The power input unit 4 is connected to an external power source to receive an input power, and the power input unit 4 is electrically connected to the power socket module 3 through the power input port 11. The power factor correction control circuit unit 5 is located in the housing 1 and is electrically connected to the power socket module 3. The LLC resonant converter control circuit unit 6 is located in the housing 1 and is electrically connected to the power factor correction control circuit unit 5. The power delivery unit 7 includes a Buck module 71, and the power delivery unit 7 is located in the housing 1. The power delivery unit 7 is used to step up or step down the input power to the universal serial bus socket 2. According to some embodiments, the LLC resonant converter control circuit unit 6 can be a phase-shift full-bridge circuit or a single-phase half-bridge circuit, and the present application is not limited thereto.
[0043] In this embodiment, the housing 1 is provided with four universal serial bus sockets 2 and two power sockets 3. However, the present application is not limited thereto. According to some embodiments, the high power hub has more than four universal serial bus sockets 2 and four power sockets 3. This is determined according to the needs of the producer or user.
[0044] In some embodiments, the power delivery unit 7 can support USB PD 3.0. However, the present application is not limited thereto, and according to some embodiments, the power delivery unit 7 can support USB PD 3.1.
[0045] According to Figure 1 In the illustrated embodiment, the power delivery unit 7 further comprises a hub control circuit module 72, which can be one or more, and when the universal serial bus sockets 2 are multiple, the hub control circuit module 72 is also multiple, and each is electrically connected to a corresponding universal serial bus socket 2. In this way, when multiple electronic devices are plugged into these universal serial bus sockets 2, data transmission can be performed. The electronic devices can be, for example, smart mobile devices (mobile phones, tablet computers, or notebook computers) or hard drives.
[0046] In some embodiments, the power delivered by the power delivery unit 7 is 5-48V. For example, it can be 5V, 9V, 12V, 15V, 20V, 28V, 36V, or 48V. According to some embodiments, the power delivery unit 7 can support USB PD 3.0. However, the present application is not limited thereto, and according to some other embodiments, the power delivery unit 7 can also be designed to support USB PD 3.1. For example, each universal serial bus socket 2 is Type-C, and when a single universal serial bus socket 2 is plugged in (electrically connected to an electronic device), the power delivery unit 7 can provide the function of USB PD 3.1.
[0047] According to some embodiments, when multiple electronic devices are electrically connected to the universal serial bus sockets 2 (i.e., each universal serial bus socket 2 is in use), the power delivery unit 7 can provide energy with a total power of 300-600W to these electronic devices.

[0050] Referring to Figure 3 Fig. 6 is a schematic diagram of the architecture of a high-power hub Z2 according to another embodiment of the present application. According to this embodiment, the PFC control circuit unit is a totem pole PFC control circuit unit 5', which uses only four metal-oxide-semiconductor field-effect transistors (MOSFETs) instead of multiple diodes, thereby greatly reducing losses and improving the performance of the high-power hub and facilitating the development of the product toward a small size.
[0051] Referring to Figure 4 Fig. 7 is a top view of the housing 1 of a high-power hub Z3 according to an embodiment of the present application. The USB receptacles 2 are multiple, and are divided into first USB receptacles 21 and second USB receptacles 22, the plug-in interfaces of the first USB receptacles 21 being different from the plug-in interfaces of the second USB receptacles 22. In Figure 4 In the embodiment shown, the plug-in interfaces of the first USB receptacles 21 are Type-C, and there are four of them. The plug-in interfaces of the second USB receptacles 22 are Type-A, and there is one of them. However, this is only an embodiment, and in some embodiments, the high-power hub can also have three plug-in interfaces of Type-C and three plug-in interfaces of Type-A, and the present application is not limited thereto.
