The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
The first embodiment,
Referring to fig. 1, the present application discloses a multi-port adapter with a novel topology, where the multi-port adapter 1 mainly includes a power-taking port 11, a control circuit 14, a plurality of conversion circuits (e.g., conversion circuits 121, 122, 123) and a plurality of power-supplying ports (e.g., power- supplying ports 131, 132, 133), which are described below.
The electricity taking port 11 is used for being connected with a commercial power network D0 and obtaining alternating current commercial power from the commercial power network D0. For example, the power-taking port 11 may be a common two-phase plug, and when the plug is plugged into a socket, AC220V/50Hz alternating current commercial power can be obtained.
The plurality of power supply ports are used for being respectively connected with the electric equipment and outputting direct current to the electric equipment connected with each power supply port. For example, the power supply port 131 may be connected to the electric device D1, the power supply port 132 may be connected to the electric device D2, and the power supply port 133 may be connected to the electric device D3, so that when any one of the electric devices is connected, the connected electric device is supplied with dc power. It can be understood that after the electric equipment obtains the direct current electric energy from the power supply port correspondingly connected to the electric equipment, the electric equipment can meet the circuit working requirement of the electric equipment itself, and can meet the charging requirement of the electric equipment itself, and no specific limitation is made here.
Each of the plurality of conversion circuits (for example, the conversion circuits indicated by reference numerals 121, 122, and 123, respectively) includes an input terminal, an output terminal, and a control terminal, the input terminal of each conversion circuit is connected to the power supply port 11, and the output terminal of each conversion circuit is connected to each power supply port in a one-to-one correspondence manner. For example, the input terminals of the conversion circuits 121, 122, and 123 are connected to the power supply port 11, the output terminal of the conversion circuit 121 is connected to the power supply port 131, the output terminal of the conversion circuit 122 is connected to the power supply port 132, and the output terminal of the conversion circuit 123 is connected to the power supply port 133. In addition, each of the conversion circuits is configured to receive a control signal through a control terminal thereof, and convert AC mains power received by an input terminal thereof into DC power under the action of the control signal and output the DC power through an output terminal thereof, for example, the conversion circuit 121 may convert AC mains power of AC220V into DC power of DC 5V.
In this embodiment, the number of the plurality of conversion circuits should be the same as the number of the plurality of power supply ports, and if there are three power supply ports, three conversion circuits are required, so that one conversion circuit is arranged between the power supply port 11 and each power supply port, thereby realizing the requirement of each power supply port for external independent power supply, and being not affected by other conversion circuits.
Referring to fig. 1, the control circuit 14 is connected to each conversion circuit (for example, the conversion circuits indicated by reference numerals 121, 122, and 123, respectively), and the control circuit 14 is mainly used for controlling the voltage level and/or the power level of the direct current output by each conversion circuit so as to adapt to the electric equipment accessed by the corresponding power supply port. For example, the control circuit 14 may send control commands to the conversion circuit 121 and the conversion circuit 122 respectively, so that the conversion circuit 121 converts the AC commercial power of the AC220V into DC power of DC5V/5W and transmits the DC power to the electric device D1 through the power supply port 131, and so that the conversion circuit 122 converts the AC commercial power of the AC220V into DC power of DC9V/18W and transmits the DC power to the electric device D2 through the power supply port 132.
It should be noted that the conversion circuit in this embodiment may use an AC-DC chip, an AC-DC module or an AC-DC converter that are already available on the market to implement the inversion and rectification functions from AC to DC, and preferably uses a conversion device with adjustable output voltage and output power. Since many manufacturers at home and abroad are producing respective series of AC/DC devices, such as the medium/low power intelligent LDO voltage regulator device introduced by the MPS company in the united states, the specific circuit structure of the converter circuit will not be explained and limited herein.
It should be noted that the control function implemented by the control circuit 14 in the present embodiment can be attributed to the prior art, because the cooperation manner of the control circuit 14 and the AC/DC device is a common circuit composition structure, and it is also a common implementation means that the control circuit 14 outputs the control signal to adjust the output voltage and the output power of the AC/DC device. For example, patent document (CN201920673583.2) discloses a drive circuit of a USB charger and a USB charger, and a USB PD controller in the technical solution performs similar control functions and can perform ac-dc control on an INN3165C ac/dc converter in the drive circuit.
Those skilled in the art will appreciate that the following technical advantages may be realized when applying the multi-port adapter disclosed in the present embodiment: (1) the output ends of the conversion circuits are respectively connected with the power supply ports in a one-to-one correspondence manner, so that each conversion circuit can independently output a path of direct current and supply power to the accessed electric equipment through the corresponding power supply port without being influenced by other conversion circuits, and the power supply efficiency of a single power supply port can be improved; (2) the alternating current commercial power is directly converted into the direct current matched with the electric equipment by using the conversion circuit, so that the complex configuration situation that a DC-DC chip is also used in the conventional direct current adapter device is avoided, the circuit structure is simplified, and the application cost of the adapter is favorably reduced; (3) the control circuit is adopted to control the voltage grade and/or the power grade of the direct current output by each conversion circuit, so that the direct current output by the conversion circuit can be adapted to the electric equipment accessed by the corresponding power supply port, and the intelligent charging of the accessed electric equipment by any power supply port in the multi-port adapter can be realized.
Example II,
Referring to fig. 2, on the basis of the multi-port adapter disclosed in the first embodiment, the present embodiment improves the circuit structure of the multi-port adapter, so that the multi-port adapter 1 not only includes the power-taking port 11, a plurality of converting circuits (such as converting circuits 121, 122, 123), a plurality of power-supplying ports (such as power- supplying ports 131, 132, 133), and the control circuit 14, but also includes at least one switching circuit (such as switching circuits 151, 152).
The switching circuits here each comprise a control terminal, a first terminal and a second terminal, the control terminal of the switching circuit then being connected to the control circuit 14, the first and second terminals of the switching circuit then being connected to the output terminals of the two inverter circuits, respectively. For example, the control terminal of the switching circuit 151 is connected to the control circuit 14, and the first terminal and the second terminal thereof are connected to the output terminal of the inverter circuit 121 and the output terminal of the inverter circuit 122, respectively; the control terminal of the switching circuit 152 is connected to the control circuit 14, and the first terminal and the second terminal thereof are connected to the output terminal of the converting circuit 122 and the output terminal of the converting circuit 123, respectively.
In this embodiment, each of the switch circuits is configured to receive the control signal generated by the control circuit through the control terminal thereof and enable the first terminal and the second terminal thereof to be turned on, so that the direct currents output by the two associated converter circuits respectively perform power combining. For example, the control circuit 14 may send a control signal to the switch circuit 151, and then the switch circuit 151 turns on the first terminal and the second terminal thereof after receiving the control signal, so as to enable the output terminals of the converting circuit 121 and the converting circuit 122 to be communicated, and then the direct currents output by the converting circuit 121 and the converting circuit 122 respectively are combined into a direct current, and the combined direct currents have a common power size and can be output from the power supply port 131 to the electric device D1 or output from the power supply port 132 to the electric device D2.
In one embodiment, the switching circuit (e.g., reference numerals 151, 152) is a field effect transistor (i.e., MOS transistor), a gate of the field effect transistor is used as a control terminal of the switching circuit, and a source and a drain of the field effect transistor are respectively used as a first terminal and a second terminal of the switching circuit. Then, the control circuit 14 can turn on the source and drain of the field effect transistor by sending a level signal to the gate of the field effect transistor. In addition, the switching circuit may also employ a relay, and the control manner of the relay is similar to that of a field effect transistor, and will not be described in detail here.
In another embodiment, if the multi-port adapter 1 includes more than three inverter circuits, the above-mentioned switch circuit may be disposed between the outputs of every two inverter circuits, so that the electric powers output by any two or more inverter circuits can be power-combined.
For example, in the case of the application of three conversion circuits in fig. 3, a switch circuit is provided between each of the conversion circuit 121, the conversion circuit 122, and the output terminals of two conversion circuits, so that a switch circuit 151 is provided between the output terminal of the conversion circuit 121 and the output terminal of the conversion circuit 122, a switch circuit 152 is provided between the output terminal of the conversion circuit 122 and the output terminal of the conversion circuit 123, and a switch circuit 153 is provided between the output terminal of the conversion circuit 123 and the output terminal of the conversion circuit 121. It is understood that this circuit form can combine the electric power output by any two or more than two converting circuits, for example, when the switch circuit 151 is turned on under the control of the control circuit 14, the power combination of the direct current output by each of the converting circuits 121 and 122 can be realized, and the combined direct current can be output through the power supply port 131 or the power supply port 132; for example, when the switch circuit 153 is turned on under the control of the control circuit 14, the power combination of the dc power output by the conversion circuit 121 and the dc power output by the conversion circuit 123 may be realized, and the combined dc power may be output through the power supply port 131 or the power supply port 133; for another example, when the switching circuit 151 and the switching circuit 152 are both turned on under the control of the control circuit 14, the power combining of the dc power output by the conversion circuit 121, the dc power output by the conversion circuit 122, and the dc power output by the conversion circuit 123 may be achieved, and the combined dc power may be output through the power supply port 131, the power supply port 132, or the power supply port 133. That is, the circuit structure can allow a plurality of conversion circuits in the plurality of conversion circuits to combine the direct current power, so that the output is performed through one power supply port, and the realization effect of arbitrary combination output is achieved.
To better understand the technical solutions disclosed in the embodiments, the description is made here with an example. Referring to fig. 2, if the maximum output voltages of the inverter circuits 121, 122, 123 are all 10V and the maximum output power is 50W, for any one of the power supply ports 131, 132, 133, it can output 10V and 50W dc at maximum and supply power to the respective connected electric devices. However, when the switching circuit 151 is turned on by the control circuit 14, the dc power output from each of the inverter circuits 121 and 122 is combined, and the dc power of 10V and 100W can be output through the power supply port 131, thereby matching the power demand of the electric device D1 as much as possible.
As will be understood by those skilled in the art, since the switching circuit is disposed between the output ends of the two conversion circuits, when the switching circuit is turned on, the direct currents output by the two associated conversion circuits can be combined in power, so as to allow the connected electric equipment to be supplied with power in a high-power manner, which contributes to significantly improving the power supply efficiency; in addition, the control circuit detects that one port of the plurality of power supply ports is connected with the power utilization equipment, and the switch circuit is conducted in a time control mode, so that two or more related conversion circuits can efficiently supply power to the connected power supply equipment after power is combined, the defect that the output power of a single conversion circuit is insufficient is overcome, and the power supply problem of the high-power utilization equipment is solved.
Example III,
Referring to fig. 4, on the basis of the multi-port adapter disclosed in the second embodiment, the circuit structure and the circuit type of the multi-port adapter are improved in this embodiment. In this embodiment, the control circuit 14 is further connected to each of the plurality of power supply ports, so that the control circuit can detect the adapted voltage and/or the adapted power of the electrical device connected to each power supply port.
In this embodiment, the control circuit 14 may adopt a charging management chip, and a charging protocol is built in the charging management chip. In order to enable the control circuit 14 to charge the electric equipment connected to the power supply port and achieve a fast and safe charging effect, the control circuit 14 is required to be connected to the power supply port and to perform effective communication with the electric equipment through the power supply port, so that the charging process specified by the charging protocol can be executed on the basis of detecting the power supply state of the electric equipment in real time. It is understood that the control circuit 14 may control the voltage level and/or the power level of the direct current output by each conversion circuit through a built-in charging protocol, and the built-in charging protocol of the control circuit 14 includes one or more of a PD protocol, a QC protocol, and an FCT protocol.
In the present embodiment, the converting circuit is an AC-DC chip, the voltage level of the output direct current comprises various voltages in 3.3-21V, and the power level of the output direct current comprises various powers in 5-100W. The specific voltage level or power level is dynamically adjusted in relation to the power requirements of the powered device and the charging protocol being performed.
In a particular embodiment, with reference to fig. 4, the multi-port adapter 1 comprises two power supply ports 131, 132, two inverter circuits 121, 122 and a switching circuit 151, wherein the output terminals of the two inverter circuits 121, 122 are connected to the two power supply ports 131, 132, respectively, the switching circuit 151 is arranged between the output terminals of the two inverter circuits 121, 122, and the control terminal of the switching circuit 151 is connected to the control circuit 14. In addition, the control circuit 14 may control the first terminal and the second terminal of the switch circuit 151 to be conductive, so that the direct current after power combination is output from one of the power supply ports (such as 131 or 132). Specifically, the control circuit 14 may perform access detection on the power supply ports 131 and 132, and when it is detected that only the electric device D1 is connected to the power supply port 131, the control circuit 14 sends a control signal to the switch circuit 151 to turn on the first terminal and the second terminal of the switch circuit 151, at this time, the direct currents output by the conversion circuit 121 and the conversion circuit 122 are respectively power-combined, and the combined direct current is output from the power supply port 131 to the electric device D1, so that the conversion circuit 121 and the conversion circuit 122 can simultaneously provide the electric device D1 with large power required by circuit operation or charging.
It should be noted that the implementation process of the control circuit 14 detecting the access of the electric device through the port and generating a control signal therefrom belongs to the prior art. For example, when the existing charger supporting the PD protocol is used, after the smart phone is connected to the charger, the charger will automatically communicate with the smart phone, and after it is determined that the smart phone also supports the PD protocol, the port is started to transmit power to the outside, and the power supply voltage and power supply power are increased according to the protocol content, so that the smart phone performs a fast charging mode.
It should be noted that the voltage level and/or the power level of the dc output from the conversion circuit are related to the charging protocol, and proper voltage level and power level are required in different stages of charging to achieve the optimal charging effect. For example, the PD protocol (also referred to as the USB bd fast charging protocol) is a fast charging specification established by the USB-IF organization, and supported by the protocol, the adapter can increase power transmission through a USB cable and a connector, and extend the cable bus power supply capability in USB applications, and the specification can achieve higher voltage and current, transmit power up to 100W, and freely change the power transmission direction. In addition, the QC protocol and the FCT protocol are the prior art and are commonly used in daily life, so they will not be described in detail here.
In the present embodiment, in order to adapt to the charging protocol built in the control circuit 14 and satisfy diversified electric devices, the power supply port may be set as an interface of a USB, miniUSB, microUSB, USB type, HDMI, DP, VGA or DVI type, if the power supply port is in an interface form of a female connector, the accessed electric device should have an interface form of a corresponding male connector, or the accessed power supply line has an interface form of a corresponding male connector.
It should be noted that the charging protocol built into the control circuit 14 is dependent on the type of power supply port, and each charging protocol has different voltage and current, and some charging protocols have multiple gear positions because of the limitation of the interface hardware when the protocol is established. For example, for a PD protocol, the power supply port needs to adopt a USB Type-C interface, and the USB Type-C interface supports 5V/3A by default at maximum, but after the PD protocol is implemented, the output power can be supported to 100W at maximum, so many electric devices using the USB Type-C interface support the PD protocol at present.
Those skilled in the art will appreciate that the following technical advantages may be achieved when utilizing the multi-port adapter disclosed in the present embodiment: (1) the control circuit is internally provided with a charging protocol, so that for a charging type electric device, the conversion circuit in the multi-port adapter can be controlled to rapidly perform voltage adaptation and/or power adaptation, and the aim of efficiently charging the electric device is fulfilled; (2) the power supply port can adopt various types of interfaces, so that most kinds of electric equipment can be connected with the multi-port adapter requiring protection to obtain adaptive direct-current power supply, and the application requirements of multiple occasions are met; (3) due to the serial-parallel configuration function of the conversion circuit, the switching circuit and the power taking port, the multi-port adapter in the application has strong topological capability, the number of power supply ports can be flexibly increased or reduced according to actual needs, and the multi-port adapter has high practical value.
