具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
现有技术中，电力及电子设备中的各种电源需要保证其供电能力的安全性和性能可靠性，例如，随着新能源汽车的普及，新能源汽车充电时的用电安全成为日益关注的问题。汽车充电装置需要一个稳定的电源10供给。若电源10不稳定，尤其当电源10出现短路等情况，则充电时有可能烧毁汽车的重要部件，造成巨大的经济损失，严重时还可能造成人员伤亡，因此电源10电压的稳压控制是急待解决的问题。由此，本发明提供了一种电源稳压输出调节方式，通过闭环PID(比例、积分和微分)控制调节精准控制电源10供电电流的大小，从而实现电源10输出电压的精准控制，可提高电源10输出电压的稳定性，保证充电装置等供电设备的安全性和可靠性。
根据本发明的一个方面，本实施例公开了一种电源稳压输出调节装置。如图1所示，本实施例中，所述电源10根据供电电流形成输出电压。所述装置包括采样模块11、PID调节模块12以及控制模块13。
其中，所述采样模块11用于对电源10的输出电压进行采样得到采样电压。所述PID调节模块12用于基于所述采样电压和预设控制参数通过PID控制调节得到开关频率信号，所述PID控制调节包括电压环控制调节和电压差变化率环控制调节。所述控制模块13用于根据所述开关频率信号形成供电电流。
本发明通过采样模块11对电源10的输出电压进行采样得到采样电压，通过PID调节模块12基于预设控制参数对采样电压进行PID控制调节，得到开关频率信号。从而，可根据PID控制调节后重新生成的开关频率信号形成供电电流，进一步使电源10根据该供电电流形成输出电压。本发明通过对电源10的输出电压进行采样并通过电压环控制调节和电压差变化率环控制调节的PID控制调节调节电源10输出电压的供电电流，从而实现对电源10的实时输出电压进行采集和调节控制以保证电源10稳压输出的 目的。综上，本发明通过闭环PID控制调节精准控制电源10供电电流的大小，实现电源10输出电压的精准控制，提高了电源供电的稳定性。
在优选的实施方式中，所述采样模块用于对电源的输出电压进行采集得到采样电压。其中，采集的方式包括通过分压采集、通过霍尔效应采集和通过分压芯片采集中的至少一种。在实际应用中，还可通过其他方式对输出电压进行采集得到采样电压，本发明对此并不作限定。为了实时采集电源10的输出电压并降低信号处理的复杂度，在一个优选的实施方式中，所述采样模块11用于对电源10的输出电压进行分压得到采样电压。具体的，通过分压方式，对电源10的输出电压进行按比例采集，从而采集得到的采样电压既可以表征电源10输出电压的大小，在后续电压或电流信号处理过程中，由于采样电压为按一定比例采集的输出电压的一部分，将输出电压的大电压转换为小电压，从而后期处理的信号量较小，通过简单电路即可实现电源10输出电压的稳压调节，对于电路器件的要求也不高。
作为一种优选的实施方式，所述采样模块11包括第一电阻器组、第二电阻器组、电容器C1和模数转换器ADC，所述第一电阻器组和第二电阻器组包括至少一个电阻器，若所述电阻器为多个，其中至少两个电阻器依次串联连接或者至少两个电阻器并联后与其他电阻器串联连接。
其中，所述第一电阻器组的第一端与电源10的信号输出端OUT1连接，所述信号输出端用于输出所述输出电压，第二端与所述第二电阻器组的第一端、电容器C1的第一端和所述模数转换器ADC分别连接。所述模数转换器ADC用于输出采样电压。第二电阻器组的第二端和电容器C1的第二端分别接地GND。
可以理解的是，第一电阻器组和第二电阻器组对电源10的输出电压进行分压，经过第一电阻器组的压降后得到模拟量的采样电压并传输至模数转换器ADC。模数转换器ADC将模拟量的采样电压转换为数字量的采样电压后传输至PID调节模块12进行PID控制调节。其中，分压得到的采样电压的电压值可根据第一电阻器组、第二电阻器组的电阻值和输出电压得到，且第一电阻器组和第二电阻器组的电阻值本领域技术人员可根据实际需求灵活设置，以实现调节采样电压的目的，本发明对此并不作限定。
在一个具体例子中，如图2所示，所述采样模块11包括第一电阻器组、第二电阻器组、电容器C1和模数转换器ADC。其中，第一电阻器组包括第六电阻器R6、第七电阻器R7和第八电阻器R8。第二电阻器组包括第九电阻器R9。其中，第六电阻器R6、第七电阻器R7和第八电阻器R8依次串联后接入采样模块11中。即第六电阻器R6的第一 端与电源10的信号输出端OUT1连接，第二端与所述第七电阻器R7的第一端连接。第七电阻器R7的第二端与所述第八电阻器R8的第一端连接，所述第八电阻器R8的第二端与所述第九电阻器R9的第一端、电容器C1的第一端和所述模数转换器ADC分别连接。所述第九电阻器R9的第二端接地GND。其中，第一电阻器组采用多个电阻器串联的形式，一方面可增大第一电阻器组的电阻值，降低采样电压的大小以便于处理，另一方面，采用多个电阻器串联的方式也避免了采用一个大电阻器带来的体积大的问题。
在优选的实施方式中，为了实现精确的PID控制调节，所述预设控制参数包括目标电压，所述PID调节模块12包括用于电压环控制调节的电压环控制器和用于电压差变化率环控制调节的电压差变化率环控制器。优选的，PID调节模块12可通过微控制器(MCU)实现。
其中，所述电压环控制器用于根据所述目标电压和采样电压得到实际电压差，并根据所述实际电压差得到电压变化率控制幅度。
所述电压差变化率环控制器用于根据电压变化率控制幅度得到目标电压变化率，根据实际电压差得到实际电压变化率，并根据所述目标电压变化率和实际电压变化率得到开关频率信号。
在一个可选的实施方式中，可针对采样电压设置对应的目标电压，实际电压差为目标电压和实时采集的采样电压之差。在其他实施方式中，也可以针对采样电压对应的电源10输出电压设置对应的目标电压，则实际电压差为目标电压和对采样电压进行换算后得到的输出电压之差。其中，可根据采样电路中采样电压与第一电阻器组和第二电阻器组的电阻值以及输出电压之间的关系对采样电压进行换算。并且以上两种方式得到的电压差需设置对应的PID调节模块12的PID控制调节算法对输入的电压差进行调节得到开关频率信号，本领域技术人员可根据实际需求进行相关的设定，本发明在此不再赘述。
为了提高PID控制调节的精度，本实施例中，对模数转换器ADC输出的数字量的采样电压进一步进行电压转换得到实际的输出电压。PID调节模块12进一步根据得到的输出电压和预设控制参数通过PID控制调节得到开关频率信号。
所述电压环控制器用于根据所述目标电压和采样电压得到实际电压差，并根据所述实际电压差得到电压变化率控制幅度，即电压环控制器可实现电压环控制调节。在一个具体例子中，电压环控制器可通过以下PID控制调节算法计算得到电压变化率控制幅度。
Figure PCTCN2021105194-appb-000001
其中，Q(t)为t时刻电压变化率控制幅度，k p为电压环控制器的比例项修正系数，k i为电压环控制器的积分项修正系数，k d为电压环控制器的微分项修正系数，e c(t)为给定的目标电压Vdt与实际检测的输出电压Vt之差，即e c(t)＝(Vt-Vdt)
Pd(t)＝(Q(t)-Q(t-1))/dt
其中，Pd(t)为t时刻的目标电压变化率，Q(t)为t时刻电压变化率控制幅度，Q(t-1)为t-1时刻电压变化率控制幅度，dt为PID调节周期。
所述电压差变化率环控制器用于根据电压变化率控制幅度得到目标电压变化率，根据实际电压差得到实际电压变化率，并根据所述目标电压变化率和实际电压变化率得到开关频率信号，即电压差变化率环控制器可实现电压差变化率环控制调节。在一个具体例子中，将所目标电压变化率与所述实际电压变化率之差输入电压差变化率环控制器，电压差变化率环控制器可通过以下PID控制调节算法计算得到开关频率信号。
Figure PCTCN2021105194-appb-000002
其中，P(t)为开关频率信号，k i-p为电压差变化率环控制器的比例项修正系数，k i-i为电压差变化率环控制器的积分项修正系数，k i-d为电压差变化率环控制器的微分项修正系数，e p(t)为给定的目标电压变化率与所述实际电压变化率之差。实际电压变化率＝e c(t)/dt。需要说明的是，对于本实施例中的各系数，本领域技术人员可根据经验选取，本发明对此并不作限定。
在优选的实施方式中，所述控制模块13包括开关元件Q。所述控制模块13用于根据所述开关频率信号控制所述开关元件Q导通和断开电源端VDD和供电电流输出端OUT2间的通路形成供电电流。可以理解的是，可根据开关频率信号控制开关元件Q的导通或断开，控制电源端VDD的电流是否输出，以形成供电电流，调节电源10的输出电压。
在一个具体例子中，控制模块13可通过具体的电路结构实现。具体的，如图3所示，所述控制模块13包括第三电阻器R3、第四电阻器R4和开关元件Q，该第三电阻器R3和第四电阻器R4可实现限流功能。
其中，所述第三电阻器R3的第一端用于接收所述开关频率信号，第二端与所述开关元件Q的控制端G连接。所述开关元件Q的第一端D与电源端VDD连接，第二端S与所述第四电阻器R4的第一端和所述供电电流输出端OUT2分别连接。所述第四电阻器R4的第二端接地GND。
可以理解的是，以第一电平为高电平，第二电平为低电平，开关元件Q为NMOS为例对该具体例子的工作原理进行说明。其中，需要说明的是，本实施例中以第一电平为高电平，第二电平为低电平，开关元件Q为NMOS为例进行说明。在实际应用中，通过对各模块进行电路结构的灵活设置，第一电平也可以是低电平，从而第二电平是高电平，开关元件Q也可以选用PMOS或其他可实现相同功能的开关元件Q，本发明对此并不作限定。由此，其他与本发明具有相同的发明构思的技术方案也理应在本发明的保护范围内。
当开关频率信号为高电平时，开关元件Q响应于高电平而导通，则电源端VDD与供电电流输出端OUT2导通，在电源端VDD的作用下，供电电流输出端OUT2输出供电电流至电源10以使电源10输出对应的输出电压。当开关频率信号为低电平时，开关元件Q响应于低电平处于断开状态，则电源端VDD与供电电流输出端OUT2断开，供电电流输出端OUT2无输出。从而，本发明通过PID控制调节根据电源10的输出电压得到开关频率信号，通过开关频率信号控制供电电流的输入，进而实现调节电源10输出电压的目的，保证电源的稳压输出。
在优选的实施方式中，所述控制模块13进一步包括第五电阻器R5。其中，所述第五电阻器R5的第一端与所述第三电阻器R3的第二端和所述开关元件Q的控制端分别连接，所述第五电阻器R5的第二端接地GND。
可以理解的是，控制模块13进一步包括第五电阻器R5，该第五电阻器R5为抗干扰的下拉电阻。即当开关频率信号存在干扰出现电压浮动时，第五电阻器R5可以一定程序上降低存在干扰的开关频率信号的电压值，将开关频率信号的电压值尽量拉低至开关元件Q的阈值电压以下，防止开关元件Q误导通，增强控制模块13的抗干扰强度。
需要说明的是，本领域技术人员能够明了，本实施例中的开关元件Q可采用晶体管，包括N型晶体管和P型晶体管，各种信号的高低电平是与晶体管的型号配合才能实现对应的功能。本领域技术人员能够知晓使得P型晶体管导通需要配合低电平信号，使得N型晶体管导通需要配合高电平信号，从而采用N型晶体管或P型晶体管并设置晶体管栅极(控制端)的电平以实现相应的导通或断开功能，从而实现本发明的数据读取目 的。本发明实施例提供的晶体管的第一端可以为源极，则第二端为漏极，或者反之亦然，本发明对此不作限定，可根据晶体管的类型合理选择即可。
此外，本发明实施例提供的晶体管可以为场效应晶体管，其中可以为增强型场效应晶体管，也可以为耗尽型场效应晶体管，本发明对此并不作限定。
