Abstract
本发明涉及电流可逆DC/DC双升压平方转换器,该转换器能够实现高变换比。
Description
技术领域
本发明涉及DC/DC电压转换器,换言之,涉及被设计为维持在两个电压源之间的能量流量的系统。特别地,本发明可用于对应于平均和高功率应用的通常称为斩波器(chopper)的转换器类型。
从电路的角度来看,这种类型的转换器可以被认为是直接电量变换器。有两个定义DC/DC转换器类型的基本变量:
-如果输出电压小于输入电压,那么其称为降低(step-down)DC/DC转换器或“降压(buck)”转换器,
-如果输出电压大于输入电压,那么其称为升高(step-up)DC/DC转换器或“升压(boost)”转换器。
对于这种类型的转换器,当在转换器的工作期间输入或输出电流可以在两者中的任一方向上时,使用术语双向电流。
背景技术
DC/DC升高或升压转换器特别地用于电动和混合动力车辆。它们通过增加或减少在DC总线端子的电压来连接电池电压和电马达逆变器的DC总线。它们也可以用于在逆变器的输入端耦接电池和超级电容。
图1是示出了用于电动或混合动力车辆的电转换系统。参考标号1表示在A点和B点之间输出电压U的电池。逆变器2的输入端连接在A点和B点之间。逆变器2的输出给车辆的三相电马达3供电。DC/DC转换器4构成第一的A点和B点与第二的超级电容5之间的连接。在本附图中I电池表示电池电流,I超级电容表示在超级电容中的电流。
在本领域中的DC/DC转换器的使用具有多个优点。它们使得能够管理在逆变器的DC总线和能量存储系统之间的能量流动。它们使得能够使用低电压电池。它们使得能够使用具有非常高的DC总线电压的逆变器(高速机械)。它们使得速度能够大范围地变化。它们给出电转换系统的更好的总效率。
混合动力和电动车辆的趋势导致逆变器DC总线上日益增高的电压。该趋势的优点是减少了斩波器线圈的截面并且减少了电机的尺寸。但是这需要使用DC/DC转换器来升高电池电压。
DC/DC升压型转换器的第二用途包括耦接机载能量存储装置。例如,耦接电池(能量)和超级电容(功率)。
当仅有的能量源是电池时,当负载可以在非常短的时间内吸收或输出高电流时(例如,在车辆的加速或刹车期间),很难维持DC总线上的电压。因此,可以在正和负峰值电流期间察觉到由安装在具有混合动力马达驱动的车辆上的电池输出的电压波动。这是因为实际上电池旨在(并且通常设置尺寸为)提供电能量(额定功率)而非瞬时功率。电池也不能在非常短的时间间隔内单独吸收全部的刹车能量。单独使用电池(电压不稳定)会加速老化。实际上结合超级电容(设置为用于功率的尺寸)可以在电池的全部工作范围期间减少电池电压波动以及利用在刹车期间可用的全部电能量。
如果DC/DC转换器用于耦接电池和超级电容,那么电池影响转换器的输出电压。直接以电流来控制转换器从而在加速期间提供功率峰值或在刹车时吸收电流峰值。因为超级电容的电压可以下降50%(从而使用超级电容充电的75%),所以所使用的DC/DC转换器必须是电流可逆升压型。
在应用的电动或混合动力车辆类型中,对DC/DC转换器的典型的规定将对DC电压施加可忽略的脉动比(少于3%)。然后,转换器的基本结构与设计为调适电源(电流/电压)且用于滤波的线性元件(感应线圈、电容器)相结合。
图2是示出了安装在Lexus混合动力车上的RX400h马达上使用的电转换系统的示图。参考标号11指代连接至电流可逆DC/DC升压转换器12的输入端的288V电池,该电流可逆DC/DC升压转换器12在电阻13和平滑电容器14的端子上输出650V的输出电压。转换器的输出电压给第一逆变器15和第二逆变器16供电。逆变器15和16的输入端设置有滤波电容器17和18。逆变器15对马达19输出AC供电电压同时逆变器16复原由马达20产生的电流。
转换器12在滤波电容器21的端子接收来自电池11的电压。该电压通过感应线圈22传输至IPM(智能功率模块)23。
图3A和图3B是示出了变换器12(电流可逆DC/DC升压转换器)的输入电压的变换比的变化和转换器的效率ρ(纵坐标)相对于循环比(cyclic ratio)RC(横坐标)的示图。图3A和图3B中示出的曲线由这种类型的装置(传导、切换并且在无源组件中)中的建模损失(modelling loss)绘制。对40kW的功率转换器进行计算(200V的输入电压和由控制信号的循环比控制的输出电压)。图3A和图3B中的曲线示出了转换器的效率随着电压变换比的增加而减少。控制信号的循环比对应于被转换器的斩波周期除的控制脉冲的持续时间。该比值在0到1的范围内变化。
总之,当试图耦接机载能量源时,目的是在不改变效率的条件下减小机载装置的尺寸、重量和成本。当超级电容耦接至电池时,该耦接必须不产生任何比简单地在电池中添加额外的单元更严格的尺寸、成本和重量的限制。换言之,超级电容的电压必须低于电池电压。例如,如果超级电容的电压等于电池电压的一半,那么标准可逆升压转换器能够以92%量级的效率来使用。然而,如果需要使用超级电容的全部充电范围,那么转换器将具有低得多的效率(80%的量级)。如果需要达到50%的超级电容电压,那么多于4的电压变换比是必须的。该问题在超级电容的额定电压较低时是特别重要的。
发明内容
为了克服上述现有技术的问题,提出了一种新型DC/DC升压型转换拓扑,其能够在效率完全相同的条件下实现比根据现有技术的装置更高的变换比。该新型装置可以称作“电流可逆双升压平方DC/DC转换器”。
因此,本发明的目的是将用作在第一DC电压源和第二DC电压源之间的接口的电流可逆DC/DC升压转换器,第一DC电压源的电压小于第二DC电压源的电压,转换器的拓扑由以下支路组成:
-第一支路,连接第一DC电压源和第二DC电压源的正极,包括从第一DC电压源到第二DC电压源串联的第一感应线圈、以断开和闭合控制的第一开关、第二感应线圈、以断开和闭合控制的第三开关;
-第二支路,连接第一DC电压源和第二DC电压源的负极;
-第三支路,并联地连接至串联的第一开关和第二线圈,包括阳极在第一电压源的正极侧的二极管;
-第四支路,连接在第二支路和位于第一感应线圈和第一开关之间的部分第一支路之间,包括阳极在第二支路侧的第二二极管;
-第五支路,连接在第二支路和位于第一开关和第二感应线圈之间的部分第一支路之间,包括第一电容器;
-第六支路,连接在第二支路和位于第二感应线圈和第三开关之间的部分第一支路之间,包括以断开和闭合控制的第二开关;
-第七支路,并联地连接到DC电压源上,包括第二电容器;
该转换器包括控制开关的装置,以便:
-当电流在转换器中在从0到T变化的控制周期期间以循环比α从第一电压源向第二电压源流通时:
·从t=0到时间t=αT,其中0<α<1,第一开关和第三开关断开而第二开关闭合;
·从t=αT到时间t=T,第一开关和第三开关闭合而第二开关断开;
-当电流在转换器中在从0到T变化的控制周期期间以循环比α从第二电压源向第一电压源流通时:
·从时间t=0到时间t=αT,其中0<α<1,第一开关和第三开关闭合而第二开关断开;
·从时间t=αT到时间t=T,第一开关和第三开关断开而第二开关闭合;
优选地,循环比α在0.25和0.75之间。
优选地,以断开和闭合来控制的开关是从MOSFET和IGBT中选择的具有并联安装的二极管的组件。

具体实施方式
图4是示出了根据本发明的电流可逆双升压平方转换器的拓扑的示图。该图中示出的转换器形成在末端(点C和D)接收输入电压U输入的超级电容5和其间具有输出电压U输出的点A和B(参见图1)之间的连接。
第一感应线圈L1、第一开关Q1、第二感应线圈L2和第三开关Q3串联地连接在点C和点A之间。在点D和点B之间的连接接地。
二极管D1并联地连接到串联安装的元件Q1和L2上。二极管D1的阳极在点C的同一侧,它的阴极在点A的同一侧。
二极管D2连接在地与元件L1和Q1之间的连接之间。二极管D2的阳极接地。
电容器C1连接在地与元件Q1和L2之间的连接之间。电容器C2连接在点A和点B之间。
第二开关Q2连接在地与元件L1和Q3之间的连接之间。
开关Q1、Q2和Q3是具有反并联安装的二极管的以断开和闭合来控制的MOSFET或IGBT型的开关。
图5是示出了根据本发明的作为对于转换器的时间t的函数的控制信号的循环比的原理的示图。开关Q1和Q3由称作Cmd1的同一控制信号来控制。开关Q2由与Cmd1互补的控制信号Cmd2来控制。图5中的示图示出了在单个控制周期T内控制信号的循环比α的原理。
感应线圈L1和L2分别具有r1和r2的内阻。与在点A和点B之间的负载相等的阻抗称为R。控制脉冲的时长(由循环比α表示)控制转换器的变换比。输出电压相对于输入电压的表达式在以下写出:
关系式(1)可以用于绘制示出作为循环比α的函数的U输出/U输入比值变化的曲线。该曲线在图6的示图中示出为参考标号31。根据已知技术的对于可逆升压型DC/DC转换器的相应的变化曲线也在本示图中示出为参考标号32(参见图3A)。
例如,根据本发明的转换器的值可以如下:
r1=r2=10mΩ
L1=625μH以及L2=1250μH
C1=500μF以及C2=250μF
R=10Ω
斩波频率:20kHz
U输入=25V以及U输出=100V
I输入=40A以及I输出=10A
考虑到开关(MOSFET、IGBT等)的开关频率限制以及为避免在DC/DC转换器中由开关增加的损耗,循环比通常在0.25和0.75之间。在这些条件下,使用根据本发明的转换器的拓扑的增益远高于使用标准拓扑的增益。应注意,在图6中的两条曲线是在相同效率条件下绘制的。
我们现将描述根据本发明的双升压型DC/DC转换器的工作原理。该描述将基于图5中的示图中示出的两个控制信号。我们将在电流从U输入流通至U输出时的工作方向称为顺向以及将在电流从U输出流通至U输入时的工作方向称为逆向。
顺向方向上的工作(升压)
图7A示出了根据本发明的转换器在t=0和t=αT(换言之,Cmd1=0和Cmd2=1)之间的工作阶段期间如何工作。开关Q1和Q3断开而开关Q2闭合。二极管D1自然导通而二极管D2截止。这意味着感应线圈L1和L2可以并联地充电。线圈L1通过输入源U输入来充电而线圈L2通过电容器C1来充电。
图7B示出了根据本发明的转换器在t=αT和t=T(换言之,Cmd1=1和Cmd2=0)之间的工作阶段期间的工作。开关Q1和Q3闭合而开关Q2断开。两个二极管D1和D2保持截止。这导致两个感应线圈L1和L2串联地在输出U输出中放电同时再一次对电容器C1充电。
逆向方向上的工作(升压)
图8A示出了根据本发明的转换器在t=0和t=αT(换言之,Cmd1=0和Cmd2=1)之间的工作阶段期间如何工作。开关Q1和Q3闭合而开关Q2断开。二极管D1和D2自然截止。在该工作阶段,感应线圈L2通过源U输出来充电而感应线圈L1通过电容器C1和输入源U输入来充电。
图8B示出了根据本发明的转换器在t=αT和t=T(换言之,Cmd1=0和Cmd2=1)之间的工作阶段期间的工作。开关Q1和Q3断开而开关Q2闭合。二极管D2自然导通而二极管D1截止。这导致感应线圈L2通过开关Q2在电容器C1中放电以及感应线圈L1通过L1通过续流二极管D2在U输入中放电。
