The operation principle of the docking station circuit 10 in this embodiment is specifically as follows:

when the ac power supply 20 is connected, the ac/dc conversion module 100 converts the ac power supplied by the ac power supply 20 into dc power for use, if the uplink device 30 is connected to the docking station circuit 10, the power management controller 2001 detects the charging specification (e.g. 20v,3 a) of the connected uplink device 30, and adjusts the working state (on or off) of each first switch subunit 2003a in the first switch subunit 2003 according to the charging specification, so that the voltage dividing subunit 2003b meeting the voltage dividing capability of the charging specification is connected to the circuit loop, and accordingly performs voltage dividing processing on the dc voltage output by the ac/dc conversion module 100, so as to charge the uplink device 30 by taking the detected charging specification as the target charging specification.

When there is a need for data transmission or data exchange between the uplink device 30 and the downlink device 40, the uplink device 30 and the downlink device 40 connected to the docking station circuit 10 perform data transmission or data exchange through the data exchange module 300; when data transmission or data exchange is needed between the downstream devices 40, the upstream device 30 is used as a medium to realize the data transmission or data exchange between the downstream devices 40, that is, one downstream device 40 firstly transmits data to the upstream device 30 through the data exchange module 300, and then the upstream device 30 transmits the data to the other downstream device 40 through the data exchange module 300, thereby completing the data transmission or data exchange between different downstream devices 40.

The ac power supply 20 further supplies power to the downlink device 40 with a charging or power consumption requirement through the auxiliary power supply unit 2002, specifically, the auxiliary power supply unit 2002 receives a dc electrical signal output from the ac-dc conversion module 100, and outputs an electrical signal (e.g. 5v,3 a) with a stable specification and lower than or equal to an input voltage at an output end thereof through corresponding processing (e.g. voltage reduction, voltage stabilizing adjustment, etc.), so as to charge the downlink device 40 or provide a necessary working power to make the downlink device 40 work normally. It should be noted that, in some embodiments, when the ac power source 20 is not connected, the energy storage device of the upstream device 30 may also be used to charge or provide the working power for the downstream device 40 through the auxiliary power unit 2002, so as to adapt the docking station circuit 10 to more working scenarios.

Referring to fig. 16, fig. 16 shows a circuit structure of an ac/dc conversion module 100, and the following circuit structure in combination with the embodiment shown in fig. 15 is used to explain the working principle of the ac/dc conversion module 100, which is specifically as follows:

in this embodiment, the rectifying unit 1001 includes a rectifying bridge D1 and a first capacitor C1 (filter capacitor), the isolation transforming unit includes a fourth switching tube Q4 and a fifth switching tube Q5, the first inductor L1 (resonant inductor), the second capacitor C2 (resonant capacitor), the transformer T1, the second diode D2 (rectifier diode), the third diode D3 (rectifier diode) and the third capacitor C3 (filter capacitor), and the control unit 1003 is a Microcontroller (MCU) U15.

The alternating current provided by the alternating current power supply 20 is rectified by a rectifier bridge D1 and filtered by a first capacitor C1, then enters an LLC resonant converter formed by a first inductor L1, a second capacitor C2 and a transformer T1 for isolation conversion, and is rectified by a full-wave rectifier circuit formed by a second diode D2 and a third diode D3 and filtered by a third capacitor C3 to obtain proper direct current voltage output. The microcontroller U15 adjusts the resonant frequency of the LLC resonant converter by controlling the switching frequencies of the fourth switching tube Q4 and the fifth switching tube Q5, so that the fourth switching tube Q4 and the fifth switching tube Q5 operate in a soft switching state, thereby improving the conversion efficiency.

It should be noted that, the rectifying unit 1001 may be other types of rectifying functional modules, such as a half-wave rectifying circuit, the isolation transforming unit 1002 may be other types of isolation transforming functional modules, such as a forward transforming circuit, a flyback transforming circuit, etc., and the rectifying portion of the isolation transforming unit 1002 may be any rectifying type functional module, such as a half-wave rectifying, a synchronous rectifying, etc., which is not limited herein.

In some embodiments, referring to fig. 15 again, the ac/dc conversion module 100 further includes a power factor correction unit 1004. The first end of the power factor correction unit 1004 is connected to the second end of the rectifying unit 1001, the second end of the power factor correction unit 1004 is connected to the first end of the isolation conversion unit 1002, the control end of the power factor correction unit 1004 is connected to the second output end of the control unit 1003, and the power factor correction unit 1004 is used for improving the output power factor of the ac/dc conversion module 100.

Referring to fig. 16 again, the power factor correction unit 1004 in the present embodiment is a conventional BOOST circuit, which includes a sixth switching tube Q6, a second inductor L2, a fourth diode D4 and a fourth capacitor C4.

Referring to fig. 16 again, the voltage feedback unit 1005 in this embodiment operates as follows:

when the output voltage of the ac/dc conversion module 100 is greater than the preset threshold, the voltage stabilizing tube D5 is turned on, and the current flowing through the optocoupler U16 increases, so that the output current of the output end FB increases, and then the control unit 1003 changes the switching frequencies of the fourth switching tube Q4 and the fifth switching tube Q5 in the isolation conversion unit 1002, so that the output of the isolation conversion unit 1002 correspondingly decreases, thereby ensuring that the output of the isolation conversion unit 1002 maintains dynamic balance, and that is, realizing the effect of voltage stabilizing output. In some embodiments, in order to make the control logic of the voltage variation of the isolation transformation unit 1002 simpler, a voltage regulating circuit based on an adjustable voltage regulator may be additionally arranged at the output end of the isolation transformation unit, and the output variation of the voltage regulating circuit is controlled to realize the simple control of the output voltage variation of the ac/dc conversion module 100.

In other embodiments, the multiple voltage dividing subunits 2003b may be added to the circuit loop according to a preset condition combination to obtain a target voltage dividing result (for example, the second voltage dividing resistor RS2 and the third voltage dividing resistor RS3 are both connected to the circuit loop to participate in voltage division), so as to meet the charging requirements of multiple different specifications.
