技术领域technical field
本发明涉及电源技术领域，特别涉及一种电源模块的输出电压调节方法和装置。The invention relates to the technical field of power supplies, in particular to a method and device for adjusting the output voltage of a power supply module.
背景技术Background technique
电源模块是一种恒流源或恒压源，用于为设备中的电路模块、芯片或电子元器件供电，一般由厂商设计制造做成成品出售。The power module is a constant current source or constant voltage source, which is used to supply power to the circuit modules, chips or electronic components in the equipment. It is generally designed and manufactured by the manufacturer and sold as a finished product.
如图1所示，传统DC/DC电源模块用于将输入电压转换为一个固定的直流电压输出，用户只能通过串联相应的电阻来调整输出电压，一旦使用固定阻值的电阻R1，VOADJ的输出电压即恒定。而在实际应用中，有些器件需要动态调整输出电压，而且，在对电路器件进行供电时，各模块、各电路、各芯片所需要的电压又各不相同，需要能随时改变输出的电压。如果电源模块无法调整输出电压，会限制电源模块的使用范围，也无法满足人们对能动态输出电压的元器件的需求。As shown in Figure 1, the traditional DC/DC power module is used to convert the input voltage into a fixed DC voltage output. The user can only adjust the output voltage by connecting the corresponding resistors in series. Once the fixed resistance resistor R1 is used, VOADJ The output voltage is constant. In practical applications, some devices need to dynamically adjust the output voltage. Moreover, when powering circuit devices, the voltages required by each module, each circuit, and each chip are different, and the output voltage needs to be changed at any time. If the power module cannot adjust the output voltage, the scope of use of the power module will be limited, and people's demand for components that can output voltage dynamically cannot be met.

本发明目的的实现及其功能、原理将在具体实施方式中结合附图作进一步阐述。The realization of the purpose of the present invention and its functions and principles will be further elaborated in the specific embodiments in conjunction with the accompanying drawings.
具体实施方式Detailed ways
下面结合附图及具体实施例做进一步说明。Further description will be made below in conjunction with the accompanying drawings and specific embodiments.
实施例一：Embodiment one:
本实施例首先提供一种电源模块的输出电压调节方法，如图2所示，所述电源模块为直流DC/DC恒压源，具有一电压输出端VOADJ，用于输出一恒定的电压，在使用时，在电压输出端VOADJ串接一第一电阻R1进行输出，为后面的电路或电子元器件供电。This embodiment firstly provides a method for adjusting the output voltage of the power module. As shown in FIG. 2 , the power module is a DC/DC constant voltage source and has a voltage output terminal VOADJ for outputting a constant voltage. When in use, a first resistor R1 is connected in series at the voltage output terminal VOADJ to output power for subsequent circuits or electronic components.
本实施例的调节方法主要包括以下步骤：The adjustment method of this embodiment mainly includes the following steps:
S1：配置一DA转换器，所述DA转换器通过第二电阻连接到所述电压输出端；S1: configure a DA converter, the DA converter is connected to the voltage output terminal through a second resistor;
S2：配置一控制器，连接到所述DA转换器的控制端，并控制所述DA转换器输出一可变电压。S2: configuring a controller, connected to the control terminal of the DA converter, and controlling the DA converter to output a variable voltage.
本实施例可选用AD5300作为DA转换器，该DA转换器主要由数字寄存器、模拟电子开关、求和运算放大器和基准电压源(或恒流源)VCC组成，经VOUT端输出一个电压，并通过第二电阻R2连接到电源模块的VOADJ端，与VOADJ端输出的电压并联后，经第一电阻R1对外供电。In this embodiment, AD5300 can be selected as the DA converter. The DA converter is mainly composed of a digital register, an analog electronic switch, a summation operational amplifier and a reference voltage source (or constant current source) VCC, and outputs a voltage through the VOUT terminal, and It is connected to the VOADJ terminal of the power module through the second resistor R2, and after being connected in parallel with the output voltage of the VOADJ terminal, it supplies power to the outside through the first resistor R1.
此外，上述控制器与DA转换器的控制端连接，用于控制DA转换器的输出数字寄存器，使VOADJ端的输出电压可变。In addition, the above-mentioned controller is connected with the control terminal of the DA converter, and is used to control the output digital register of the DA converter, so that the output voltage of the VOADJ terminal can be changed.
具体地，设电源模块的VOADJ端的输出电压为Vfb，输出电流为I1，DA转换器的VOUT端的输出电压为Vdac，Vdac和Vfb的压差会产生输出电流I2，并且满足：Specifically, assuming that the output voltage of the VOADJ terminal of the power module is Vfb , the output current is I1 , the output voltage of the VOUT terminal of the DA converter is Vdac , and the voltage difference between Vdac and Vfb will generate an output current I2 , and satisfy:
I2＝(Vdac-Vfb)/R2； (1)I2 =(Vdac -Vfb )/R2; (1)
I3＝Vfb/R1； (2)I3 =Vfb /R1; (2)
根据电路原理，对外供电的总电流I3＝I1+I2(3)According to the circuit principle, the total current I3 for external power supply = I1 +I2 (3)
(1)(2)(3)三式联立，得出Vdac＝Vfb+(R2Vfb-I1R1R2)/R1，其中，I1，Vfb，R1和R2是已知的，故可以算出Vdac的值。(1)(2)(3) Combining the three formulas, it can be obtained that Vdac = Vfb + (R2Vfb -I1 R1R2)/R1, where I1 , Vfb , R1 and R2 are known, so The value of Vdac can be calculated.
上述控制器可以是板载CPU，包括单片机或MCU芯片，其通过串行总线接口与DA转换器的控制端连接，实现对DA转换器的控制。The above-mentioned controller can be a board-mounted CPU, including a single-chip microcomputer or an MCU chip, which is connected to the control terminal of the DA converter through a serial bus interface to realize the control of the DA converter.
此外，本实施例还包括步骤：In addition, this embodiment also includes the steps of:
S3：配置一反馈电路，所述控制器通过所述反馈电路实时修正所述DA转换器的输出电压。S3: configuring a feedback circuit, the controller corrects the output voltage of the DA converter in real time through the feedback circuit.
该反馈电路用于检测上述电流I3或电压Vdac，并反馈给控制器，控制器分析上述电流I3或电压Vdac的实际值与目标值的差值，调整对DA转换器的配置参数，直至其实际值与目标值相同。The feedback circuit is used to detect the above-mentioned current I3 or voltage Vdac and feed it back to the controller. The controller analyzes the difference between the actual value of the above-mentioned current I3 or voltage Vdac and the target value, and adjusts the configuration parameters of the DA converter , until its actual value is the same as the target value.
进一步地，本实施例还可采用映射表的方式进行自动电压调节管理，以便动态输出不同芯片或电器元器件所需的电压。可采用以下步骤执行：Further, in this embodiment, the automatic voltage regulation management can also be performed in the form of a mapping table, so as to dynamically output voltages required by different chips or electrical components. This can be done using the following steps:
S4：向CPU加载映射表，使所述CPU根据所述映射表自动调节所述DA转换器的输出电压。S4: Load a mapping table to the CPU, so that the CPU automatically adjusts the output voltage of the DA converter according to the mapping table.
具体地，上述步骤S4进一步包括：Specifically, the above step S4 further includes:
S41：根据芯片的电气特性生成映射表，所述映射表包括芯片型号和与之对应的工作电压；S41: Generate a mapping table according to the electrical characteristics of the chip, the mapping table includes a chip model and a corresponding working voltage;
S42：根据所述映射表生成相应的脉冲序列；S42: Generate a corresponding pulse sequence according to the mapping table;
S43：将所述脉冲序列按需输入所述CPU，使所述CPU根据所述脉冲序列获取对应芯片的工作电压，并调节所述DA转换器的输出电压，为所述芯片供电。S43: Input the pulse sequence into the CPU as required, so that the CPU obtains the working voltage of the corresponding chip according to the pulse sequence, and adjusts the output voltage of the DA converter to supply power for the chip.
例如：芯片1的型号为001，其工作电压为1V；芯片2的型号为002，其工作电压为1.04V；……芯片N的型号为00N，其工作电压为0.9V，则生成下述映射表：For example: the model of chip 1 is 001, and its operating voltage is 1V; the model of chip 2 is 002, and its operating voltage is 1.04V; ... the model of chip N is 00N, and its operating voltage is 0.9V, then the following mapping is generated surface:
其中，D1～DN为各脉冲序列对应于CPU的输入端引脚。当需要为芯片1供电时，脉冲序列输入对应的D1引脚，CPU会根据D1引脚预先设计的参数获取到所需供电的芯片为001型芯片，其工作电压为1V，此时，会调节DA转换器的寄存器，使其输出电压满足Vdac＝Vfb+(R2Vfb-I1R1R2)/R1的条件，其中，Wherein, D1 -DN are the input terminal pins corresponding to the CPU foreach pulse sequence. When it is necessary to supply power to chip 1, the pulse sequence is input to the corresponding D1 pin, and the CPU will obtain the required power supply chip according to the pre-designed parameters of the D1 pin is a 001 chip, and its working voltage is 1V. Adjust the register of the DA converter so that its output voltage satisfies the condition of Vdac =Vfb +(R2Vfb -I1 R1R2)/R1, where,
Vfb＝1，联立上式，可得Vdac＝1+(R2-I1R1R2)/R1。Vfb =1, and the above formula can be combined to get Vdac =1+(R2-I1 R1R2)/R1.
以此类推，可分别得出为芯片2～芯片N供电时，DA转换器的输出电压。By analogy, the output voltages of the DA converters when supplying power to chips 2 to chip N can be obtained respectively.
这便于实现自动控制，本实施例还配置一存储器，该存储器挂载于上述CPU，并用于存储所述映射表，这样，当需要为某一芯片供电了，自动从存储器中读取该映射表，再利用DA转换器输出所需的电压即可。This facilitates the realization of automatic control. This embodiment also configures a memory, which is mounted on the above-mentioned CPU and used to store the mapping table. In this way, when a certain chip needs to be powered, the mapping table is automatically read from the memory. , and then use the DA converter to output the required voltage.
可见，通过上述方法，可以实现对电源模块的输出电压进行调节，至于调节范围，若电源模块的输出功率较大，则可实现对输出电压的微调。It can be seen that through the above method, the output voltage of the power module can be adjusted. As for the adjustment range, if the output power of the power module is relatively large, the output voltage can be fine-tuned.
