[0022] The first circuit 102 is connected to the third circuit 105 of the first power adapter 104 and is used to output a first voltage signal;

[0023] In which, the first end of the third circuit 105 can be connected to a power supply (also known as a power supply device), and the second end of the third circuit 105 can be connected to the first end of the first circuit 102; the third circuit 105 of the power adapter 104 is used to convert the AC input of the power supply device into a DC output, and the second end of the first circuit 102 can be connected to the power consumption component 101.

[0024] A second circuit 103 is connected to a fourth circuit 107 of a second power adapter 106 and is configured to output a second voltage signal. The first power adapter 104 and the second power adapter 106 may be the same or different.

[0025] In which, the first end of the fourth circuit 107 can be connected to the power supply, and the second end of the fourth circuit 107 can be connected to the first end of the second circuit 103; the fourth circuit 107 of the second power adapter 106 is used to convert the AC input of the power supply device into a DC output, and the second end of the second circuit 103 can be connected to the power consumption component 101.

[0026] The first circuit and the second circuit may be connected in parallel, and the first voltage signal and the second voltage signal may simultaneously supply power to at least one of the power consumption components 101 .

[0027] In an embodiment of the present application, by setting a first circuit and a second circuit corresponding to the two circuits of the power adapter in the electronic device, the first voltage signal output by the first circuit and the second voltage signal output by the second circuit can simultaneously power the power consumption component, thereby improving the charging efficiency; when the power consumption of the power consumption component is large, there is no need to additionally design a dedicated charging port, thereby reducing the charging cost.

[0028] Figure 2a This is a schematic diagram of the structure of another electronic device according to an embodiment of the present application. Figure 2a As shown, the electronic device 200 includes:

[0066] At least one power consumption component 401, configured to consume power;

[0067] The first circuit 402 is connected to the third circuit 405 of the first power adapter 404 and is used to output a first voltage signal;

[0068] In which, the first circuit 402 includes a first interface circuit 4021 and a first controller 4022 of the first interface circuit 4021; the third circuit 405 includes a third interface circuit 4051 and a third controller 4052 of the third interface circuit 4051; the first end of the first interface circuit 4021 is connected to the first end of the third interface circuit 4051, the second end of the first interface circuit 4021 is connected to the first end of the first controller 4022, the third end of the first interface circuit 4021 is connected to the power consumption component 401, and the second end of the first controller 4022 is connected to the power consumption component 401; the second end of the third interface circuit 4051 is connected to the second end of the third controller 4052, the third end of the third interface circuit 4051 is connected to the power supply, and the first end of the third controller 4052 is connected to the power supply.

[0069] The first controller 4022 is configured to communicate with the third controller 4052 through the first interface circuit 4021 and the third interface circuit 4051 to obtain at least a first voltage parameter output by the first interface circuit 4021;

[0070] The first voltage parameter is used to determine a parameter value of the first voltage signal; when the first voltage parameter is 20V, the parameter value of the first voltage signal may be 20V.

[0071] A second circuit 403 is connected to a fourth circuit 407 of a second power adapter 406 and is configured to output a second voltage signal. The first power adapter 404 and the second power adapter 406 may be the same or different.

[0072] In which, the second circuit 403 includes a second interface circuit 4031 and a second controller 4032 of the second interface circuit 4031; the fourth circuit 407 includes a fourth interface circuit 4071 and a fourth controller 4072 of the fourth interface circuit 4071; the first end of the second interface circuit 4031 is connected to the first end of the fourth interface circuit 4071, the second end of the second interface circuit 4031 is connected to the first end of the second controller 4032, the third end of the second interface circuit 4031 is connected to the power consumption component 401, and the second end of the second controller 4032 is connected to the power consumption component 401; the second end of the fourth interface circuit 4071 is connected to the second end of the fourth controller 4072, the third end of the fourth interface circuit 4071 is connected to the power supply, and the first end of the fourth controller 4072 is connected to the power supply.

[0073] The second controller 4032 is configured to communicate with the fourth controller 4072 via the second interface circuit 4031 and the fourth interface circuit 4071 to obtain at least the second voltage parameter output by the second interface circuit 4031. Similarly, the second voltage parameter is used to determine a parameter value of the second voltage signal.

[0074] The first voltage signal and the second voltage signal can simultaneously supply power to at least one of the power consumption components 401 .

[0075] In an embodiment of the present application, communication between the first controller and the third controller can determine the parameter value of the first voltage signal, and communication between the second controller and the fourth controller can determine the parameter value of the second voltage signal, thereby better determining the charging voltages of the first circuit and the second circuit.

[0076] In some embodiments, as Figure 4b As shown, the first controller 4022 is connected to the second controller 4032;

[0077] The third terminal of the first controller 4022 may be connected to the third terminal of the second controller 4032 .

[0078] The first controller 4022 is configured to determine the power consumption of at least one of the power consuming components 401, and control whether the first voltage signal supplies power to the at least one of the power consuming components 401 according to the power consumption; and send the power consumption to the second controller 4032;

[0079] Among them, the first controller 4022 can be a master controller and the second controller 4032 can be a slave controller. The power consumption of the power consumption component can be determined by the first controller 4022 as the master controller, and the power consumption can be sent to the second controller 4032 as the slave controller.

[0080] The second controller 4032 is used to control whether the second voltage signal supplies power to at least one of the power consumption components 401 according to the consumed power.

[0081] In some embodiments, as Figure 4b As shown, the first controller 4022 is used to control the first voltage signal to power or not power at least one of the power consumption components 401 when the power consumption is less than the first threshold; and control the first voltage signal to power at least one of the power consumption components 401 when the power consumption is not less than the first threshold;

[0082] The second controller 4032 is used to control the second voltage signal to not supply power or supply power to at least one of the power consumption components 401 when the power consumption is less than the first threshold; and to control the second voltage signal to supply power to at least one of the power consumption components 401 when the power consumption is not less than the first threshold.

[0083] Among them, the first threshold value can be 80W, 100W, 120W, etc. When the power consumption is not less than the first threshold value, due to the large power consumption, two charging circuits are required to simultaneously power the power consumption components. Therefore, the first voltage signal and the second voltage signal can be controlled to simultaneously power at least one of the power consumption components 401; when the power consumption is less than the first threshold value, due to the small power consumption, one charging circuit can meet the charging demand. Therefore, the first voltage signal can be controlled to power at least one of the power consumption components 401, and the second voltage signal can not power at least one of the power consumption components 401; or, the first voltage signal can be controlled to not power at least one of the power consumption components 401, and the second voltage signal can power at least one of the power consumption components 401.

[0084] In the embodiment of the present application, the first voltage signal and the second voltage signal can be determined to charge the power consuming component selectively or together according to the power consumption of the power consuming component. When the power consumption is small, the first voltage signal or the second voltage signal can be selected to charge the power consuming component. When the power consumption is large, the first voltage signal and the second voltage signal can be used to charge the power consuming component simultaneously, thereby improving the charging flexibility and charging efficiency.

[0085] Figure 5a This is a schematic diagram of the structure of another electronic device according to an embodiment of the present application. Figure 5a As shown, the electronic device 500 includes:

[0086] At least one power consumption component 501, configured to consume power;

[0087] The first circuit 502 is connected to the third circuit 505 of the first power adapter 504 and is used to output a first voltage signal;

[0088] In which, the first circuit 502 includes a first interface circuit 5021, a first controller 5022 of the first interface circuit 5021, and a first switch circuit 5023; the third circuit 505 includes a third interface circuit 5051 and a third controller 5052 of the third interface circuit 5051, the first end of the first interface circuit 5021 is connected to the first end of the third interface circuit 5051, the second end of the first interface circuit 5021 is connected to the first end of the first controller 5022, and the third end of the first interface circuit 5021 is connected to the first end of the first switch circuit 5023; the second end of the first controller 5022 is connected to the second end of the first switch circuit 5023; the third end of the first switch circuit 5023 is connected to the power consumption component 501; the second end of the third interface circuit 5051 is connected to the second end of the third controller 5052, the third end of the third interface circuit 5051 is connected to the power supply, and the first end of the third controller 5052 is connected to the power supply.

[0089] The first controller 5022 is used to communicate with the third controller 5052 through the first interface circuit 5021 and the third interface circuit 5051 to obtain at least the first voltage parameter output by the first interface circuit 5021; the first voltage parameter is used to determine the parameter value of the first voltage signal.

[0090] A second circuit 503 is connected to a fourth circuit 507 of a second power adapter 506 and is configured to output a second voltage signal. The first power adapter 504 and the second power adapter 506 may be the same or different.

[0091] In which, the second circuit 503 includes a second interface circuit 5031 and a second controller 5032 of the second interface circuit 5031 and a second switch circuit 5033; the fourth circuit 507 includes a fourth interface circuit 5071 and a fourth controller 5072 of the fourth interface circuit 5071; the first end of the second interface circuit 5031 is connected to the first end of the fourth interface circuit 5071, the second end of the second interface circuit 5031 is connected to the first end of the second controller 5032, and the third end of the second interface circuit 5031 is connected to the first end of the second switch circuit 5033; the second end of the second controller 5032 is connected to the second end of the second switch circuit 5033; the third end of the second switch circuit 5033 is connected to the power consumption component 501; the second end of the fourth interface circuit 5071 is connected to the second end of the fourth controller 5072; the second end of the fourth interface circuit 5071 is connected to the power supply, and the first end of the fourth controller 5072 is connected to the power supply; the third end of the first controller 5022 is connected to the third end of the second controller 5032.

[0092] The second controller 5032 is used to communicate with the fourth controller 5072 through the second interface circuit 5031 and the fourth interface circuit 5071 to obtain at least the second voltage parameter output by the second interface circuit 5031; the second voltage parameter is used to determine the parameter value of the second voltage signal.

[0093] Wherein, the first voltage signal and the second voltage signal can simultaneously power at least one of the power consumption components 501;

[0094] The first controller 5022 is configured to determine the power consumption of at least one of the power consuming components 501, and adjust the closed state of the first switch circuit 5023 according to the power consumption to control whether the first voltage signal supplies power to the at least one of the power consuming components 501; and send the power consumption to the second controller 5032;

[0095] The second controller 5032 is configured to adjust the closed state of the second switch circuit 5033 according to the consumed power, so as to control whether the second voltage signal supplies power to at least one of the power consumption components 501 .

[0096] Among them, when the power consumption of the power consumption component 501 is not less than 100W, the electronic device can be considered to be in heavy load mode. When the power consumption of the power consumption component 501 is less than 100W, the electronic device can be considered to be in light load mode. The charging strategy of the electronic device can be adjusted to improve the charging efficiency of the power consumption component 501 by adjusting the closed state of the first switch circuit 5023 and the second switch circuit 5033.

[0097] In the light load mode, the second controller 5032 can control the closing state of the second switch circuit 5033 to be open, and the first controller 5022 can control the closing state of the first switch circuit 5023 to be closed, that is, the first voltage signal supplies power to at least one of the power consumption components 501, and the second voltage signal does not supply power to at least one of the power consumption components 501; or the second controller 5032 can control the closing state of the second switch circuit 5033 to be closed, and the first controller 5022 can control the closing state of the first switch circuit 5023 to be open, that is, the second voltage signal supplies power to at least one of the power consumption components 501, and the first voltage signal does not supply power to at least one of the power consumption components 501.

[0098] In the overload mode, the second controller 5032 can control the closing state of the second switch circuit 5033 to be closed, and the first controller 5022 can control the closing state of the first switch circuit 5023 to be closed, that is, the first voltage signal and the second voltage signal jointly power at least one of the power consumption components 501.

[0099] In an embodiment of the present application, the first voltage signal and the second voltage signal can be selected to charge the power consuming component or both of them by switching the closed state of the switch circuit according to the power consumption of the power consuming component. When the power consumption is small, the first voltage signal or the second voltage signal can be selected to charge the power consuming component. When the power consumption is large, the first voltage signal and the second voltage signal can be used to charge the power consuming component at the same time, thereby improving the charging flexibility and charging efficiency. By switching the closed state of the switch circuit, the power supply circuit can be selected more conveniently.

[0100] In some embodiments, as Figure 5b As shown, the electronic device also includes a fifth circuit 508, the third end of the first switch circuit 5023 is connected to the first end of the fifth circuit 508, the third end of the second switch circuit 5033 is connected to the second end of the fifth circuit 508, and the third end of the fifth circuit 508 is connected to the power consumption component 501.

[0101] The first controller 5022 is configured to obtain a first current parameter output by the first interface circuit 5021 and feed the first current parameter back to the third interface circuit 5051 so that the third controller 5052 adjusts the first current parameter to obtain a third current parameter.

[0102] The second controller 5032 is configured to obtain a second current parameter output by the second interface circuit 5031 and feed the second current parameter back to the fourth interface circuit 5071 so that the fourth controller 5072 adjusts the second current parameter to obtain a fourth current parameter.

[0103] The difference between the third current parameter and the fourth current parameter is smaller than the difference between the first current parameter and the second current parameter.

[0104] like Figure 5b As shown, the first circuit 502 and the second circuit 503 are connected in parallel, the first voltage parameter of the first circuit 502 and the second voltage parameter of the second circuit 503 are equal, and the first current parameter of the first circuit 502 and the second current parameter of the second circuit 503 may be unbalanced. When the power consumption component 501 requires a charging power of 150W, due to the imbalance between the first current parameter and the second current parameter, the first output power of the first circuit 502 may be 30W and the second output power of the second circuit 503 may be 100W, resulting in over-power protection.

[0105] Therefore, it is necessary for the first controller 5022 to detect the first current parameter in real time and feed it back to the third controller 5052, and the third controller 5052 adjusts the first current parameter to the third current parameter; the second controller 5032 needs to detect the second current parameter in real time and feed it back to the fourth controller 5072, and the fourth controller 5072 adjusts the second current parameter to the fourth current parameter, so as to achieve current balance between the third current parameter and the fourth current parameter.

[0106] In some embodiments, the difference between the third current parameter and the fourth current parameter may be 0, that is, the third current parameter and the fourth current parameter are equal.

[0107] In some embodiments, the first interface circuit 5021, the second interface circuit 5031, the third interface circuit 5051 and the fourth interface circuit 5071 can all be USB (Universal Serial Bus) Type-C interfaces; the first power adapter 504 and the second power adapter 506 can be the same power adapter, and the first power adapter 504 has a dual-channel Type-C interface output, one channel is the third interface circuit 5051, and the other channel is the fourth interface circuit 5071; the third interface circuit 5051 and the fourth interface circuit 5071 can both support a maximum output power of 100 watts (unit: W), a maximum output voltage of 20 V, and a maximum output current of 5 amps (unit: A).

[0108] The first controller 5022, the second controller 5032, the third controller 5052 and the fourth controller 5072 can all be PD (Photo Diode) controllers, also known as PD IC (Integrated Circuit Chip). The first controller 5022 and the third controller 5052 can communicate the charging protocol between the first power adapter 504 and the first circuit 502 of the electronic device; the second controller 5032 and the fourth controller 5072 can communicate the charging protocol between the second power adapter 506 and the second circuit 503 of the electronic device.

[0109] Among them, the Type-C interface of each interface circuit can include a CC1 pin and a CC2 pin, and the CC1 pin and CC2 pin can be responsible for the communication of the USB PD (Power Delivery) protocol, such as the communication of the first voltage parameter between the CC1 pin and CC2 pin of the first interface circuit 5021 and the CC1 pin and CC2 pin of the third interface circuit 5051; the communication of the second voltage parameter between the CC1 pin and CC2 pin of the second interface circuit 5031 and the CC1 pin and CC2 pin of the fourth interface circuit 5071.

[0110] In addition, the CC1 and CC2 pins can also detect device access; detect the device insertion direction and use it to establish data channel routing; establish the device role, discover and configure the USB PD power supply mode; discover and configure optional backup and auxiliary modes, etc.

[0111] In addition, the Type-C interface of each interface circuit can also include a D+ pin, a D- pin, a Vbus pin and a GND pin. When the electronic device is a laptop computer, each controller can reuse the D+ pin and D- pin of the corresponding interface circuit to provide I2C (Inter-Integrated Circuit, two-wire serial bus) communication for dual-path current sharing (i.e., two-path current balancing) and closed-loop control for charging; the Vbus pin and GND pin of each interface circuit can provide a charging circuit.

[0112] In an embodiment of the present application, the two Type-C input ports (the first interface circuit and the second interface circuit) of the electronic device are charged simultaneously by the dual Type-C output ports (the third interface circuit and the fourth interface circuit) of the power adapter, so that the first voltage signal output by the first circuit and the second voltage signal output by the second circuit simultaneously power the power consumption component, thereby improving the charging efficiency; when the power consumption of the power consumption component is large, there is no need to design an additional dedicated charging port, thereby reducing the charging cost; by detecting the current parameters of the first circuit and the second circuit and adjusting them to make the current of the first circuit and the second circuit balanced, overcurrent protection can be avoided.

[0113] In some embodiments, the second controller 5032 is further configured to send the second current parameter to the first controller 5022;

[0114] The first controller 5022 is further configured to feed back the second current parameter to the third interface circuit 5051, so that the third controller 5051 adjusts the first current parameter according to the first current parameter and the second current parameter to obtain a third current parameter, and sends the third current parameter to the first controller 5022;

[0115] The third current parameter may be any value between the first current parameter and the second current parameter, or may be an average value of the first current parameter and the second current parameter.

[0116] The first controller 5022 is further configured to send the third current parameter to the second controller 5032;

[0117] The second controller 5032 is further configured to send the third current parameter to the fourth interface circuit 5071 , so that the fourth controller 5072 adjusts the second current parameter according to the third circuit parameter to obtain a fourth current parameter.

[0118] The difference between the third current parameter and the fourth current parameter may be smaller than a preset threshold, and the fourth current parameter may be equal to the third current parameter.

[0119] In the embodiment of the present application, by determining the third current parameter and the fourth circuit parameter based on the first current parameter and the second current parameter, current balancing can be achieved more accurately.

[0120] In some embodiments, as Figure 5c As shown, the third controller 5052 is connected to the fourth controller 5072;

[0121] The fourth controller 5072 is configured to send the second current parameter to the third controller 5052;

[0122] The third controller 5052 is configured to adjust the first current parameter according to the first current parameter and the second current parameter to obtain a third current parameter, and send the third current parameter to the fourth controller 5072;

[0123] The fourth controller 5072 is configured to adjust the second current parameter according to the third current parameter to obtain a fourth current parameter.

[0124] In the embodiment of the present application, by connecting the third controller and the fourth controller, the third current parameter and the fourth circuit parameter can be determined more conveniently based on the first current parameter and the second current parameter, thereby achieving current balancing more accurately.

[0125] Figure 6 This is a schematic diagram of the structure of another electronic device according to an embodiment of the present application. Figure 6 As shown, on the left is a dual-port Type-C output adapter (Power Adapter) 601 and its internal design 602, and on the right is a laptop computer 603 (Notebook) with dual Type-C ports and its internal power supply 604. The adapter has two Type-C outputs, each supporting a maximum of 100W (20V5A). During the charging process, the two output ports simultaneously charge the laptop's two input ports. Inside the laptop, the two outputs are connected in parallel to form one, which is then stepped down by a buck converter (step-down converter) to power the laptop's internal system.

[0126] Due to USB-PD protocol specifications, standard Type-C chargers can only charge at a maximum power of 100W (20V5A). Therefore, for some laptops with power consumption exceeding 100W, non-Type-C charging solutions are required. Since Type-C is standard on mainstream laptops, these laptops require a dedicated charging port in addition to the Type-C port, adding extra design redundancy and cost.

[0127] Each Type-C port corresponds to a PD controller, which is responsible for communicating the charging protocol between devices. In addition, based on this dual-channel parallel charging solution, the PD controller also has a pin multiplexing function, which is responsible for current sharing and closed-loop control of the dual-channel charging.

[0128] The pinout for the Type-C interface is as follows: Vbus and GND provide the charging circuit; CC1 and CC2 handle USB-PD protocol communication; D+ / D- typically support mobile device charging but are not used for laptop charging. Therefore, the PD IC can reuse these two pins to provide I2C communication for closed-loop control of the charging system.

[0129] Because the laptop connects two outputs in parallel, the voltages remain consistent, but the output currents are uncontrollable. This is because the laptop and the adapter lack a closed-loop control loop. In an open-loop state, the two outputs are unbalanced. For example, when the system requires 150W charging power, due to the imbalance, one output may only output 30W, while the other may exceed 100W, triggering overpower protection.

[0130] In this case, the two PD ICs inside the notebook monitor the output currents of each channel in real time and feed the current values back to the adapter. The adapter then makes appropriate adjustments based on the feedback values to ensure that the two output currents are balanced, forming a closed loop for system control.

[0131] In both light and heavy load modes, the laptop PD IC can adjust the charging strategy to improve efficiency by adjusting the switch. For example, in light load mode (system power consumption less than 100W), opening Switch 2 and closing Switch 1, or opening Switch 1 and closing Switch 2, will result in only one path providing power, while the other path will be inoperative. In heavy load mode (system power consumption greater than or equal to 100W), both Switch 1 and Switch 2 are closed, charging both paths simultaneously, and the aforementioned current-sharing control strategy is employed.
