[0002] With the development of electronic devices, the number of electronic devices used by users in daily life has increased significantly. Ordinary single-port chargers can no longer meet the needs of users, so multi-port chargers have emerged. Most of the current multi-port chargers are equipped with a DC voltage regulation module for each output port to output power, thereby realizing power supply for multiple external electronic devices through multiple output ports.

[0030] The control method of the multi-output port charger provided by the embodiment of the present invention closes the control switch when one output terminal of the multi-output port charger is connected to an external device, so that the first voltage regulation module and the second voltage regulation module are connected in parallel to output power to the output terminal together, and then the output terminal can provide the maximum output power of the multi-output port charger to the external device; and the two voltage regulation modules are connected in parallel to reduce the overall internal resistance of the voltage regulation module, thereby reducing the energy consumption based on the internal resistance, thereby avoiding the problem of excessive heating of the part of the circuit where only a single voltage regulation module is located, reducing the overall heating of the circuit, and improving the charging efficiency of the circuit.

[0039] The second output switch is controlled to be closed, so that the first voltage regulating module outputs the second power to the first output end to power the first external device, and the second voltage regulating module outputs the third power to the second output end to power the second external device.

[0040] In one embodiment, see Figure 3 , after step S12, for example, further comprising the steps of:

[0041] S13: Detecting that the third output terminal is connected to a third external device;

[0042] S14: Control the control switch to be disconnected, so that the first voltage regulating module outputs the fourth power to the first output end to power the first external device, and the first voltage regulating module outputs the fifth power to the third output end to power the third external device.

[0043] In another embodiment, see Figure 4 , after step S16, for example, further comprising the steps of:

[0044] S17: Detecting that the third output terminal is connected to a third external device;

[0045] S18: Control the control switch to be disconnected, so that the first voltage regulating module outputs the sixth power to the first output terminal to power the first external device, the first voltage regulating module outputs the seventh power to the third output terminal to power the third external device, and the second voltage regulating module outputs the eighth power to the second output terminal to power the second external device.

[0046] See also Figure 5 This embodiment further provides a multi-output port charger 10 , and the control method of the multi-output port charger can be applied to the multi-output port charger 10 , for example.

[0047] To facilitate understanding of the present invention, the following Figure 1-Figure 6 The multi-output port charger 10 and each step of the control method of the multi-output port charger of this embodiment are described in detail.

[0048] Specifically, the multi-output port charger 10 includes, for example, a controller 100, a conversion module 200, a control switch 300, a first voltage regulating module 410, a first output terminal 430, a second voltage regulating module 510, and a second output terminal 530. The control switch 300, the first voltage regulating module 410, the first output terminal 430, the second voltage regulating module 510, and the second output terminal 530 are electrically connected to the controller 100, respectively, the first voltage regulating module 410 and the second voltage regulating module 510 are also electrically connected to the control switch 300 and the conversion module 200, respectively, the first output terminal 430 is electrically connected to the first voltage regulating module 410, for example, for connecting to a first external device; the second output terminal 530 is electrically connected to the second voltage regulating module 510, for example, for connecting to a second external device. The controller 100 mentioned above is, for example, an MCU (Microcontroller Unit), the conversion module 200 is, for example, an AC-DC conversion circuit, and the first voltage regulation module 410 and the second voltage regulation module 510 are, for example, both DC-DC regulation circuits. The control switch 300 is, for example, a MOSFET tube (Metal Oxide Semiconductor Field Effect Transistor), which can be opened and closed under the control of the controller 100. When the control switch 300 is closed, the first voltage regulation module 410 is connected in parallel with the second voltage regulation module 510.

[0049] It should be noted that the conversion module 200, for example, converts the AC voltage into a DC voltage and distributes it to the first voltage regulating module 410 and the second voltage regulating module 510. For example, the maximum output power of the multi-output port charger 10 is, for example, 100W, and the first voltage regulating module 410 and the second voltage regulating module 510 can be allocated 50W of power respectively according to the preset power distribution rule. For the multi-output port charger in the prior art, when only one port is connected to an external device, for example, only one DC voltage regulating module works, that is, the maximum output power of the port is only 50W, which cannot reach the maximum output power of the multi-output port charger. For the multi-output port charger 10 in the embodiment of the present application, when only one port is connected to an external device, the control switch 300 is closed, the first voltage regulating module 410 and the second voltage regulating module 510 are connected in parallel, and both work as the output port output power, so that the maximum output power of the port can reach the maximum output power of the multi-output port charger 10, which is 100W.

[0050] Further, see Figure 5 The multi-output port charger 10 further includes, for example, a first output switch 420 and a second output switch 520. The first output switch 420 and the second output switch 520 are electrically connected to the controller 100, respectively. The first output switch 420 is electrically connected between the first voltage regulating module 410 and the first output terminal 430, and the second output switch 520 is electrically connected between the second voltage regulating module 510 and the second output terminal 530. For example, the first output switch 420 and the second output switch 520 are also MOSFET tubes, which can be opened and closed under the control of the controller 100.

[0051] When the controller 100 detects that the first output terminal 430 is connected to the first external device (corresponding to Figure 1 The controller 100 controls the control switch 300 to close, so that the first voltage regulating module 410 and the second voltage regulating module 510 are connected in parallel to output the first power to the first output terminal 430 to supply power to the first external device (corresponding to Figure 1Step S12). Specifically, the controller 100 controls the control switch 300 to be closed, so that the first voltage regulating module and the second voltage regulating module are connected in parallel; the controller 100 also controls the first output switch 420 to be closed, so that the first voltage regulating module 410 and the second voltage regulating module 510 jointly output the first power to the first output terminal 430 to power the first external device. At this time, the first voltage regulating module 410 and the second voltage regulating module 510 are both working and output the first power to the first output terminal 430 together, so that the first power can, for example, reach the maximum output power of 100W of the multi-output port charger 10, which improves the charging efficiency of the multi-output port charger 10 when a single external device is connected, and the two voltage regulating modules are connected in parallel to reduce the overall internal resistance of the voltage regulating module, thereby reducing the energy consumption based on the internal resistance, thereby avoiding the problem of excessive heating of the part of the circuit where only a single voltage regulating module is working, reducing the overall heating of the circuit, and improving the charging efficiency of the circuit. In addition, the service life of a single voltage regulating module can be improved.

[0052] Based on the above, when the controller 100 also detects that the second output terminal 530 is connected to the second external device (corresponding to Figure 2 The controller 100 controls the control switch 300 to be disconnected, so that the first voltage regulating module 410 outputs the second power to the first output terminal 430 to power the first external device, and the second voltage regulating module 510 outputs the third power to the second output terminal 530 to power the second external device (corresponding to Figure 2 Step S16 in the figure). Specifically, the controller 100, for example, controls the control switch 300 to be disconnected, and then controls the second output switch to be closed 520, so that the first voltage regulating module 410 outputs the second power to the first output terminal 430 to power the first external device, and the second voltage regulating module 510 outputs the third power to the second output terminal 530 to power the second external device. At this time, the first voltage regulating module 410 outputs the second power to the first output terminal 430, and the second voltage regulating module 510 outputs the third power to the second output terminal 530. The first voltage regulating module 410 and the second voltage regulating module can charge the two external devices respectively according to the preset power allocation rule. The second power is, for example, the same as the third power. For example, the second power and the third power are, for example, half of the maximum output power of 100W of the multi-output port charger 10, that is, 50W power. By first disconnecting the control switch and then closing the second output switch, it is possible to avoid damage to the newly connected second external device caused by excessive power.

[0053] See also Figure 6 The multi-output port charger 10 further includes, for example: a third output terminal 440, the third output terminal 440 is, for example, electrically connected to the controller 100 and the first output switch 420, the third output terminal 440 is, for example, connected in parallel with the first output terminal 430, and the third output terminal 440 is, for example, used to connect a third external device.

[0054] In a specific embodiment, after the controller 100 detects that the first output terminal 430 is connected to the first external device, it detects that the third output terminal 440 is connected to the third external device (corresponding to Figure 3 The controller 100 controls the control switch 300 to be disconnected, so that the first voltage regulating module 410 outputs the fourth power to the first output terminal 430 to power the first external device, and the first voltage regulating module 410 also outputs the fifth power to the third output terminal 440 to power the third external device (corresponding to Figure 3 Step S14). At this time, the control switch 300 is disconnected, the first output switch 420 is closed, and the first voltage regulating module 410 works to output the fourth power to the first output terminal 430, and also outputs the fifth power to the third output terminal 440. For example, the fourth power and the fifth power are both preset safety powers. For example, if the first voltage regulating module 410 is allocated with 50W power, the fourth power and the fifth power are 25W power, respectively. In this way, damage to low-power external devices connected to the first output terminal 430 and the third output terminal 440 can be avoided.

[0055] In another specific embodiment, after the controller 100 detects that the first output terminal 430 is connected to the first external device and the second output terminal 530 is connected to the second external device, it detects that the third output terminal 440 is connected to the third external device (corresponding to Figure 4 The controller 100 controls the control switch 300 to be disconnected, so that the first voltage regulating module 410 outputs the sixth power to the first output terminal 430 to power the first external device, the first voltage regulating module 410 outputs the seventh power to the third output terminal 440 to power the third external device, and the second voltage regulating module 510 outputs the eighth power to the second output terminal 530 to power the second external device (corresponding to Figure 4Step S18). At this time, the control switch 300 is disconnected, the first output switch 420 and the second output switch 520 are both closed, the first voltage regulating module 410 works to output the sixth power to the first output terminal 430, and also outputs the seventh power to the third output terminal 440, and the second voltage regulating module 510 outputs the eighth power to the second output terminal 530. The sixth power and the seventh power are, for example, safe power, and the eighth power is, for example, a higher output power. For example, if the first voltage regulating module 410 and the second voltage regulating module 510 are both allocated 50W power, then at this time, the sixth power and the seventh power are, for example, 25W power respectively, and the eighth power is, for example, 50W power, that is, the first output terminal 430 and the third output terminal 440 are, for example, connected to external devices with lower power, and the second output terminal 530 can be, for example, connected to external devices with higher power. In this way, not only can damage to the low-power external devices connected to the first output terminal 430 and the third output terminal 440 be avoided, but also the external devices connected to the second output terminal 530 can be powered with higher efficiency.

[0056] It should be noted that the first power, second power, third power, fourth power, fifth power, sixth power, seventh power, and eighth power mentioned above are all examples, and this application does not limit the specific power. In actual production and use, power allocation can be performed according to actual conditions. In addition, when the second output terminal is connected to the second external device alone, or the third output terminal is connected to the third external device alone, the specific situation is the same as the situation where the first output terminal is connected to the first external device alone, and this application does not elaborate on this.

[0057] In summary, the control method of the multi-output port charger provided by the embodiment of the present invention closes the control switch when one output terminal of the multi-output port charger is connected to an external device, so that the first voltage regulation module and the second voltage regulation module are connected in parallel to output power to the output terminal together, and then the output terminal can provide the maximum output power of the multi-output port charger for the external device; and the two voltage regulation modules are connected in parallel to reduce the overall internal resistance of the voltage regulation module, thereby reducing the energy consumption based on the internal resistance, thereby avoiding the problem of excessive heating of the part of the circuit where only a single voltage regulation module is working, reducing the overall heating of the circuit, and improving the charging efficiency of the circuit.
