Abstract

本发明涉及电子中间DC电路，其用在诸如磁阻电动机之类的无刷电动机(1)中，并包括由二极管(4)构成的整流桥(5)以及连接在该整流桥(5)的下游的电容器。为了以结构简单的方式改善该类型电路的设计，具有不同电容的两个电容器(6，7)连接在整流桥(5)的下游。

Description

电子中间直流电路
技术领域
本发明涉及与诸如磁阻电动机之类的无刷电动机一起使用的电子直流中间电路，其包括由二极管构成的整流桥和连接在该整流桥的下游的电容器。
背景技术
在诸如磁阻电动机的无刷电动机(它们进一步用在诸如家用真空吸尘器之类的家用电器中)的情况下，供电受直流中间电路的影响。无源直流桥被用作电源(mains)正弦波电压的初始级，其将电解电容器组充电到输入电压的峰值。该中间电路可以作为储能器(store)，电动机通过整流器从该储能器吸取能量，电动机也能够将其续流(freewheel)能返回给该储能器。由中间电路的反向充电引起的供能网络中的谐波被阻尼衰减，至于各种应用的特点由另外的PFC装置(feature)(例如，功率因子校正扼流圈)来应对(present)。如果该中间电路被充电到电源电压的峰值，则不从该电源吸取出电流。通过从该中间电路的电容器为电动机供电，该电容器被放电，作为放电结果，该中间电路电压下降到电源电压的峰值以下。如果提供的电源正弦波电压的瞬时值此刻又上升到该电压电平之上，则电容器开始重新充电，其导致在供能网络中产生的非正弦电流的突跳(jump)。EN 61000-3标准规定了由此导致的电源谐波的幅度的最大容许值。为了满足此标准，已知的是使用上述PFC装置。
发明内容
根据上述现有技术，可见本发明的技术问题是以结构简单的方式来配置讨论中的这种电子直流中间电路。
该问题首要地通过权利要求1的主题解决，其提供了连接在整流桥的下游的两个电容器，该电容器具有不同的电容。因而根据本发明的技术方案是基于被分成两个单独的电容器的该中间电路的电容器的。它们以这样的方式连接：从电源侧来看，优选地具有低电容的电容器，即薄膜电容器是起作用的(active)，从谐波的标准的观点来看，其不是关键的。续流能被引导到第二个适当较大的电解电容器中。这两个电容器连接成并联电路，该并联电路在电源侧的整流桥和电动机的驱动侧之间。因而例如连接在逆变器或晶体管电路的上游。
下面参照权利要求1的主题描述其它权利要求的特征，但是它们的独立简洁描述也同样有效。
因而提供了一个电容器(优选地为电解电容器)，其具有相对高的若干微法的电容，例如大于50μF或大于250μF，大于500μF或大于1000μF。该电容与电动机的可能的续流能匹配。另一个电容器(优选地为薄膜电容器)具有几微法的较低的电容，例如小于500μF或小于250μF或小于50μF。还优选的是阻流二极管，其与该电容器并联。在一个优选实施例中，其与齐纳二极管并联连接。在该电路工作在所谓的弱供能网络期间，该阻流二极管和齐纳二极管的布置通过将能量传送到续流电容器(较高电容的电解电容器)中，能够降低输入电容器(低电容的薄膜电容器)中产生的过量电压。根据本发明的配置，构成了一种电子直流中间电路，其能够接受来自电动机的续流能，不用此电路的话，将导致在供能网络中产生超出标准的谐波，该技术方案与已知现有技术相比，也减轻了所需重量和减小了所需空间。
附图说明
下面将参照附图来详细描述本发明，这里仅示出了一个实施例。图1示出了示范性电路配置。
具体实施方式
该电路配置用于从能源供应网络2为电动机1(这里是多相的)供电，其中插入有直流中间电路3。
由二极管4构成的整流桥5用作电源正弦电压的初始级。并联连接的两个电容器6和7由该两路桥式整流桥来提供。电容器6是薄膜电容器，具有几微法的低电容。提供电解电容器作为第二电容器7。与电容器6相比，电容器7具有明显较高的电容。其为若干微法，如500μF。
这两个电容器6和7通过一个阻流二极管8彼此连接，它们以如下方式连接：从电源侧来看，仅有形成输入电容器的薄膜电容器6是起作用的，电容器6具有小电容，从谐波标准的观点来看，该电容不是关键的。续流能被引导到第二个适当较大的电解电容器7中。
此外，电容器6和7通过一个由彼此串联连接的电阻器9和齐纳二极管10形成的元件组连接。当该电路工作在所谓的弱供能网络中时，由电阻器9和齐纳二极管10形成的元件组(其与阻流二极管8并联连接)通过将能量传送到续流电容器(电解电容器7)中，起到降低输入电容器中产生的过量电压的作用。
通过晶体管电路(包括晶体管T1和T2)控制电动机3，该晶体管电路连接在电容器组的下游，并且另一个阻流二极管11插入于其间。
公开的所有特征(它们自身)均与本发明相关。因此，相关/所附优先权文件(优先权申请的副本)的公开内容也全部包括在本申请的公开内容中，也为了将这些文件的特征引入于本申请的权利要求中。
