Abstract

本发明涉及一种用于应用在电动车辆中的变压器子电路。该变压器子电路具有带有至少四个MOSFET和与MOSFET并联的电容器的桥电路，还具有与桥电路连接的用作变压器的初级侧的电感。用于逆变器的控制装置设计用于这样影响MOSFET的通断，使得在高于谐振频率的频率下实现运行。

Description

变压器子电路
技术领域
本发明涉及一种用于给电动车辆充电的变压器子电路。
背景技术
为了实现对电动车辆、例如轿车的扩展，需要提供具有给车辆自身的蓄电池再充电的可能性的基础设施。除了通过电缆和插头系统来充电外，也存在通过电感式耦合进行无线的再充电的可能性。对此，使用特殊的变压器，其初级侧和次级侧在空间上通过在从1直至30cm的范围内的气隙隔开。
变压器的布置在车辆下部、例如底部中的一侧被视为初级侧。次级侧是车辆的一部分，并且布置在车辆底部的范围内。取决于车辆的离地间隙和停车位置，也就是说根据初级侧和次级侧的相对的布置，得出变压器漏电感和主电感的不同的值。与其部件是不可分的传统变压器相比，会产生非常高的漏电感值和相对较小的主电感值。
用于初级侧的逆变器典型地构造具有IGBT，并且恰好在谐振频率中运行。由此在电流过零中实现关闭单个的半导体开关，从而导致尽可能低的开关损耗。如果开关时间点并不是恰好位于谐振点，那么损耗显著增加。
发明内容
本发明的目的在于，提供一种用于给电动车辆充电的变压器子电路，其特征在于简化了的结构和在开关损耗方面的改进了的性能。
该目的通过带有权利要求1的特征的变压器子电路来实现。从属权利要求涉及该变压器子电路的有利的设计。
根据本发明的变压器子电路在给电动车辆的蓄电池充电时适用。对此变压器子电路例如安装在确定用于充电的停车位置的底板区域中，并且作为变压器的初级侧，当带有相应的次级侧的电动车辆停留在停车位置上时会得出该变压器。变压器子电路具有带有至少两个半导体开关、特别是四个半导体开关的桥电路。电感与该桥电路连接用于用作所得出的变压器的初级侧。最后，变压器子电路包括用于桥电路的半导体开关的控制装置。控制装置设计用于使得桥电路作为逆变器运行。因此根据本发明，当通过半导体开关的通过电流达到或者经过可确定的阈值时，则实现对半导体开关的断开。根据本发明的MOSFET用作半导体开关。开关频率优选地大于100kHz。换句话说，控制装置设计用于使得半导体开关的通断这样起作用，即在频率与谐振频率相比提高时实现运行。
根据本发明的结构允许开关损耗非常低的运行，因为要切断的电流整流到在MOSFET中始终存在的并联的杂散电容中。同时可能有利的是，实现对运行频率的调整，使得电性能的这种改变得到补偿，通过电动车辆的不同的停车位置在变压器子电路上产生这种改变。由此有利地实现，在车辆的非最优停止位置时也可以进行尽可能低损耗的充电。
半导体开关主动地断开非零的电流以便实现超谐振运行。所断开的电流优选的是在2A到10A之间。准确的开关点在优选的设计中根据电流测量而确定。
符合目的地，在断开半导体开关中的一个之后，半导体开关中的另外一个在例如100ns到200ns的静止时间过去之后接通。在该时间内杂散电容再充电。通过另一个半导体开关的通过电流在此仅仅在下一个电流过零后才首先经过并联的寄生本体二极管。因此有利的是，不需要为了接通而准确地检测过零。
根据设计，半导体开关涉及单个的MOSFET。在可替代的设计中，在逆变器内的四个半导体开关的位置上分别使用几多个单个MOSFET的并联电路。
附图说明
现在借助附图进一步解释优选的然而决不是限制的本发明的实施例。在此示意性地示出特征。其示出：
图1固定的充电电路以及车辆侧的充电电路，
图2固定的充电电路的频率特性，以及
图3漏极电流和漏极源极电压的曲线。
具体实施方式
图1示出了固定的充电电路10以及车辆侧的充电电路20。车辆侧的充电电路20具有车辆侧的线圈21，该线圈作为变压器的一部分。车辆侧的线圈21在本实施例中与二极管整流器22连接，该二极管整流器的输出端与车辆的没有示出的另一个功率电子元件连接。
固定的充电电路10具有固定的线圈16，该线圈电感地与车辆侧的线圈21耦合。在实际环境中，固定的充电电路例如放置在停车场区域内的地面上，其中停车场计划用于给电动车辆无线充电。车辆侧的线圈21又和桥式整流器一起是电动车辆的一部分。电动车辆为了充电而定位在停车场上。所得出的车辆侧的线圈21和车辆侧的线圈16的相对布置是可变的，并且通过车辆位置得出。可变的定位又引起所得出的变压器的电性能的显著可变性，该变压器由车辆侧的线圈21和固定的线圈16构成。
固定的充电电路10除了固定的线圈16之外还具有与此相连接的逆变器，其由第一至第四MOSFET11...14组成。MOSFET11...14中的每一个具有一定的杂散电容，该杂散电容通过并联电路中的各一个电容器15示出。MOSFET11...14在此分为两对，其中一对的MOSFET11...14串联，并且两对彼此并联。固定的线圈16在此利用输出端与这些对中的一对的中点连接，并且利用另一个输出端与另一对的中点连接。在两个对的分别连接了的外侧施加有DC输入电压。
在图1中未示出的可替代的设计中，只使用两个MOSFET11...14。在此两个半桥中的一个、例如右半桥的两个MOSFET13，14由电容器代替，该电容器构成辅助中间电路。
固定的充电电路10的整个结构具有频率特性30，该频率特性在图2中绘出。图2中的频率尺度在此从100kHz延伸至1MHz。频率特性30在该实施例中的频率在156kHz时具有一个显著的最大值。该最大值称为谐振频率。
在图1中未示出的用于固定的充电电路10的控制装置在充电操作中现在这样控制MOSFET11...14，从而实现略微超谐振的运行。MOSFET11...14主动地断开非零的电流。在本实施例中这样控制固定的充电电路10，使得产生160kHz的、也就是说比谐振频率多4kHz的工作频率32。
在图3中示出了具体的通断过程。在图3中示出了MOSFET的漏极源极电压40的曲线以及漏极电流41的曲线。图3中的x轴的图形在此示出了相应于工作频率32的全周期持续时间。可以看出，在漏极电流41明显不为零时在稍低于50％的周期持续时间时实现断开相应的MOSFET11...14。对此，MOSFET11...14中的每一个关断大约5A的漏极电流41。自然这样实现接通相应的MOSFET11...14，即产生逆变器的功能并且在大约100到200ns的静止时间过去之后实现无电压。要关断的电流被整流到MOSFET11...14的始终存在的电容和本体二极管中，并且在超过0A之后，例如在图3中在大约5%的周期持续时间时，主动地流过接通了的MOSFET11...14。
当谐振频率由于固定的线圈16相对于车辆侧的线圈21的定位改变而改变时，因此也保持了略微超谐振的运行。换句话说，实现了工作频率32对相应的相对定位的带宽调整。因此有利的是，不必再准确地检测漏极电流41的过零，因为接通和关闭在任何情况下不再在过零时发生。相应的剩余电流给电容器15再充电，并且因此有助于避免开关损耗。
在固定的充电电路10中例如使用MOSFET11...14来代替IGBT，由此除了至少100kHz的高关闭频率的可能性之外，也不需要用于载流子复合的长静止时间。固定的充电电路10允许补偿较大的气隙差异和车辆侧的线圈21相对于固定的线圈16的横向移动。
