具体实施方式
下面,参照附图对本发明的适宜的实施方式进行详细说明。此外,在本说明书及附图中,对于实质上具有相同功能的构成要素,赋予相同的附图标记,而省略重复说明。
(实施方式)
图1是表示本发明的实施方式的车辆的结构的图。车辆300例如是小客车、卡车、公共汽车、摩托车等。车辆300包括:开关电源装置100、车载电池110、车载电器150、DCDC(Direct Current to Direct Current,直流-直流)转换器130、以及逆变器120。
开关电源装置100是将从交流电源200供给的交流电转换为直流,并向车载电池110、逆变器120等供给的电力转换装置。后面将描述开关电源装置100的结构的细节。此外,除了车辆300以外,开关电源装置100也可以设置在例如飞机、游戏设备、无中断电力转换电路等中。
交流电源200例如是搭载在快速充电设备上的电源、商业电源等。交流电源200是单相交流电源、两相交流电源、三相交流电源等。车载电池110是储存用于驱动搭载在车辆300上的行驶用电机140(主电动机)、车载电器150等的电力的装置,例如是锂离子电池、镍氢电池等。车载电器150例如是导航、音频装置、空调、电动窗、除雾器、ECU(ElectronicControl Unit,电子控制单元)、GPS(Global Positioning System,全球定位***)模块、车载摄像头等。逆变器120是将直流电压转换为交流电压并向主电动机进行供给的电力转换装置。
接着,参照图2说明开关电源装置100的结构例。图2是表示本发明的实施方式的开关电源装置的结构例的图。开关电源装置100具备开关装置10和多个电力转换电路4-1、4-2、4-3。以下,在不区分多个电力转换电路4-1、4-2、4-3的情况下,将其统称为“电力转换电路4”。
开关装置10具备切换电路2和多个噪声滤波器5-1、5-2、5-3。以下,在不区分多个噪声滤波器5-1、5-2、5-3的情况下,将其统称为“噪声滤波器5”。
在与多个电力转换电路4-1、4-2、4-3分别对应的各个相,设置有噪声滤波器5。噪声滤波器5是用于抑制噪声从交流电源200进入电力转换电路4以及噪声从电力转换电路4流出到交流电源200的噪声除去单元。噪声滤波器5可以抑制差模(differential-mode)和共模(common-mode)的噪声。作为这些噪声的抑制方法,使用在电源供给线(电源线L1、L2、L3)上设置共模扼流线圈、X电容器(跨线电容器(across-the-line capacitor))等,或在电源供给线与接地之间设置Y电容器(旁路电容器(line-by-pass capacitor))等的方法。
在电源线L1上设置的噪声滤波器5-1具备电容器1-1和线圈3-1。电源线L1是在交流电源200为单相交流电源时流动单相电流,在交流电源200为三相交流电源时流动例如U相(第一相)电流的电线。
在电源线L2上设置的噪声滤波器5-2具备电容器1-2和线圈3-2。电源线L2是在交流电源200为单相交流电源时流动单相电流,在交流电源200为三相交流电源时流动例如V相(第二相)电流的电线。
在电源线L3上设置的噪声滤波器5-3具备电容器1-3和线圈3-3。电源线L3是在交流电源200为三相交流电源时,流动例如W相(第三相)电流的电线。
以下,在不区分电容器1-1、1-2、1-3的情况下,将其统称为“电容器1”;在不区分线圈3-1、3-2、3-3的情况下,将其统称为“线圈3”。电容器1是X电容器、Y电容器等。电容器1设置在切换电路2的交流电源200侧。线圈3是共模扼流线圈(common mode choke coil)、常模扼流线圈(normal mode choke coil)等。线圈3例如设置在切换电路2的电力转换电路4侧。此外,线圈3的设置位置不限于图示的例子,也可以设置在切换电路2的交流电源200侧。
但是,在将线圈3设置在切换电路2的交流电源200侧的情况下,当切换电路2的切换继电器2a处于连接交流电源200的电源线L1与电力转换电路4-2的模式时,流经该线圈3-1的电流的额定电流需为在将线圈3设置在切换电路2的电力转换电路4侧时流过线圈3-1的电流的两倍。因此,在将线圈3设置在切换电路2的交流电源200侧时,线圈3的额定值变大,因线圈3的铁损及铜损而产生的热会随之增加。另外,线圈3的铁损导致电力损失增加。因此,优选地,将线圈3设置在切换电路2的电力转换电路4侧。
切换电路2是将向多个电力转换电路4供给交流电流的交流电源200的相,在与多个电力转换电路4分别对应的相和多个电力转换电路4共用的相之间进行切换的切换单元。切换电路2例如具备:切换继电器2a、以及驱动切换继电器2a的未图示的螺线管。该螺线管例如具备:生成与从未图示的驱动电路输出的控制信号对应的电磁力的线圈、以及利用该线圈的电磁力驱动切换继电器2a的柱塞。控制信号是指示切换继电器2a的连接状态的信号,是例如可取高电平或低电平、即可取二值的矩形波信号。通过根据控制信号由柱塞进行驱动,切换继电器2a的连接状态被切换。切换继电器2a根据控制信号,在连接到电源线L1的状态和连接到电源线L2的状态之间进行切换。此外,切换电路2不限于螺线管方式的切换单元,也可以由半导体开关元件构成。
电力转换电路4例如具备:将交流电压转换为直流电压的ACDC(AlternatingCurrent to Direct Current,交流-直流)转换器、和将该直流电压转换为规定值的电压的DCDC转换器。此外,电力转换电路4不限于具备ACDC转换器和DCDC转换器这二者的电路,也可以仅具备ACDC转换器。
接着,参照图3和图4说明开关电源装置100的动作。图3和图4是用于说明开关电源装置的动作的图。在交流电源200是单相交流电源时,如图3所示,通过使切换继电器2a与电源线L1连接,在电源线L1中流动的单相交流电流(电流I1)在切换电路2处被分配到线圈3-1和线圈3-2,并被提供给电力转换电路4-1和电力转换电路4-2。由此,即使在交流电源200为单相交流电源时,也因能够利用多个额定容量小的电力转换电路4而能够增大开关电源装置100整体的额定容量。
另外,在交流电源200是三相交流电源时,如图4所示,通过使切换继电器2a与电源线L2连接,流过电源线L1的第一相交流电流(电流I1)、流过电源线L2的第二相交流电流(电流I2)以及流过电源线L3的第三相交流电流(电流I3)被分别提供给电力转换电路4-1、电力转换电路4-2和电力转换电路4-3。由此,能够利用三个电力转换电路4进一步增大开关电源装置100整体的额定容量。
接着,参照图5至图7,说明开关电源装置100的比较例。图5是表示本发明的实施方式的开关电源装置的比较例的图。此外,在图5中,对与图2相同的构成要素赋予相同的附图标记,并省略其说明。
图5所示的开关电源装置100A具备开关装置10A,来代替开关装置10。开关装置10A具备设置在切换电路2与电力转换电路4之间的多个电容器1-1A、1-2A、1-3A,来代替多个电容器1-1、1-2、1-3。
图6和图7是用于说明图5所示的开关电源装置的动作的图。将切换继电器2a的初始状态设为切换继电器2a连接到电源线L2的状态。当从交流电源200供给单相电力时,切换继电器2a从连接到电源线L2的状态切换到连接到电源线L1的状态。这样,在仅向电源线L1供给交流电的状态下,如图7所示,如果切换继电器2a被切换成与电源线L1连接,则电容器1-1A中储存的电荷被释放会导致产生虚线所示的过电流I。过电流I例如经由切换电路2和电容器1-2A流向接地。过电流I流动的原因是,在电源线L1中,在切换电路2的电力转换电路4-1侧设置有线圈3-1、电力转换电路4-1等,因此由切换电路2和电容器1-2A形成的路径的电阻值比电容器1-1A的线圈3-1侧的电阻值低。
这样,若过电流I流过切换电路2的切换继电器2a,则有可能使切换继电器2a的接点过热,导致接点熔断或接点损耗。另外,如果过电流I流过电容器1-2A,则电容器1-2A的温度会上升,从而因电容器1-2A的静电容降低或电容器1-2A的内部电阻增加,而导致电容器1-2A的寿命缩短。
与此相对地,在本实施方式的开关电源装置100中,电容器1设置在切换电路2的交流电源200侧。因此,电容器1-1的切换电路2侧的电阻值比电容器1-1的交流电源200侧的电阻值高。因此,在向电力转换电路4供给交流电流的状态下,即使切换继电器2a切换到导通状态,上述过电流I也不易在切换电路2等中流动。其结果,能够防止由过电流I引起的切换继电器2a的损耗、电容器1的劣化等。
此外,也可以是,开关电源装置100以如下方式构成。参照图8,说明开关电源装置100的变形例。此外,在图8中,对与图2相同的构成要素赋予相同的附图标记,并省略其说明。
图8是表示本发明的实施方式的开关电源装置的变形例的图。图8所示的开关电源装置100还在电源线L2与电源线L3之间具备切换电路2。利用该结构,能够将从单相电源供给的交流电流分别供给到三个电力转换电路4,因此,能够在利用额定容量较小的三个电力转换电路4的同时,增加开关电源装置100的额定容量。
此外,在本实施方式中,说明了针对一个电源线分别设置一个电容器1和一个线圈3的结构例,但是也可以针对一个电源线设置多个电容器1和多个线圈3。例如,可以在切换电路2的交流电源200侧设置一组或多组电容器1和线圈3,并且在切换电路2的电力转换电路4侧设置一组或多组线圈3和电容器1。由此,能够进一步抑制噪声的进入和噪声的流出。此外,为了防止上述的过电流I的产生,对于设置在切换电路2的电力转换电路4侧的线圈3和电容器1的组中的线圈3,以与切换电路2相邻的方式设置该线圈3。
另外,在对一个电源线设置多组电容器1和线圈3时,优选地,将多个线圈3全部设置在切换电路2的电力转换电路4侧。通过这样构成,与在切换电路2的交流电源200侧设置线圈3时相比,能够抑制线圈3的电力损失。通过在开关电源装置100中设置以上述方式构成的开关装置10,能够实现在提高电力转换效率的同时对噪声具有鲁棒性的开关电源装置100。
虽然上面参照附图描述了各种实施方式,但是不言而喻,本发明不限于这样的示例。显然,只要是本领域技术人员,就可以在权利要求书记载的范畴内想出各种变更例或修改例,可以明确它们当然也属于本发明的技术范围。另外,在不脱离发明的要点的范围内,上述实施方式中的各构成要素可以被任意组合。
以上,对本发明的具体例进行了详细说明,但是这些不过是例示,并非对权利要求进行限定。权利要求中公开的技术包括对以上例示的具体例进行的各种变形、变更。
工业实用性
本发明的一个实施例适合用于停车辅助装置、停车辅助***。
