Abstract

作为使功率转换系统的电容器的电荷放电的放电控制部的电源包括备用电源，在从该备用电源向负载进行供电的情况下，由于无法应对备用电源或负载变成异常状态的情况，因此，备用电源的输出电压变成异常状态。为了解决该问题，在备用电源或负载发生异常、来自备用电源的供电中检测出异常的情况下，确定异常发生部位，在所确定的异常发生部位为负载的情况下，停止向该负载的供电，从而即使一部分电源供给对象发生异常，也可防止备用电源的输出电压变为异常。

Description

功率转换系统
技术领域
本发明涉及功率转换系统，尤其涉及具备向负载进行供电的备用电源的功率转换系统。
背景技术
车辆中搭载有较多电气设备，在混合动力汽车等车辆中，在可充放电的直流电源与三相交流电动机之间设置有功率转换装置。该功率转换装置包括：对从直流电源提供的直流电压进行升压的升压转换器；对直流电源与升压转换器之间的电压进行滤波的一次滤波电容器；将从升压转换器输出的高压的直流电压转换成交流电压的逆变器；及对升压转换器与逆变器之间的电压进行滤波的二次滤波电容器。
在设置于这种汽车的功率转换装置中，为了防止滤波电容器中储蓄的电荷导致的触电，在碰撞时等事故之际，需要使滤波电容器的电荷放电。然而，在事故的情况下，有时用于进行放电控制的电源发生异常，无法再进行供电。
因而，为了在事故时等必要时可靠地进行滤波电容器的放电控制，提出有包括备用电源的方案。特别在专利文献1中，提出有构成为包括控制滤波电容器的电荷的控制部、将滤波电容器的电荷进行放电的电池、及将滤波电容器的残留电荷提供给控制部的放电电路，将滤波电容器的残留电荷进行电压转换并充电至电池，通过充电至电池来进行滤波电容器的放电，并且，在无法向电池进行充电的情况下，利用放电电路将残留电荷提供给控制部以使控制部的驱动继续。并且，说明了将充电至电池的电能用于其他电气元器件的驱动的情况。
然而，在专利文献1中，虽然记载有将备用电源用于其他电气元器件的驱动的情况，但在专利文献1所示的内容中，并未假定备用电源变成异常状态的情况、或者与该备用电源连接的其他电气元器件变成异常状态的情况，因此，备用电源的输出电压发生异常状态变成新问题。

发明内容
发明所要解决的技术问题
本发明为了应对以上那样的问题，其目的在于提供一种即使在车辆因碰撞等而停止了电源的供给的情况下，也可将滤波电容器中储蓄的电荷快速放电的小型、低成本的功率转换系统。
解决技术问题的技术方案
为了达到上述目的，功率转换系统连接在功率转换用直流电源与电动机之间，其包括：逆变器；电容器，该电容器将所述功率转换用直流电源与所述逆变器之间的端子间电压进行滤波；放电控制部，该放电控制部具有控制所述逆变器的开关动作的逆变器控制部、和向所述逆变器控制部发出指示以将所述电容器的电荷进行放电的放电判定指示部；控制用直流电源，该控制用直流电源作为控制部电源向所述放电控制部进行供电；及备用电源，该备用电源与所述电容器并联连接，在停止来自所述控制用直流电源的供电时向所述放电控制部进行供电，所述备用电源连接有负载，从所述备用电源向所述负载进行供电，在所述备用电源或所述负载发生了异常的情况下，确定异常发生部位，停止向所确定的异常发生部位的供电，从而防止备用电源的输出电压发生异常。
发明效果
在备用电源或负载发生异常、来自备用电源的供电中检测出异常的情况下，确定负载的异常发生部位，停止向发生了异常的负载的供电，从而将向负载停止供电抑制在最低限度，即使在因碰撞导致停止电源供给、负载发生了异常的情况下，也可将滤波电容器中储蓄的电荷快速放电。此外，在没有停止电源供给的情况下，从备用电源向负载进行供电，因此，无需专用电源，可提供小型、低成本的功率转换系统。

实施方式.
图1是表示实施方式所涉及的功率转换系统的结构图。图1中，功率转换系统设置在功率转换用直流电源10与三相交流电动机60之间，包括升压转换器20、逆变器40、二次滤波电容器50、放电控制部70、备用电源80、控制用直流电源81、电源开关82a、82b、82c、负载83a、83b、及电压检测部85。
功率转换用直流电源10可进行充放电，经由逆变器40与三相交流电动机60交换电力。升压转换器20设置在功率转换用直流电源10与逆变器40之间，利用DC/DC转换将从功率转换用直流电源10提供的直流电压进行升压。(在功率转换用直流电源10的输出电压足够的情况下，也可以省略升压转换器20。)一次滤波电容器30连接在功率转换用直流电源10与升压转换器20之间，对功率转换用直流电源10与升压转换器20之间的电压进行滤波。
逆变器40利用DC/AC转换将从升压转换器20输出的高压的直流电压转换成交流电压。二次滤波电容器50连接在升压转换器20与逆变器40之间，对升压转换器20与逆变器40之间的电压进行滤波。
三相交流电动机60通过施加有从逆变器40输出的交流电压，从而控制车辆的驱动力、制动力。
放电控制部70具有转换器控制部71、逆变器控制部72、放电判定指示部73及放电判定部74。放电判定指示部73在由放电判定部74检测出车辆的碰撞时对逆变器控制部72发出指示，以将二次滤波电容器50中储蓄的电荷进行放电。此外，本结构中，若二次滤波电容器50中储蓄的电荷被放电，则同时一次滤波电容器30及能量转移用电容器23中储蓄的电荷也被放电。另外，放电判定部74所进行的车辆碰撞的检测是基于碰撞时产生的车辆的各种状态变化来间接进行的。
转换器控制部71控制图2中示出其结构的升压转换器20中包含的功率半导体元件的结构要素即半导体开关元件21a、21b、21c、21d的开关动作，进行升压转换器20中的DC/DC转换。此外，逆变器控制部72控制图3中示出其结构的逆变器40中包含的开关桥臂的上桥臂侧功率半导体元件44a及下桥臂侧功率半导体元件44b内的半导体开关元件41a、41b、41c、41d、41e、41f的开关动作，进行逆变器40中的DC/AC转换。
在升压转换器20及逆变器40中，功率半导体元件以将半导体开关元件和半导体整流元件彼此反向并联连接得到的结构为单位。此外，将功率半导体元件的串联连接体称为桥臂。
如图2所示，升压转换器20的桥臂中，利用以Si为材料的IGBT，以作为半导体开关元件21a、21b、21c、21d，利用同样以Si为材料的PiN二极管，以作为半导体整流元件22a、22b、22c、22d。
半导体开关元件21a的集电极电极C连接有半导体整流元件22a的阴极电极K，半导体开关元件21a的发射极电极E连接有半导体整流元件22a的阳极电极A，彼此反向并联连接，成为功率半导体元件的一个单位。此处，半导体开关元件21d的发射极电极E与一次滤波电容器30的低电压侧节点N1连接，且与二次滤波电容器50的低电压侧节点N2连接。并且，低电压侧节点N2与逆变器40的下桥臂侧功率半导体元件44b的节点Nu、Nv、Nw连接。
因而，功率转换用直流电源10的低电压侧输出端子、低电压侧节点N1、N2及逆变器40的下桥臂侧功率半导体元件44b的节点Nu、Nv、Nw全部成为相同电位(作为代表，电位Vn)。
另外，半导体开关元件21d的集电极电极C与半导体开关元件21c的发射极电极E及能量转移用电容器23的低电压侧节点连接。半导体开关元件21c的集电极电极C与半导体开关元件21b的发射极电极E及电抗器25的线圈的一端连接。并且，半导体开关元件21b的集电极电极C与半导体开关元件21a的发射极电极E及能量转移用电容器23的高电压侧节点连接。
另一方面，半导体开关元件21a的集电极电极C与二次滤波电容器50的高电压侧节点P2连接。并且，高电压侧节点P2与逆变器40的上桥臂侧功率半导体元件44a的节点Pu、Pv、Pw连接。因而，高电压侧节点P2及逆变器40的上桥臂侧功率半导体元件44a的节点Pu、Pv、Pw全部成为相同电位(作为代表，电位Vp)。
逆变器40如图3所示那样构成。逆变器40内的桥臂设置有与所驱动的三项交流电动机60的相数对应的个数，此处，由U相、V相、W相的3个开关桥臂45a、45b、45c来构成。
逆变器40的U相开关桥臂45a中，利用例如以Si为材料的绝缘栅双极晶体管(IGBT)，以作为半导体开关元件41a、41b，利用同样以Si为材料的PiN二极管，以作为半导体整流元件42a、42b。
半导体开关元件41a的集电极电极C连接有半导体整流元件42a的阴极电极K，半导体开关元件41a的发射极电极E连接有半导体整流元件42a的阳极电极A，彼此反向并联连接，成为功率半导体元件的一个单位。并且，同样地，半导体开关元件41b的集电极电极C连接有半导体整流元件42b的阴极电极K，半导体开关元件41b的发射极电极E连接有半导体整流元件42b的阳极电极A。这样，逆变器40的U相开关桥臂45a将由半导体开关元件41a及半导体整流元件42a构成的功率半导体元件、和由半导体开关元件41b及半导体整流元件42b构成的功率半导体元件串联连接来构成。
另外，逆变器40的V相开关桥臂45b及W相开关桥臂45c也通过由半导体开关元件41c及半导体整流元件42c构成的功率半导体元件、和由半导体开关元件41d及半导体整流元件42d构成的功率半导体元件的串联连接、以及由半导体开关元件41e及半导体整流元件42e构成的功率半导体元件、和由半导体开关元件41f及半导体整流元件42f构成的功率半导体元件的串联连接来构成。另外，逆变器控制部72通过控制逆变器40中包含的开关桥臂45a、45b、45c的上桥臂侧功率半导体元件44a及下桥臂侧功率半导体元件44b内的半导体开关元件的开关动作，调整与三相交流电动机60的连接节点Uac、Vac、Wac的电位，从而控制流向三相交流电动机60的电流量。
其结果，三相交流电动机60进行用于车辆的驱动力、制动力的控制或车辆控制的发电。逆变器控制部72从转速传感器61获取三相交流电动机60的旋转信息。
接下来，对车辆碰撞时的功率转换系统的动作进行说明。首先，放电控制部70在由放电判定部74检测到车辆的碰撞的情况下，使车辆安全停车。
接着，停止来自功率转换用直流电源10的供电，放电判定指示部73对逆变器控制部72指示执行放电动作。按照放电判定指示部73的执行放电动作的指示，逆变器控制部72首先控制逆变器40内的半导体开关元件41a、41b、41c、41d、41e、41f，使二次滤波电容器50的电荷进行放电。
此外，在控制用直流电源81的输出电压正常的情况下，从控制用直流电源81向放电控制部70进行供电。在停止了来自控制用直流电源81的供电的情况下，从备用电源80向放电控制部70进行供电。例如，也可通过将备用电源二极管84a及控制用直流电源二极管84b如图1所示那样进行连接，将备用电源80的输出电压设定为比控制用直流电源81的输出电压要低的值，从而实现上述动作。
备用电源80也向负载83a、83b进行供电。在从放电判定指示部73有执行放电动作的指示的情况下，期望停止向负载83a、83b的供电。进行供电的负载可以是1个或多个。图1中，示出了向2个负载进行供电的情况的示例。
作为备用电源80或负载83a、83b中发生了异常的情况，在来自备用电源80的供电发生异常的情况下，停止所有的负载。另一方面，在负载中发生了异常的情况下，确定异常发生部位，停止向所确定的异常发生部位的供电，从而即使一部分供电对象的负载发生了异常，也可继续向其他负载的供电。
为了确定异常发生部位，优选按照预先设定的顺序来停止供电。另外，停止预先设定的供电的顺序优选为故障率从高到低的顺序。即，故障率较高的负载发生异常的可能性较高，可提前应对异常。
以下，参照图4所示的流程图，对确定异常发生部位的方法进行说明。
对最初进行正常动作的情况进行说明。
首先，开始后，转移至步骤S101，在步骤S101中，从电压检测部85获取备用电源80的输出电压值BV，转移至步骤S102。
步骤S102中，将步骤S101中得到的输出电压值BV与预先设定的规定阈值Vth1及Vth2进行比较。Vth1及Vth2为判定来自备用电源80的供电是否有异常的设定值，Vth1设为最小输出电压值，Vth2设为最大输出电压值。在正常动作的情况下，判定为Vth1<BV<Vth2，转移至步骤S103。
步骤S103中，判定为来自备用电源80的供电正常，转移至步骤S104，结束处理。
接着，对如图1所示在连接有负载83a～83b的结构中备用电源80发生了异常的情况进行说明。此外，为了确定异常发生部位而停止供电的顺序设为负载A83a、负载B83b的顺序。

步骤S200中，按照预先设定的顺序来停止向负载A83a的供电。例如，通过将图1所示的负载A的电源开关82a关断，停止向负载A83a的供电，转移至步骤S201。
在步骤S201中，从电压检测部85获取备用电源80的输出电压值BV，转移至步骤S202。
步骤S202中，将步骤S201中得到的输出电压值BV与预先设定的规定阈值Vth1及Vth2进行比较。在备用电源80有异常的情况下，不判定为Vth1<BV<Vth2，转移至步骤S300。
步骤S300中，仅停止向负载A83a的供电，因此，转移至步骤S200。
步骤S200中，例如在已经关断的负载A用的电源开关82a的基础上，将负载B用的电源开关82b关断，从而停止向负载A83a及负载B83b的供电，转移至步骤S201。
在步骤S201中，从电压检测部85获取备用电源80的输出电压值BV，转移至步骤S202。
步骤S202中，将步骤S201中得到的输出电压值BV与预先设定的规定阈值Vth1及Vth2进行比较。在备用电源80有异常的情况下，不判定为Vth1<BV<Vth2，转移至步骤S300。
步骤S300中，停止向负载A83a及负载B83b的供电。由于停止向负载的所有路径的供电，因此，转移至步骤S301。
步骤S301中，判定为备用电源80的异常，转移至步骤S302，结束处理。此时，优选为，通过将控制部的电源开关82c关断来停止来自备用电源80的供电，通知备用电源的异常。
接着，对连接有4个负载(负载A83a、负载B83b、负载C83c、负载D83d)的结构中3个负载(负载B83b、负载C83c、负载D83d)发生了异常的情况进行说明。此外，将为了确定异常发生部位而停止供电的顺序设为负载A83a、负载B83b、负载C83c、负载D83d的顺序。
首先，开始(步骤S100)后，转移至步骤S101，从电压检测部85获取备用电源80的输出电压值BV，转移至步骤S102。
步骤S102中，将步骤S101中得到的输出电压值BV与预先设定的规定阈值Vth1及Vth2进行比较。在负载B83b、负载C83c、负载D83d有异常的情况下，不判定为Vth1<BV<Vth2，转移至步骤S200。
步骤S200中，按照预先设定的顺序来停止向负载A83a的供电，转移至步骤S201。
在步骤S201中，从电压检测部85获取备用电源80的输出电压值BV，转移至步骤S202。
步骤S202中，将步骤S201中得到的输出电压值BV与预先设定的规定阈值Vth1及Vth2进行比较。在负载B83b、负载C83c、负载D83d有异常的情况下，不判定为Vth1<BV<Vth2，转移至步骤S300。
步骤S300中，仅停止向负载A83a的供电，因此，转移至步骤S200。
通过重复处理上述步骤S200至步骤S300，从而依次停止向负载B83b、负载C83c、负载D83d的供电。
在停止了向负载A83a、负载B83b、负载C83c、负载D83d的供电的状态下，若转移至步骤S202，则判定为Vth1<BV<Vth2，转移至步骤S203。
步骤S203中，将最后停止供电的负载D83d确定作为异常部位，转移至步骤S204。此时，通过对负载D83d异常这一情况进行通知，从而顺畅地应对异常状态。
步骤S204中，开始向判定为异常部位的负载以外的负载的供电，转移至步骤S205。
在步骤S205中，从电压检测部85获取备用电源80的输出电压值BV，转移至步骤S206。
步骤S206中，将步骤S205中得到的输出电压值BV与预先设定的规定阈值Vth1及Vth2进行比较。在负载B83b、负载C83c、负载D83d有异常的情况下，不判定为Vth1<BV<Vth2，转移至步骤S400。在异常部位为一处的情况下，此处判定为Vth1<BV<Vth2，转移至步骤S207，结束处理。
步骤S400中，按照预先设定的顺序来停止向负载A83a的供电，转移至步骤S401。此时，也停止向确定为异常部位的负载D83d的供电。
在步骤S401中，从电压检测部85获取备用电源80的输出电压值BV，转移至步骤S402。
步骤S402中，将步骤S401中得到的输出电压值BV与预先设定的规定阈值Vth1及Vth2进行比较。在负载B83b、负载C83c、负载D83d有异常的情况下，不判定为Vth1<BV<Vth2，转移至步骤S400。
通过重复处理上述步骤S400至步骤S402，从而依次停止向负载B83b、负载C83c的供电。
在停止了向负载A83a、负载B83b、负载C83c、负载D83d的供电的状态下，若转移至步骤S402，则判定为Vth1<BV<Vth2，转移至步骤S403。
步骤S403中，将最后停止供电的负载C83c确定作为异常部位，转移至步骤S404。此时，优选为通知负载C83c的异常。
步骤S404中，开始向判定为异常部位的负载以外的负载的供电，转移至步骤S405。
在步骤S405中，从电压检测部85获取备用电源80的输出电压值BV，转移至步骤S406。
步骤S406中，将步骤S405中得到的输出电压值BV与预先设定的规定阈值Vth1及Vth2进行比较。在负载B83b、负载C83c、负载D83d有异常的情况下，不判定为Vth1<BV<Vth2，转移至步骤S400。
通过重复处理上述步骤S400至步骤S406，从而可确定负载B83b的故障。
并且，在停止了向负载B83b、负载C83c、负载D83d的供电的状态下，若转移至步骤S406，则判定为Vth1<BV<Vth2，转移至步骤S407，结束处理。
在图5中示出确定上述多个负载的异常发生部位的状态。
进行以上处理的结果，如图5所示，判定为负载B83b、负载C83c、负载D83d异常，停止供电，继续进行向负载A83a的供电。
另外，放电控制部70如图6中示出其硬件的一例那样，由处理器700和存储装置701构成。虽未详细图示，存储装置701具备随机存取存储器等易失性存储装置、和闪存等非易失性辅助存储装置。此外，也可具备硬盘这样的辅助存储装置以代替闪存。处理器700执行从存储装置701输入的程序。在此情况下，从辅助存储装置经由易失性存储装置向处理器700输入程序。另外，处理器700可以将运算结果等数据输出到存储装置701的易失性存储装置，也可经由易失性存储装置将数据保存于辅助存储装置。
如以上那样，在备用电源或负载发生了异常的情况下，也确定负载的异常发生部位，停止向所确定的负载的异常发生部位的供电，从而不会出现从备用电源进行供电的所有负载都无法使用的情况，可提供能将滤波电容器中储蓄的电荷迅速放电的小型、低成本的功率转换系统。
另外，在上述实施方式中，说明了从备用电源对多个负载进行供电的情况。在该负载为单数的情况下，同样地，判断是备用电源的异常状态、还是负载的异常状态能够以更简单的步骤来实施。
另外，本发明在其发明的范围内能够将实施方式的任意结构要素适当进行组合、或者适当进行变更或省略。
