总控制模块向子开关电源下发的工作数据包含地址代码；类型分为A代表全部子开关电源，B代表预定义的某组子开关电源，C代表单个子开关电源，上传数据包时一个数据包对应一个子开关电源，根据需要确定数据传送的类组。本发明具体实施例以基于CAN2.0通讯端口，5台并联子开关电源做说明，其它数量、通讯口类似，数据包定义帧起始、地址位、数据位、校验位。帧起始为固定格式，子开关电源接收到数据，都预备接收。地址位以四个为例，进行如下定义，第一台子开关电源定义四个地址，地址1号、地址6号、地址8号，地址9号，第二台子开关电源定义四个地址，地址2号、地址6号、地址8号，地址10号，第三台子开关电源定义四个地址，地址3号、地址7号、地址8号，地址9号，第四台子开关电源定义四个地址，地址4号、地址7号、地址8号，地址10号，第五台子开关电源定义四个地址，地址5号、地址7号、地址8号，地址9号；当需要一个数据包发送一台子开关电源，地址位就直接填地址1号到地址5号中的其中一个，如果需要发送数据
包到某组子开关电源，则地址位就填地址6号或者地址7号，进行全部控制，则地址位就填地址8号，需要控制地址为单的子开关电源，则地址位填9号，需要控制地址为双的子开关电源，地址位就填10号，由于子开关电源处理地址位数据非常快，在数据刚发送完成，下一帧数据只发送一小部分时，就已经知道哪些子开关电源应该动作，做到了子开关电源响应速度的快速提升。数据位为固定格式，根据定义下发需要的数据；校验位为固定格式，用于校验数据的正确与否。如图4所示，起始帧SOF由一位构成，仲裁域ID由11位构成，这就是数据包包含地址信息，如前述，需要全部(8号组)子开关电源刷新数据，则此处写入00000001000，需要编号为单组(9号组)子开关电源刷新数据，则此处写入00000001001；控制域，按标准应用构成；数据域，定为40位，前8位为控制方式，中间16位电流，后面16位为电压；CRC，校验位，按标准应用构成；帧结束，按标准应用构成；根据需要，可增减数据结构。The working data sent by the total control module to the sub-switching power supply includes an address code; the type is divided into A for all sub-switching power supplies, B for a predefined set of sub-switching power supplies, C for a single sub-switching power supply, and one for uploading data packets. The packet corresponds to a sub-switch power supply, and the class of data transfer is determined as needed. The specific embodiment of the present invention is based on the CAN2.0 communication port and five parallel sub-switching power supplies. The other numbers and communication ports are similar. The data packet defines the frame start, address bits, data bits, and check bits. The start of the frame is a fixed format, and the sub-switch power supply receives the data and is ready to receive. The address bits are defined by four examples. The first sub-switch power supply defines four addresses, address 1, number 6, address 8, address 9, address 9, and the second sub-switch power supply defines four addresses, address 2 No., address No. 6, address No. 8, address No. 10, the third sub-switch power supply defines four addresses, address No. 3, address No. 7, address No. 8, address No. 9, and the fourth sub-switch power supply defines four addresses. Address No. 4, Address No. 7, Address No. 8, Address No. 10, the fifth sub-switch power supply defines four addresses, address No. 5, address No. 7, address No. 8, address No. 9; when a packet is required to send a sub-package Switching power supply, the address bit directly fills in one of the address 1 to the address 5, if you need to send data
When a packet is connected to a sub-switch power supply, the address bit is filled with address 6 or address 7 to perform all control, then the address bit is filled with address 8 and the sub-switch power supply with the control address is single, and the address bit is filled with 9 It is necessary to control the sub-switch power supply with the address double, and the address bit is filled with the number 10. Since the sub-switch power supply processes the address bit data very fast, when the data has just been transmitted and the next frame data is only sent a small part, it already knows which The sub-switching power supply should be operated to achieve a rapid increase in the response speed of the sub-switching power supply. The data bits are in a fixed format and the required data is delivered according to the definition; the check digit is a fixed format and is used to verify the correctness of the data. As shown in Figure 4, the start frame SOF consists of one bit, and the arbitration domain ID consists of 11 bits. This is the data packet containing the address information. As mentioned above, all (8-group) sub-switch power supply refresh data is required. Write 00000001000, need to be numbered as a single group (Group 9) sub-switch power refresh data, then write here 00000001001; control domain, according to standard application; data domain, set to 40 bits, the first 8 bits for control mode, The middle 16-bit current, the last 16 bits are the voltage; the CRC, the check digit, is composed according to the standard application; the end of the frame is composed according to the standard application; the data structure can be increased or decreased as needed.
由于下发数据的实时性要求高，采用多种类组传送，各子开关电源响应速度极大的得到提高，特别是子开关电源数量比较多时，其适用范围更广，开关电源快速控制时，一个数据包可以控制从单个子开关电源工作到全部子开关电源工作，实现了并联后的开关电源最小分辨率从单个子开关电源的最小分辨率到子开关电源额定值总和的范围，子开关电源并联后的动态范围控制精度得到很大提升；另一通讯端口用于数据上传，由于接收数据实时要求没有发送那么高，子并关电源发送数据时，根据电源总控制模块要求，使用地址按地址1号到地址5号分时传送，单独两路通讯端口具备互换及备份功能，当其中端口出现故障，另一端口启用应急模式，启用双向通讯模式，这在要求可靠性
高的应用场合，开关电源并联后的可靠性得到提升。Due to the high real-time requirements of the data being sent, the transmission speed of each sub-switching power is greatly improved by using various types of group transmission. Especially when the number of sub-switching power supplies is relatively large, the application range is wider, and when the switching power supply is quickly controlled, one The data packet can control the operation from a single sub-switching power supply to all sub-switching power supplies, achieving the minimum resolution of the switching power supply after paralleling from the minimum resolution of the single sub-switching power supply to the sum of the sub-switching power supply rating, the sub-switching power supply in parallel After the dynamic range control accuracy is greatly improved; another communication port is used for data upload, because the real-time request for receiving data is not sent as high, when the sub-power off data is sent, according to the requirements of the power supply control module, the address is used according to address 1 Number to address 5th time-sharing, separate two-way communication port with interchange and backup function, when the port fails, the other port enables emergency mode, enabling two-way communication mode, which requires reliability
For high applications, the reliability of the switching power supply in parallel is improved.
本发明具体实施例的工作流程如下：The workflow of the specific embodiment of the present invention is as follows:
所有装置上电并进行自检，如有故障，则报出故障，待用户处理；自检通过后，开关电源总控制检测各联机子开关电源，等待用户设置，设置后，启动电源总控制模块，电源总控制模块发送工作要求数据到各子开关电源，然后启动脉冲同步端口和启动/停止端口，子开关电源根据电源总控制模块发送数据和控制端口状态，作出相应处理；开关电源需要停止，电源总控制模块启动/停止端口为停止状态，各子开关电源接收到控制命令后，立即停止子开关电源，同时依照电源总控制模块发出停止指令，各子开关电源作停止命令相关处理。如图5所示，当总控制模块需要输出低纹波方式时，控制子开关电源为错分多相的同步方式；5个子开关电源按地址序号，第一个序号的子开关电源按同步脉冲同步输出，第二个序号的子开关电源按同步脉冲周期的五分之一延时输出，第三个子开关电源按同步脉冲周期的五分之二延时输出，第四个子开关电源按同步脉冲周期的五分之三延时输出，第五个子开关电源按同步脉冲周期的五分之四延时输出，这样，并联后的输出脉冲就填满整个周期，形成直流，输出纹波就很小，多个子开关电源并联方案类似，其它输出方式也采用类似同步控制方法。All devices are powered on and self-tested. If there is a fault, the fault is reported and the user is processed. After the self-test is passed, the switching power supply total control detects the power of each connected sub-switch, waits for the user to set, and after setting, starts the power supply total control module. The power supply total control module sends the work request data to each sub-switch power supply, and then starts the pulse synchronization port and the start/stop port. The sub-switch power supply sends corresponding data according to the power supply total control module and the control port state, and the corresponding processing is performed; the switching power supply needs to be stopped. The power supply total control module start/stop port is in the stop state. After receiving the control command, each sub-switch power supply stops the sub-switch power supply immediately, and simultaneously issues a stop command according to the power supply total control module, and each sub-switch power supply performs a stop command related process. As shown in Figure 5, when the total control module needs to output the low ripple mode, the control sub-switch power supply is a synchronous multi-phase synchronous mode; 5 sub-switch power supplies are according to the address serial number, and the first serial number of the sub-switch power supply is synchronized. Synchronous output, the second serial number of sub-switching power supply is delayed by one-fifth of the synchronous pulse period, the third sub-switching power supply is delayed by two-fifths of the synchronous pulse period, and the fourth sub-switching power supply is synchronized with the pulse. Three-fifths of the period delay output, the fifth sub-switching power supply is delayed by four-fifths of the synchronous pulse period, so that the parallel output pulse fills the entire period, forming a direct current, and the output ripple is small. The parallel schemes of multiple sub-switching power supplies are similar, and other output methods also adopt similar synchronous control methods.
