 includes a first regulating interface electrically connected to the second protection interface and a second regulating interface electrically connected to the first switch interface of the switching device. The first protection interface and the second protection interface of the protection device 1021, and the first regulation interface and the second regulation interface of the voltage regulation module 1022 are not numbered in the figure. Meanwhile, the protection device 1021 may be a diode, and the voltage regulation module 1022 may be a DC-DC module.
As shown in fig. 6, fig. 6 is an embodiment of a protection circuit provided in the present application, and the control module 201 is electrically connected to the second protection interface and the first adjustment interface through a preset reverse connection information obtaining interface. Or, the control module 201 is electrically connected to the second adjusting interface and the first switch interface of the switch device through a preset reverse connection information obtaining interface.
When the power supply is in the reverse connection state, the circuit is in the open circuit state. According to the actual current flowing condition, when the circuit is in the open circuit state, the positive electrode and the negative electrode of the power supply are not connected and conducted, and therefore the potential difference cannot be formed, so that the actual condition is that no current exists in the circuit, and when the control module 201 is connected with the protection submodule 102, the control module 201 obtains the information that: no current flows in the circuit. Therefore, no matter whether the reverse connection information acquisition interface of the control module 201 is electrically connected with any device in the protection module 101, the control module 201 cannot detect the current in the circuit. Therefore, when there is no current in the circuit, the control module 201 can determine the reverse connection phenomenon of the circuit. Fig. 5 shows a connection manner in which the control module 201 is electrically connected to the second protection interface and the first adjustment interface through a preset reverse connection information obtaining interface. Fig. 6 shows a connection manner in which the control module 201 is electrically connected to the second adjustment interface and the first switch interface through a preset reverse connection information obtaining interface. The difference between the two connection modes in this embodiment is that, because the actual circuit structure is subject to the problem of wiring in a specific device, different connection modes can be selected according to specific situations.
This application is through being connected protection module and target circuit, be connected control module and protection module and display module, so, on the module that has protect function, carry out the electricity through corresponding control module and display module and connect, when the protection mechanism was triggered to the protection module that corresponds, control module can in time acquire the information that protection module triggered the protection mechanism, and will generate the tie-back information that is used for telling the user and show on display module, make the user can in time know that current circuit is in the tie-back state, the risk of circuit damage has been reduced.

For example: the protection circuit in fig. 7 may be the protection circuit in fig. 1, and the protection circuit includes a protection module 101, a control module 201, and a display module 301;
