The preset noise signal value may be a value set according to a specific application scenario and a specific application requirement, for example, the same value may be set for different power supply devices. For example, the respective corresponding values may be set for different power supply apparatuses.

According to the embodiment, under the condition that the charging equipment generates abnormal sound, the power quantity of the electric equipment is combined to determine how to adjust the output power of the power supply equipment so as to avoid noise power under the condition that the electric equipment is normally charged.
In one embodiment, the power conversion apparatus 10 includes a plurality of input communication detection modules, for example, as shown in fig. 3, where the power conversion apparatus 10 includes an input communication detection module 1012 in addition to the input communication detection module 1011, where the input communication detection module 1011 is a wireless communication detection module described above and is used for connecting to the power supply apparatus 201 (wireless charger), and the input communication detection module 1012 is a wired communication detection module described above and is used for connecting to the power supply apparatus 202 (wired charger), and of course, other input detection modules may be included, and this embodiment is defined herein.

As shown in fig. 3, the noise signal may be noise generated by the power supply apparatus 201 and the power supply apparatus 202 connected in parallel.
The set constraint may be to keep the total output power of the power supply apparatus 201 and the power supply apparatus 202 unchanged. In particular, the method can be realized on the premise of keeping the total output power unchanged,
as shown in fig. 3, when the first detection module 103 detects that the noise signal values of the noise signals generated by the power supply device 201 and the power supply device 202 exceed the preset noise signal value, the processing unit 104 may control the power conversion module 105, for example, to adjust the output power duty ratios of the power supply device 201 and the power supply device 202 respectively until the abnormal noise disappears. For example, the output power of the power supply device 201 may be adjusted to a small value, and the output power of the power supply device 202 may be adjusted to a small value, or vice versa, the output power of the power supply device 201 may be adjusted to a small value, and the output power of the power supply device 202 may be adjusted to a small value, and the power may be adjusted to a suitable ratio until the abnormal sound disappears by continuously adjusting the output power of the power supply device 202 to a small value.
In this embodiment, when the plurality of power supply devices are input in parallel, the abnormal sound is generated by charging, and when the total output power is kept unchanged, the abnormal sound problem is solved by adjusting the respective output power ratio of the plurality of power supply devices, so that quieter rapid charging is realized.

In this embodiment, the output ends of the plurality of output communication detection modules are respectively connected to the first input ends of the second detection module 106, and the input ends of the plurality of output communication detection modules are respectively connected to the output ends of the voltage distribution module 107 in a one-to-one correspondence manner.
Illustratively, as shown in fig. 3, the output terminal of the output communication detection module 1021 and the output terminal of the output communication detection module 1022 are respectively connected to the first input terminal of the second detection module 106. The input end of the output communication detection module 2011 and the input end of the output communication detection module 2012 are respectively connected to the output end of the voltage distribution module 107.

The processing unit 104 controls the power conversion module 105 to keep the total output power of the power supply device 201 and the power supply device 202 unchanged by adjusting the output power of the power supply device 201 to a little higher and adjusting the output power of the power supply device 202 to a little lower until the abnormal noise is eliminated.
For example, as shown in fig. 3, when the first detection module 103 detects that the noise signal values of the noise signals generated by the power supply device 201 and the power supply device 202 exceed the preset noise signal value, and when the second detection module 106 detects that the total residual electric power values of the electric equipment 301 and the electric equipment 302 are greater than the preset electric power value, the first detection module 103 sends a fourth correction signal for reducing the output power of the power supply device 201 to the control unit 104. The processing unit 104 controls the power conversion module 105 to keep the total output power of the power supply device 201 and the power supply device 202 unchanged by adjusting the output power of the power supply device 201 to a small value and adjusting the output power of the power supply device 202 to a small value until the abnormal sound is eliminated.

In this embodiment, when the processing unit 104 detects that the power supply device 201 is abnormal (any power has abnormal noise), the power supply device 201 is turned off, and the energy storage module 108 is also started immediately, so that on one hand, the energy storage module 108 can supply power to other modules inside the power conversion device 10. On the other hand, the electric energy of the energy storage module 108 is converted into a voltage v1 required by the power supply device 301 and a voltage v2 required by the power supply device 302 through the intelligent voltage distribution of the voltage distribution module 107, and then is transmitted to the corresponding electric equipment 301 and the electric equipment 302 through the corresponding output communication detection module 1021 and the corresponding output communication detection module 1022, so that the corresponding electric equipment can be charged quickly. Of course, the energy storage module 108 may not be started, and the power supply device 202 may directly reset the power ratio to rapidly charge the electric device 301 and the electric device 302.
In this embodiment, the power conversion device 10 adds an energy storage module, i.e. a standby power group, so that the power conversion device 10 can be charged even after the device is powered down, and the electric device can be charged continuously and rapidly.

The data storage module 110 decodes the first charging protocol and stores the decoded information of the first charging protocol. For example, the data storage module 110 decodes the first charging protocols sent by the power supply device 201 and the power supply device 202, and stores the information of the charging protocol of the power supply device 201 obtained after decoding.

In this embodiment, the UI control interface of the electric device 301 sends a control instruction to the processing unit 104 of the power conversion device 10, and if the control instruction belongs to an immediate turn-off charging control instruction, the processing unit 104 immediately sends a turn-off instruction to the output communication detection module 1021 to turn off the power supply of the power conversion device 10 to the electric device 301.
If the control command is a timing T1 (for example, 1 hour) and then turns off the charging control command, the processing unit 104 starts its own timer function after receiving the command, and immediately sends a turn-off command to the output communication detection module 1021 to turn off the power supply of the power conversion device 10 to the electric device 301 after the countdown T1 arrives.
If the control command is a charging control command after the timing T2 (for example, 1 hour), the processing unit 104 starts its own timer function after receiving the command, and immediately sends the charging control command to the output communication detection module 1021 to connect the power conversion device 10 to supply power to the electric device 301 after the countdown T2 arrives.
In this embodiment, after the UI interaction interface of the electric device receives the bluetooth signal and matches the bluetooth signal successfully, the power conversion device 10 and the electric device establish a signal transmission path, and the UI interaction interface can read data recorded in the data storage module 111, such as input/output voltage, input/output current, working temperature, noise, charging time, protection condition, abnormal condition, and the like.
Meanwhile, the designer can modify the parameters of the power supply equipment and the power conversion equipment 10 through the Bluetooth encryption function, so that the designer can update the parameters, optimize the design, facilitate operation, avoid disassembling and debugging, and save time.
In one embodiment, as shown in fig. 3, the power conversion apparatus 10 further includes a second communication module 111, and the second communication module 111 is connected between the second detection module 106 and the first communication module 109. The second communication module 111 is further connected to the processing unit 104, and the second communication module 111 is further connected to the second detection module 106.
In fig. 3, the second communication module 111 communicates bi-directionally with the processing unit 104.
In this embodiment, the first communication module 109 receives the second charging protocol of the electric device, and sends the second charging protocol to the second communication module 111. For example, the first communication module 109 receives the first charging protocols sent by the electric devices 301 and 302, and sends the first charging protocols to the second communication module 111.
The second communication module 111 decodes the second charging protocol and stores information of the second charging protocol obtained after the decoding. For example, the second communication module 111 decodes the second charging protocols sent by the electric device 301 and the electric device 302, and stores the decoded information of the second charging protocols.
