Description

一种系统电源
技术领域
本发明涉及车辆控制技术领域，具体是一种用于车辆多个控制模块所需工作电源配送的系统电源。
背景技术
通常的控制模块中所需的工作电源是控制模块本身包含的电源变换实现的，各控制模块均有自己的工作电源变换配置。
随着汽车技术的进步，车辆控制模块向着本地电气智能化、微型化方向发展，控制系统需要较多的控制模块用于车身电器控制；另一方面，汽车输入电源不稳定、汽车电气环境差，这些因素对设置控制模块的工作电源变换装置的技术难度提高，从而带来电源变换复杂度提高、成本上升和可靠性降低。
因此，各控制模块本体设置工作电源的模式较难实现多控制模块的场合、较难使多控制模块微型化，并且控制系统经济性也较差。
发明内容
本发明要解决的技术问题是提供一种系统电源，该系统电源通过一根工作电源线对多个控制模块提供工作电源，省去每个控制模块均要设置单独工作电源的传统模式，从而实现控制系统的低成本和高可靠，并便于实现控制模块的微型化和集成电路化。

本发明的优点：
本发明最少只需设置一个工作电源单元，通过工作电源线和输入电源线，即可实现对多个控制模块配送输入电源和工作电源，无需像通常的对每个控制模块均需配置工作电源。本发明的一种系统电源的主要优势表现在：

图2是本发明的工作电源在高边状态下的系统电压和工作电压的相对关系图。
图3是本发明的工作电源在低边状态下的系统电压和工作电压的相对关系图。
图4是本发明两个含有工作电源单元的控制模块的系统连接图。
图5是工作电源VCC驱动电子开关管的原理图。
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。
一种系统电源，包括有输入电源VB、四个控制模块3、4、5和6、以及线束2，线束2包括有工作电源线21和输入电源线22；每个控制模块的工作电源通过工作电源端口7接入、输入电源通过输入电源端口8接入，工作电源端口7接入到工作电源线21上，输入电源端口8接入到输入电源线22上，输入电源VB接入到输入电源线22上，控制电路板47上设置的自恢复保险丝44的一端连接到工作电源端口7、另一端加载到控制模块的控制电路板的入口点48；四个控制模块3、4、5和6中，控制模块3中包含工作电源单元1，工作电源单元1的输入端与输入电源VB连接，工作电源单元1的输出端输出工作电源VCC并接入到工作电源线21上。
见图1，输入电源VB为蓄电池电源。某些配置下的车辆，输入电源也可以不使用蓄电池电源，由其它电源提供。例如在电动车辆上的输入电源可以由动力电池提供。
见图1，工作电源单元1包括有隔离式DC/DC电源和自恢复保险丝11，隔离式DC/DC电源的正极输入端T2连接输入电源VB，隔离式DC/DC电源的负极输入端T1连接GND(电源地，或搭铁地)，隔离式DC/DC电源的正极输出端T3通过自恢复保险丝11连接到工作电源端口7，隔离式DC/DC电源的负极输出端T4与正极输入端T2接入到输入电源端口8上。
当隔离式DC/DC电源更换为DC/DC变换电源，DC/DC变换电源的正极输入端T2连接到输入电源VB，DC/DC变换电源的负极输入端T1连接GND，正极输出端T3通过自恢复保险丝11连接到工作电源端口7，负极输出端T4与负极输入端T1连接，共用GND(搭铁地)。
控制模块4、5和6不包含工作电源单元，其工作电源由工作电源线21提供，各控制模块均设置工作电源保护装置，工作电源保护装置包含自恢复保险丝、限流电路或自恢复保险丝和限流电路串接组成的保护电路。
见图2，为隔离式DC/DC电源变换的工作电源VCC与输入电源VB的电平电位关系图。
见图3，为DC/DC变换电源变换的工作电源VCC与输入电源VB的电平电位关系图。
见图4，四个控制模块3、4、5和6中，控制模块4和6中均包含工作电源单元，两个工作电源单元的输出端分别串接二极管D2和D4。设置两个工作电源单元的目的是增大电源容量、提高系统的可靠性。
某些控制系统中，为了便于维护工作电源或便于提供工作电源装置，而独立设置工作电源单元。原理图及解释内容略。
本实施例提供的工作电源VCC,在工程实施时综合选取VCC的电平幅值及电子开关管(一般指N型MOS管)的控制极导通电平幅值，使工作电源VCC既能满足控制模块的工作电源需求又能满足控制模块驱动N型MOS管的控制电压需求。
见图5，控制模块4的控制电路板47包括逻辑单元49和驱动单元45，其中逻辑单元49的D1口用来控制电子开关管M1的导通与关断，电子开关管M1的输出连接灯泡LAMP负载。
控制电路板47驱动电子开关管M1的原理：首先，当逻辑单元49在端口D1输出低电平(逻辑单元49的低电平为VB)，三极管T1导通，工作电源端口7连接的工作电源通过自恢复保险丝PTC和三极管T1后加载到电阻R4上，由于自恢复保险丝PTC和三极管T1在正常工作时的电压降较小，所以近似认为控制电压VCC直接加载到电阻R4上，所以电子开关管M1导通工作；当逻辑单元49在端口D1输出高电平(或控制D1为高阻状态)，三极管T1截至，电阻R4的输入端被电阻R3拉为地电平，M1截至、停止工作。
通过工作电源端口7提供给控制模块3、4、5、6工作所需的工作电源满足电子开关管导通的控制需求，不需要再设置驱动电源，从而节约成本和简化结构。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
