In the specific implementation manner of the invention, the multiple PD charging devices need to meet the charging requirements of different electric devices at the same time. A single multi-port PD charging device is generally equipped with 2-5USB interfaces, and for the output power of each interface, an output power management circuit is required to uniformly distribute and manage.
The USB TYPEA and TYPEC interfaces are USB information and power transfer interfaces. In the framework, a master TYPEC interface, a slave TYPEA interface and a slave TYPEC interface are classified. The SOC framework consists of a host TYPEC interface and interface control circuit module, and a slave TYPEA/TYPEC interface and interface control circuit module.
The multi-port PD charging equipment comprises a PWM high-frequency power circuit, a host TYPEC interface and interface control circuit module, and a slave TYPEC/TYPEA interface and interface control circuit module. A single multi-port PD charging device is attached with a unique TYPEC host interface and interface control circuit module and one or more TYPEC/TYPEA slave interface and interface control circuit modules. The master TYPEC interface control circuit module and the slave TYPEC/TYPEA interface control circuit module form a control and distribution network, and output electric energy power is uniformly distributed and managed.
The slave TYPEA/TYPEA interface and interface control circuit module is divided into a high-power slave TYPEA/TYPEA interface and interface control circuit module and a low-power slave TYPEA/TYPEA interface and interface control circuit module, and meets different power requirements of electric equipment. The highest output voltage of the small-power slave TYPEC/TYPEA interface is 12V, and the maximum nominal power is 20W. The highest output voltage of the TYPEC/TYPEA interface of the high-power slave machine is 20V, and the maximum nominal power is 100W.
The system comprises a master machine TYPEC interface and interface control circuit module, wherein the only master machine TYPEC interface and interface control circuit module exist in a multi-power multi-configuration full-time-domain PD super fast-charging SOC framework and are used for controlling total output power, controlling bus output voltage, controlling output voltage and power of the master machine TYPEC interface, communicating with a slave machine TYPEA/TYPEC interface and interface control circuit module and distributing power. The host TYPEC interface control circuit module adopts a DC-DC BUCK voltage reduction circuit to adjust the output voltage of the interface.
The main machine TYPEC interface control circuit module is used for controlling the total output power, controlling the output voltage of the bus, controlling the output voltage and power of the main machine TYPEC interface, communicating with the auxiliary machine TYPEC/TYPEA interface control module and distributing power. The host TYPEC interface control circuit module adopts a DC-DC BUCK voltage reduction circuit to adjust the output voltage of the interface.
And the slave TYPEC interface control circuit module is used for controlling the output voltage and power of the slave TYPEC interface, and the communication and receiving power of the master TYPEC interface. And the slave TYPEC interface control circuit module adopts a DC-DC BUCK voltage reduction circuit to adjust the output voltage of the interface.
And the slave TYPEA interface control circuit module is used for controlling the output voltage and power of the slave TYPEA interface, and the communication and receiving power of the master TYPEA interface. And the slave TYPEA interface control circuit module adopts a DC-DC BUCK voltage reduction circuit to adjust the output voltage of the interface.
The main machine TYPEC interface control circuit module controls the PWM high-frequency power circuit and adjusts the total output power and the bus output voltage. The general host TYPEC interface control module controls the output voltage and power of the PWM high-frequency power circuit through an optical coupler signal.
The host TYPEC interface control circuit module has a high priority. For example, in the standby state when no electric equipment is inserted into the slave type electric equipment/type a interface and the type host interface, the output voltage of the control bus of the type host interface and the interface control circuit module is 12V (or 15V or 5V low power consumption mode). When the host TYPEC interface is not connected with the electric equipment, the output voltage is 0V or 5V, and the configuration is specifically based on the actual interface.
The slave TYPEC/TYPEA interface control circuit module communicates with the master TYPEC interface control circuit module through a LINK communication line, and uploads the charging protocol handshake of the slave TYPEC/TYPEA interface and the condition of requesting charging power to the master TYPEC interface control circuit module. And the host TYPEC interface control circuit module is used for uniformly managing and distributing the output electric energy power according to the information uploaded by each slave TYPEC/TYPEA interface control circuit module.
After receiving the output voltage adjustment and output power request sent by the high-power slave TYPEC/TYPEA interface control circuit, the host TYPEC interface control circuit redistributes and adjusts the output voltage and the output electric energy power of the bus after operation. If the bus output voltage is 12V before the output voltage adjustment request is received, the host computer adjusts the bus output voltage to be 20V after responding to the bus output voltage request. The master TYPEC interface control circuit communicates with the requesting slave TYPEC/TYPEA interface control circuit to send power allocation information. And after receiving the corresponding output voltage adjustment and power distribution response, the high-power slave TYPEC/TYPEA interface control circuit adjusts the output voltage and the output power of the corresponding TYPEC/TYPEA interface. If the output voltage required by the high-power slave host TYPEC/TYPEA interface is 20V, after the output voltage of the bus rises to 20V, a DC/DC BUCK circuit in the high-power slave host TYPEC/TYPEA interface and a control circuit thereof is in a LOAD SWITCH state, and power regulation is completed by the master TYPEC/TYPEA interface control circuit. And after the host TYPEC interface control circuit sends power distribution information, the output voltage output power of the corresponding host TYPEC interface is reduced. The main machine TYPEC interface control circuit receives the electric equipment unplugging information sent by the high-power auxiliary machine TYPEC/TYPEA interface control circuit, and the electric energy power is redistributed after operation. If the high-power slave TYPEC/TYPEA interface which requires output voltage regulation is not available in the system, the bus output voltage is reduced, and the bus output voltage is reduced from 20V to 12V. And simultaneously, the output voltage output power of the corresponding host TYPEC interface is improved.
After receiving an output power request sent by a low-power slave TYPEC/TYPEA interface control circuit, the host TYPEC interface control circuit redistributes the output electric energy power after operation. The master TYPEC interface control circuit communicates with the requesting slave TYPEC/TYPEA interface control circuit to send power allocation information. And after receiving the corresponding power distribution information from the slave TYPEC/TYPEA interface control circuit, adjusting the output voltage and the output power of the corresponding TYPEC/TYPEA interface. And after the host TYPEC interface control circuit sends power distribution information, the output voltage output power of the corresponding host TYPEC interface is reduced. The main machine TYPEC interface control circuit receives the electric equipment removal information sent by the low-power auxiliary machine TYPEC/TYPEA interface control circuit, redistributes the output electric energy power after operation, and simultaneously improves the output voltage output power of the corresponding main machine TYPEC interface.
The main machine TYPEC interface and the interface control circuit module are in independent working state (only the main machine TYPEC interface is inserted into the electric equipment, and other auxiliary machine interfaces are in standby state): the main machine TYPEC works in a LOAD SWITCH 100% duty cycle mode when the voltage of the electric equipment is larger than 12V according to the request of the electric equipment, and the voltage (12V-21V) of the electric energy power is dynamically adjusted by a PWM high-frequency power circuit; the electric equipment requests less than 12V to work in a Buck mode, and the electric energy power is fixed at 12V by the voltage of the PWM high-frequency power circuit.
The low-power slave TYPEC/TYPEA interface and interface control circuit module is used for distinguishing the output voltage and power required by the charging equipment after detecting that the electric equipment is inserted, sending an output power request to the master TYPEC interface control circuit, and reducing the bus voltage to the output voltage required by the charging equipment by using a DC/DC BUCK circuit in the slave TYPEC/TYPEA interface control circuit; when the electric equipment is removed, the corresponding slave TYPEC/TYPEA interface control circuit communicates with the master TYPEC interface control circuit to send out an electric equipment removal message. After the electric equipment unplugging message is sent, the low-power slave machine TYPEC/TYPEA interface outputs voltage to return to a standby state (0V or 5V).
The high-power slave TYPEC/TYPEA interface and interface control circuit module distinguishes the output voltage and power needed by the charging equipment after detecting the insertion of the electric equipment, if the output voltage needed by the charging equipment is equal to or lower than 12V, an output power request is sent to the master TYPEC interface control circuit, and the bus voltage is reduced to the output voltage needed by the electric equipment by using a DC/DC BUCK circuit in the slave TYPEC/TYPEA interface control circuit (the condition is the same as the working mechanism of the low-power slave TYPEC/TYPEA interface and the control circuit thereof). If the output voltage required by the electric equipment is higher than 12V, an output voltage adjustment and an output power request are sent to the host TYPEC interface control circuit; when the electric equipment is removed, the corresponding slave TYPEC/TYPEA interface control circuit communicates with the master TYPEC interface control circuit to send out an electric equipment removal message. After the electric equipment unplugging message is sent, the high-power slave machine TYPEC/TYPEA interface outputs voltage to return to a standby state (0V or 5V).
Fig. 1 is a schematic circuit diagram of a system of a multi-port PD charging apparatus. The multi-port charging device in the figure comprises a PWM high-frequency power circuit, a master TYPEC interface and a control circuit thereof, and a plurality of slave TYPEC/TYPEA interfaces and a control circuit thereof. The exemplary multi-port charging device is configured with 5 output interfaces: the system comprises a master TYPEC interface, two slave TYPEC interfaces and two slave TYPEA interfaces. The main machine TYPEC interface control circuit controls the bus output voltage and the total output power of the PWM high-frequency power circuit. Meanwhile, the host TYPEC interface control circuit controls the output voltage and the output power of the host TYPEC interface. The slave TYPEC/TYPEA interface control circuit communicates with the master TYPEC interface control circuit through LINK communication to request output voltage and power or to notify removal of the electrical equipment. And after receiving the communication information of each slave TYPEC/TYPEA interface control circuit, the master TYPEC interface control circuit uniformly manages and distributes the output power of each interface. In a multi-port configuration system, only a single host TYPEC interface, and one or more high-power/low-power TYPEC/TYPEA interfaces may exist simultaneously.
Fig. 2 shows the specific connection of the master TYPEC interface and its control circuit to the slave TYPEC/TYPEA interface and its control circuit. Each slave TYPEC/TYPEA interface control circuit is connected with the PDER pin corresponding to the master TYPEC interface control circuit through a special LINK pin. The slave TYPEC/TYPEA interface control circuit requests the master TYPEC interface control circuit to distribute power after detecting the electric equipment access interface and acquiring the power requirement of the electric equipment through CC1/CC2 or DP/DM communication through the communication between the two pins. After obtaining the approval response of the host TYPEC interface control circuit, the slave TYPEC/TYPEA interface control circuit adjusts the output voltage and the output maximum power. The main machine TYPEC interface control circuit reduces the maximum power output by the main machine TYPEC interface according to the power distribution scheme. The slave TYPEC/TYPEA interface control circuit informs the host TYPEC interface control circuit after detecting that the electric equipment is removed from the interface through the communication between the two pins. The host TYPEC interface control circuit reduces the maximum power allocated to the slave TYPEC/TYPEA interface and increases the maximum power output by the host TYPEC interface.
Fig. 3 is a block diagram of the host TYPEC interface and its control circuit module. The bus output voltage is maintained at 12V or 15V standby voltage when no electric device is connected to each TYPEA/TYPEC. The bus voltage control part mainly determines whether to adjust the output voltage to 20V or 22V according to the voltage requirement of the actual electric equipment of the master TYPEC interface and the voltage requirement of the electric equipment of the slave TYPEA/TYPEC interface. The host TYPEC interface control circuit is provided with a protocol interface, and is communicated with the charging equipment connected with the host TYPEC interface to acquire the output voltage requirement and the output power requirement of the electric equipment. Meanwhile, the host TYPEC interface control circuit is provided with a BUCK voltage reduction module, and when the bus output voltage is higher than the request voltage of the host TYPEC interface charging equipment, the BUCK voltage reduction module reduces the bus output voltage to the request voltage of the interface charging equipment. And if the output voltage of the bus is equal to the voltage requested by the electric equipment of the host TYPEC interface, the BUCK voltage reduction module is in a LOAD SWITCH mode with 100% duty ratio. The power distribution module is responsible for acquiring the power request of the slave interface and then adjusting the maximum output power of the host interface.
Fig. 4 is a block diagram of a TYPEC/TYPEA interface of a high-power/low-power slave and a control circuit module thereof. The protocol interface is responsible for communication of the slave TYPEC/TYPEA interface connected with the electric equipment, and obtains the output voltage requirement and the output power requirement of the electric equipment. Wherein, the TYPEA interface only has a DP/DM communication line. The low-power slave TYPEC/TYPEA interface control circuit only informs the master TYPEC interface control circuit of the power request through the slave interface communication module, and does not request to adjust the output voltage of the bus. If the output voltage request of the electric equipment connected with the high-power slave TYPEC interface control circuit is higher than 12V, the output voltage request and the output power request are simultaneously informed to the control circuit of the master TYPEC interface. And after the main machine TYPEC interface control circuit verifies that the voltage request is valid, the main machine TYPEC interface control circuit adjusts the bus output voltage to 20V or 22V.
The main creative technical characteristic of the scheme is a system framework with 2-5USB output ports, and real-time power distribution and voltage configuration are carried out on each USB output port in the system. In the system architecture, the classification, communication mode and control mode of each USB interface are described in detail, and the number and power limitation of USBA ports and USB TYPEC ports in the architecture can be flexibly configured. In order to realize simultaneous high-voltage output (discharge) of multiple USB ports, a complete power distribution and voltage configuration framework and an auxiliary communication and voltage reduction circuit control mode are designed. The scheme realizes real-time control of discharging of multiple ports with different voltages (can be any voltage of 5V-20V) and different output powers (0-100W), and when multiple USB ports charge equipment at the same time, compared with the case of discharging the multiple ports at the same time of 5V, the charging speed is higher, the control is more intelligent, and the safety is higher.
